Coolant Selection
Coolant is a crucial factor affecting the stability of liquid cooling tests. A suitable coolant should be selected based on the testing requirements to ensure stable equipment operation and reliable test results.
1. Select the Appropriate Coolant Based on the Test Temperature
Different types of coolants have different applicable temperature ranges. When conducting low-temperature tests, a dedicated antifreeze with a freezing point lower than the minimum test temperature should be selected to prevent coolant freezing, which could lead to blockage of the circulation system or abnormal equipment operation.
2. Select the Appropriate Coolant According to Equipment Requirements
The flow properties of coolant change with temperature, affecting circulation efficiency. It is recommended to select a suitable cooling medium based on equipment requirements and keep the coolant clean to ensure stable heat transfer performance.
3. Regularly Check and Replace the Coolant
During long-term equipment operation, coolant performance may degrade. It is recommended to regularly check the coolant condition according to equipment maintenance requirements and replace it promptly to ensure the long-term stable operation of the liquid cooling system.

Frequently Asked Questions
The following are some frequently asked questions about the high and low temperature liquid-cooled testing machine (-30°C). Please contact us directly if you have any further questions.
1. What Ramp Rates Can I Achieve Between -20°c and +95°c?
The heating and cooling rates depend on several factors. Generally, the system can achieve a faster heating and cooling rate under no-load conditions, but the rate decreases with increasing load in actual testing. If you have specific heating and cooling rate requirements, we can provide a suitable configuration solution based on your testing needs.
2. Does the System Support Multi-segment Program Editing?
Yes. The system can edit 100 programs, each with 40 segments, which can run synchronously with high and low temperature programs.
3. How Long Does the Coolant Last Before Needing Replacement?
The coolant's lifespan is typically 6 months to 2 years, depending on the coolant type, operating temperature range, usage frequency, and routine maintenance.
4. What if the Equipment Temperature Does Not Reach the Set Value?
First, check if the coolant level is sufficient and if there are any leaks in the system. Next, check if the compressor is operating normally and if the cooling system is functioning properly. If the problem persists, it may be due to insufficient refrigerant or a control system malfunction, requiring contact with a professional repair technician.
5. What Is the Difference Between a High and Low Temperature Liquid-Cooled Testing Machine and a Regular Temperature Test Chamber?
The main difference lies in the temperature control method and performance. A high and low temperature liquid-cooled testing machine uses liquid as the heat transfer medium, resulting in faster temperature changes and more precise temperature control, making it suitable for testing scenarios with high temperature response requirements. A regular temperature test chamber typically uses air circulation, resulting in slower temