In the procurement decision-making of environmental test equipment, price is always the core sensitive point for purchasers. However, the true value of an environmental test chamber lies not only in the "one-time quotation" during procurement, but also in the total life cycle measurement. Hidden costs such as equipment energy consumption, failure downtime losses, maintenance costs, and service life are the key factors determining whether a high and low temperature test chamber is truly "worth buying". As a benchmark enterprise in domestic environmental test chambers, Lab Companion has redefined the "cost-effectiveness" of environmental test equipment with more than 20 years of in-depth experience — it is not a compromise on low prices, but the implementation of the core value of "optimal total cost throughout the life cycle".
I. Lab Companion: More Than 20 Years of In-Depth Cultivation, Laying a Solid Foundation for "Cost-Effectiveness" from the Source
An enterprise's ability to achieve "good quality at a reasonable price" is never a short-term game of cutting material costs, but stems from the systematic optimization of the entire chain from R&D, manufacturing to quality control. Founded in 2005, Lab Companion is headquartered in Dongguan City, Guangdong Province, with a standardized production base of over 6,000 square meters. It has three R&D and manufacturing centers in Dongguan, Kunshan and Chongqing, and 16 service centers nationwide, with an annual output exceeding 2,000 environmental test equipment. As a national high-tech enterprise and a specialized, refined, characteristic and innovative enterprise, the company has invested hundreds of millions of yuan in tackling core technologies, overcoming industry pain points such as temperature control accuracy, temperature switching efficiency and energy conservation, and has won 43 patents and 3 software copyrights, building an insurmountable technical barrier.
1. Independent R&D of Core Control System, Breaking Technical Dependence to Reduce Costs and Increase Efficiency
Lab Companion's independently developed C100 type PID temperature and humidity control + fuzzy logic control system has the ability to automatically combine the working conditions of refrigeration, heating, vacuum and other subsystems. Its original cold-end regulation control method has obtained national patent certification, which fundamentally solves the industry problem of high energy consumption of traditional control systems. By independently developing the core controller, Lab Companion not only completely gets rid of the procurement dependence on external equipment, but also continuously reduces production and operation and maintenance costs in the process of technological iteration, providing core support for "high quality at low price".
2. Standardized and Large-Scale Manufacturing, Spreading Unit Costs While Ensuring Quality
Lab Companion adopts a process-based assembly line operation mode, with complete process documents and process specifications for each process. It has introduced high-precision processing equipment such as Hong Kong LFK CNC bending machine and Germany TRUMPF laser cutting machine, which not only ensures the processing accuracy of products, but also greatly improves production efficiency. Large-scale production effectively spreads the fixed cost of unit products, while high-standard assembly technology reversely reduces the frequency of after-sales maintenance — this positive cycle of "manufacturing efficiency → cost optimization → quality stability" is the underlying logic for Lab Companion to achieve "domestic brand price and international brand quality".
3. Strict Factory Inspection, Reducing Hidden After-Sales Costs from the Source
Lab Companion implements a full-process strict inspection for each factory equipment, comprehensively debugs the performance of each system, and completes the trouble-free continuous operation test before leaving the factory to ensure that the equipment can be put into use with zero failure when it arrives at the user's site. This pre-quality control verification greatly reduces the failure rate and after-sales costs after the equipment arrives at the site, and also enables Lab Companion to dare to promise "whole machine warranty ≥ 2 years and core components warranty 5 years", avoiding worries about later maintenance for purchasers.
II. Four Core Dimensions, Decoding the Core Advantages of Lab Companion's "Cost-Effectiveness"
The core of Lab Companion's "cost-effectiveness" is "the lowest total cost throughout the life cycle", which can be intuitively reflected from four dimensions: procurement, operation, maintenance and use. Each advantage accurately hits the core pain points of purchasers.
1. Procurement Cost: The Price of the Same Configuration is Only 50%-70% of Imported Brands, Refusing Quality Compromise
The most direct embodiment of high cost-effectiveness is the procurement price advantage: the price of Lab Companion's environmental test chambers with the same configuration is 30%-50% lower than that of international brands, and the mid-range models only cost 50,000 to 150,000 yuan, which greatly reduces the procurement budget pressure. However, this advantage is not at the cost of sacrificing quality; on the contrary, it does not compromise on the configuration of core components: electrical accessories are selected from international first-line brands such as Siemens, Schneider and ABB; the refrigeration system is equipped with Germany Bitzer, Germany GEA Blogg and US Copeland compressors; refrigeration accessories are all from well-known international manufacturers such as Denmark Danfoss and US SPORLAN. "Using good materials and controlling costs well" allows purchasers to enjoy core configurations of international quality at domestic prices.
2. Operation Cost: Energy Consumption is 28%-38% Lower Than the Industry Average, Saving Considerable Electricity Costs in the Long Term
Environmental test chambers mostly operate continuously for 24 hours, and electricity costs are long-term and huge hidden expenses. Lab Companion has invested special R&D in energy conservation and consumption reduction, and achieved energy-saving breakthroughs through a number of technological innovations: the unique design of cold and hot bypass regulation and liquid hammer prevention system keeps the compressor in the best working condition, taking into account service life and refrigeration efficiency; the refrigeration system adopts the inverse Carnot cycle design, which greatly improves the refrigeration efficiency; the cold-end regulation function of the C100 control system further reduces invalid energy consumption. For production lines or R&D laboratories that operate for a long time, tens of thousands of yuan in electricity costs can be saved every year, significantly reducing the total cost of ownership throughout the life cycle.
3. Maintenance Cost: Three-Year Failure Rate is Less Than 3%, Greatly Reducing Downtime Losses
Equipment failure brings not only maintenance costs, but also hidden losses such as test interruption, R&D delay and production schedule disruption. The three-year failure rate of Lab Companion's equipment is less than 3%, which is far better than the industry average. The reliability comes from three guarantees: first, international first-line core components lay a foundation for long-term stable operation; second, the independently developed Q8 series control system has complete self-inspection, fault early warning and alarm functions, realizing "early discovery and early investigation"; third, the efficient service network built by 16 national service centers achieves "2-hour response in the Pearl River Delta and 48-hour on-site service nationwide", which is far beyond the response cycle of more than 72 hours of imported brands, minimizing downtime and reducing losses.
4. Usage Cost: Flexible Customization, Avoiding Space Waste and Secondary Investment
The mismatch between the volume, temperature range and other parameters of the environmental test chamber and the actual test needs will cause space waste, increased energy consumption, or forced secondary procurement due to insufficient parameters. Lab Companion provides full-scenario customization solutions: the high and low temperature humidity test chamber covers a variety of standard volumes such as 34L, 64L, 100L to 1000L, and also supports non-standard customization such as 36L-1000L volume, -80℃ to 250℃ special temperature range and anti-corrosion inner tank, allowing purchasers to accurately match their own needs without spending "wasted money". In addition, the delivery cycle of conventional models is only 7-30 days, 60% faster than that of international brands, and non-standard customization can also complete the whole process from design, production to delivery quickly, improving procurement efficiency.
III. Typical Product Series: Adapting to Different Budgets, Each is a Cost-Effective Choice
Aiming at different scenarios and budgets, Lab Companion has created a diversified product series, which takes into account practicality and cost-effectiveness, and meets various procurement needs:
1. First Choice for Small and Medium-Sized R&D Laboratories: High and Low Temperature Humidity Test Chamber
Covering a temperature range of -40℃/-70℃ to +150℃ and a humidity range of 20%-98%RH, it is equipped with a C100 type PID controller, which is easy to operate and stable in operation. The price of mid-range models is 50,000 to 150,000 yuan, which is suitable for the R&D and testing needs of university laboratories and small and medium-sized electronic enterprises, and is an entry-level cost-effective choice.
2. Adapted for Mass Quality Inspection on Production Lines: Constant Temperature and Humidity Test Chamber
The temperature range covers -20℃ to +150℃, which is specially designed for rapid sampling inspection of electronic components and consumer electronic products in the production link. It has stable operation and low energy consumption, adapts to 24-hour continuous operation scenarios, and takes into account quality inspection efficiency and long-term use costs.
3. Large-Scale Projects and Extreme Environment Simulation: Walk-In Constant Temperature and Humidity Test Chamber/Large-Scale High and Low Temperature Chamber
Aiming at scenarios such as vehicle testing and large-scale equipment verification, Lab Companion provides walk-in environmental test chambers and large-scale high and low temperature humidity test chambers. Adopting a modular assembly design, it is easy to install, and users can adjust the size and structure of the test chamber according to subsequent test needs, effectively reducing future expansion costs and adapting to the high-end needs of large enterprises and scientific research institutes.
IV. Ultimate Verification of Cost-Effectiveness: Real Recognition from the Market and Customers
The "cost-effectiveness" of a product is ultimately determined by the market and customers. Lab Companion's service network covers 16 cities nationwide, and its cooperative customers include industry leading enterprises such as Huawei, Gree, BYD, State Grid and China Southern Power Grid, as well as top scientific research institutes such as Tsinghua University, National University of Defense Technology, Chinese Academy of Sciences and National Institute of Metrology, with a customer repurchase rate as high as 85%.
From the first batch of equipment delivered in 2005 that is still running stably to becoming a long-term partner of industries with high requirements for equipment reliability such as new energy, semiconductors and military industry, Lab Companion has proved its core competitiveness of "cost-effectiveness" through years of market precipitation — it is not a short-term price advantage, but a long-term value return.
V. Procurement Guide: How to Accurately Evaluate the "Cost-Effectiveness" of Environmental Test Chambers?
For purchasers, to judge the "cost-effectiveness" of an environmental test chamber, it is necessary to jump out of the misunderstanding of "simple price comparison" and comprehensively evaluate it from the following four dimensions to achieve "worth buying and saving in use":
1. Dimension 1: Matching Degree Between Procurement Price and Configuration
Low prices are often accompanied by quality compromises. The premise of fair price comparison is "the same configuration" — compare prices on the basis of consistent key parameters such as temperature control accuracy, volume and core component brands. The price of Lab Companion's products with the same configuration is 30%-50% lower than that of international brands, which is based on this comparable standard, achieving "no compromise on quality and more favorable price".
2. Dimension 2: Accurate Calculation of Annual Energy Consumption Costs
Low-cost equipment ignoring energy consumption will generate high hidden costs in long-term use. Taking a conventional constant temperature and humidity test chamber as an example, the annual operating electricity cost difference of equipment from different brands can reach tens of thousands of yuan. Lab Companion's energy consumption is 28%-38% lower than the industry average, which can save tens of thousands of yuan in electricity costs in long-term use and greatly reduce the total cost of ownership throughout the life cycle.
3. Dimension 3: After-Sales Response and Maintenance Cycle
The downtime loss caused by equipment failure is often far more than the maintenance cost. When purchasing, it is necessary to focus on the after-sales system: Lab Companion's service commitment of 16 national service centers, 48-hour on-site response and whole machine warranty ≥ 2 years can minimize downtime and reduce hidden losses.
4. Dimension 4: Flexibility of Non-Standard Customization and Future Expansion
Environmental test chambers are long-term use equipment, and the iteration of enterprise products will bring new test needs. Lab Companion's full coverage of 36L-1000L volume and -80℃ to 250℃ wide temperature range customization capacity can reserve space for the long-term development of enterprises, avoiding secondary procurement caused by changes in needs.
Conclusion
The true "cost-effectiveness" is never "low price and cheap", but "the lowest total cost and the highest comprehensive benefit throughout the life cycle". With more than 20 years of in-depth technological cultivation as the foundation, independent R&D to break technical barriers, large-scale manufacturing to reduce costs, strict quality control to ensure reliability, and efficient services to avoid hidden losses, Lab Companion has written a clear annotation for "cost-effectiveness" in the 2026 environmental test equipment market — allowing purchasers to spend less money to obtain more stable, energy-saving and cost-effective environmental test equipment, realizing the dual optimization of "procurement cost and long-term value".
In the field of environmental reliability testing, a high-performance high & low temperature rapid thermal cycling chamber serves as core equipment for enterprises to control product quality and verify product reliability. As a leading brand deeply engaged in the environmental testing equipment industry for many years, Lab Companion boasts in-depth insights into testing demands across various industries and extensive experience in product R&D and practical application. We have accurately identified the core characteristics of a reliable and efficient high & low temperature rapid thermal cycling chamber. From Lab Companion’s professional perspective, this article systematically breaks down the five core performance indicators that must be focused on during the selection process, providing professional guidance for industry customers to help them make accurate selections, avoid procurement pitfalls, and make informed decisions that align with their actual needs.
1. Temperature Range & Rate of Temperature Change – Define Testing Boundaries and Determine Testing Efficiency
Temperature range and rate of temperature change are the basic performance benchmarks of high & low temperature rapid thermal cycling chambers. They directly determine the breadth of the equipment’s application scenarios and affect the efficiency and pace of testing processes, making them the primary consideration in equipment selection.
Temperature Range: The key is to ensure the equipment’s temperature range fully covers the extreme high and low temperature environments that products may encounter throughout their service life, avoiding limited testing scenarios due to insufficient range. Lab Companion high & low temperature rapid thermal cycling chambers offer a temperature interval of -70℃ to +150℃ and even wider ranges, with fully linear controllability throughout the process—not just transient peak values. This ensures stable and precise temperature regulation during testing, adapting to the testing needs of electronics, automotive, military, semiconductor and other industries.
Rate of Temperature Change: During selection, priority should be given to distinguishing between no-load rate and loaded rate—the latter is more consistent with actual testing scenarios (simulating the heat capacity of real samples) and thus more valuable for reference. A high temperature change rate (e.g., 15℃/min and above) can significantly shorten testing cycles and improve testing efficiency, provided that temperature uniformity and stability are not compromised; otherwise, test data will be distorted. Equipped with a high-efficiency cascade refrigeration system and independently developed precise temperature control algorithms, Lab Companion achieves stable and nominal rapid linear temperature changes even under loaded conditions, truly realizing "efficient testing without compromise" and effectively enhancing testing efficiency while reducing time costs for customers.
2. Temperature Uniformity & Fluctuation – Lay the Foundation for Reliable Test Data
Temperature uniformity and fluctuation are core indicators for evaluating the consistency and stability of the internal testing environment. They directly affect the repeatability and authority of test results, and are critical prerequisites for ensuring valid test data.
Temperature Uniformity: Refers to the consistency of temperatures at various testing points within the equipment’s working space (industry standard: ≤±2.0℃). Poor uniformity will result in samples of the same batch being exposed to different thermal stress environments, rendering test conclusions meaningless and even misleading product R&D and quality judgments.
Temperature Fluctuation: Refers to the variation amplitude of the control point temperature over time (industry standard: ≤±0.5℃). Excessive fluctuation introduces additional thermal stress interference to samples, compromising the accuracy and rigor of testing.
Lab Companion Practice: Leveraging Computational Fluid Dynamics (CFD) technology, Lab Companion optimizes air duct structure design and employs scientifically arranged high-precision sensors to maintain exceptional temperature uniformity and minimal fluctuation even under full-load testing conditions. All equipment performance data is verified in strict accordance with national standards such as GB/T 10592, eliminating "nominal-only parameters" and ensuring every set of test data is authentic, reliable and traceable.
3. Load Capacity & Thermal Load Impact – Verify the Equipment’s Practical Performance
Most equipment specifications on the market are tested under ideal no-load conditions. In actual testing, however, the volume, weight and heat generation (thermal load) of samples directly affect the equipment’s real operational performance—this is also the core criterion for judging whether equipment performs as advertised.
Real Load Evaluation: During selection, clarify the maximum sample size, weight and heat dissipation power (W) that the equipment can support. Especially for electronic products requiring powered testing, the heat generated during operation must be fully offset by the equipment’s cooling capacity to ensure stable low-temperature testing and prevent test failure due to unbalanced thermal load.
Loaded Performance Verification: To ensure customers purchase equipment matching their actual testing needs, Lab Companion proactively recommends and supports customers in conducting simulated load tests—installing heating devices equivalent to sample thermal loads inside the chamber to on-site verify whether the equipment’s temperature change rate, temperature uniformity and extreme low-temperature performance still meet standards under real working conditions. This completely eliminates the problem of "qualified under no load but invalid under load" and guarantees robust practical performance.
4. Control System & Data Integrity – The Intelligent "Brain" of Operation and Guardian of Compliant Testing
With the advancement of laboratory intelligence and standardization, advanced control systems and rigorous data management systems have become essential requirements for modern environmental testing laboratories. For regulated industries in particular, data compliance is of paramount importance.
Intelligent Control System: A high-quality control system requires three core capabilities—high-precision temperature control, an intuitive and user-friendly interface, and powerful multi-segment programming functions. It should also be equipped with comprehensive safety protection and fault self-diagnosis features to reduce operational complexity and avoid operational risks. Lab Companion adopts an independently developed intelligent controller that supports complex temperature profile programming and pre-installs multiple internationally recognized testing standard programs. It features convenient operation and precise temperature control, adapting to the customized testing needs of various industries.
Data Integrity & Traceability: For regulated industries such as automotive, medical, military and semiconductor, equipment software must strictly comply with international regulations including FDA 21 CFR Part 11, with functions such as electronic signatures, complete audit trails, hierarchical authority management and tamper-proof data storage to ensure the compliance and traceability of test data. Lab Companion provides targeted software options meeting such stringent requirements, fully safeguarding the compliance of customers’ test data and supporting smooth passage of various industry audits.
5. Long-Term Reliability, Energy Efficiency & Service Network – Evaluate Full Lifecycle Value
High & low temperature rapid thermal cycling chambers are long-term investment equipment. Their long-term operational stability, energy consumption and after-sales support directly determine the equipment’s full lifecycle cost—an easily overlooked yet critical indicator in selection.
Long-Term Operational Reliability: The long-term stability of equipment relies on the quality of key components (e.g., compressors, controllers, sensors) and overall design lifespan. Lab Companion insists on adopting world-renowned brand core components, combined with stringent product aging tests and Factory Acceptance Tests (FAT), to ensure each delivered unit features high reliability and long service life, minimizing downtime and ensuring uninterrupted testing operations.
Operational Energy Efficiency: High energy consumption constitutes a major part of long-term operating costs, especially for laboratories operating 24/7, where energy-saving performance directly impacts operational expenses. Incorporating variable frequency regulation technology and high-efficiency heat exchange systems, Lab Companion’s energy-saving designs significantly reduce energy consumption while maintaining equipment performance, helping customers cut long-term operating costs and achieve the dual goals of "efficient testing and green energy conservation".

Before starting the machine, it is necessary to comprehensively check whether various indicators such as equipment power supply, refrigerant, refrigerating oil, and water level are normal, and confirm that the sample placement complies with the specifications (100~150mm away from the box wall) to avoid affecting the temperature uniformity inside the box. After starting the machine, first start the equipment's preheating or precooling program, and put the sample into the box only after the temperature inside the box reaches the set initial temperature to prevent the sample from being damaged by sudden cold and heat. During the test, it is necessary to observe the equipment operation status and sample changes in real time, and it is strictly prohibited to open the box door at will. If it is necessary to open it, it is necessary to first pause the heating and humidification functions, and then operate after the temperature inside the box tends to room temperature. After the test, first close the test program, take out the sample after the equipment naturally returns to room temperature, then turn off the equipment power supply, clean up the debris inside the box, and complete the equipment operation record for subsequent traceability and maintenance.
IV. Common Operation Mistakes and Avoidance Methods
Combined with the actual application scenarios of the Lab Companion High-Low Temperature Rapid Temperature Change Chamber, most equipment failures and test errors are caused by operation mistakes, which need to be focused on avoiding and standardized correction:

Avoidance method: Detect the heat generation power of the sample in advance, reasonably match the equipment volume and temperature change rate, and ensure that the parameters are compatible with the sample characteristics.
Mistake 2: Opening the box door at will during the test, leading to drastic fluctuations in the temperature inside the box and affecting test accuracy. Avoidance method: Strictly follow the operation procedures, do not open the box door unless necessary, and if it is necessary to open it, first pause the relevant functions and operate after the temperature stabilizes.
Mistake 3: Directly turning off the equipment power supply after the test without completing the temperature recovery and cleaning process, damaging equipment components. Avoidance method: Strictly follow the process of "closing the program → natural temperature recovery → taking out the sample → cleaning the equipment → turning off the power supply" to do a good job in subsequent equipment maintenance.
In addition, Lab Companion can provide professional operation training services to help operators quickly master equipment use skills, fully avoid various operation mistakes, and ensure that the test work is carried out efficiently, safely and orderly.
I. Core Function of Refrigerant Oil: Ensuring Long-term Stable Operation of the Compressor
As the "heart" of the refrigeration system of the high and low temperature rapid temperature change chamber, the compressor's operating status directly determines the overall performance of the equipment. Refrigerant oil is the key medium to maintain the normal operation of the compressor, mainly undertaking four core functions: lubrication, cooling, sealing, and cleaning. Specifically, refrigerant oil can effectively reduce the friction loss of moving parts inside the compressor, lower the operating temperature during operation, seal the refrigerant leakage channel, and clean internal carbon deposits and impurities, thereby fundamentally extending the service life of the compressor. Lab Companion high and low temperature rapid temperature change chambers are equipped with high-quality semi-hermetic piston compressors, matched with specially adapted refrigerant oil. The purity of the oil and the matching degree of its performance parameters with the equipment directly affect the operating efficiency, energy consumption level and overall service life of the refrigeration system. Therefore, strictly following the refrigerant oil replacement specifications and controlling the replacement cycle is a core link in the daily maintenance of the equipment and a key measure to avoid refrigeration system failures.
II. Lab Companion Refrigerant Oil Replacement Specifications: Detailed Cycle Standards and Operation Steps
Combined with industry standards and the structural characteristics of Lab Companion equipment, clear cycle standards and operation specifications have been formulated for the replacement of refrigerant oil in semi-hermetic piston compressors to ensure that the replacement process is scientific and standardized, and the equipment performance is not affected.

The purpose is to remove metal debris and impurities generated during the factory inspection and initial operation of the equipment to avoid wear of internal parts of the compressor;
2. Routine Replacement: After the first replacement, the subsequent replacement cycle should be flexibly adjusted according to the oil quality and actual operating conditions. Under normal operating conditions, it should be replaced every 10,000 to 12,000 hours;
3. Emergency Replacement: If abnormal oil quality (such as discoloration, impurities, peculiar smell, etc.) is found during daily inspection, there is no need to wait for the fixed cycle. The equipment must be shut down immediately for inspection and refrigerant oil replacement to avoid the expansion of faults.
(II) Replacement Operation Steps
Lab Companion provides users with a standardized operation guide with clear and operable steps, as follows:
1. Preprocessing: Start the equipment and run it until the refrigeration system reaches the normal working temperature, and continue to run for 1 hour to ensure that the refrigerant oil circulates fully, facilitating the discharge of internal impurities;
2. First Oil Drainage: Turn off the equipment power supply. After the system pressure drops to the normal range, drain all the old oil in the oil tank, cooler and all filters to ensure no residual old oil;
3. Secondary Flushing: Add new refrigerant oil to the oil tank to the minimum oil volume required for equipment operation (about 1/2 of the oil tank volume), start the machine and run it to the normal working temperature for 1 hour, then shut down and drain the flushing oil in the oil tank again;
4. Tertiary Flushing and Cleaning: Repeat the above secondary flushing steps. After completing the third oil drainage, thoroughly clean the filters and filter screens to remove residual impurities and old oil traces;
5. Adding New Oil: Add Lab Companion specially adapted refrigerant oil to the oil tank until it reaches the normal oil level specified by the equipment, ensuring sufficient oil volume and no leakage;
6. Test Run: Restart the equipment and run it for 15 minutes.

Only after confirming that there is no abnormality can it be put into normal use.
III. Oil Quality Judgment Skills: Timely Avoid Equipment Operation Hidden Dangers
In addition to strictly following the fixed replacement cycle, the oil quality status can be quickly judged by observing the oil quality, color and smell of the refrigerant oil during daily operation and maintenance, so as to avoid compressor damage and refrigeration system failures caused by oil deterioration in advance. The specific judgment standards are as follows:
1. Normal State: The refrigerant oil is transparent and clear, with no visible impurities or peculiar smell, indicating that the oil quality is good and can continue to be used normally;
2. Mild Abnormality (Yellow Oil Color): If the oil color turns light yellow or yellow, carefully observe whether there are impurities or burning smell, and check whether air enters the refrigeration system causing oil oxidation; if no moisture or impurities are detected, it can be temporarily not replaced, but the inspection cycle should be shortened; if the oil color is dark and accompanied by slight impurities, the new oil should be replaced in time, and the system should be simply cleaned;
3. Severe Abnormality (Brown Oil Color): If the oil color turns dark brown or black brown and is accompanied by obvious burning smell, stop the machine immediately and detect the resistance value of the compressor motor winding; if the winding insulation is good, the refrigerant oil must be completely replaced and the refrigeration system must be fully cleaned; if the winding insulation is abnormal, contact after-sales service to check the compressor failure to avoid further damage to the equipment.
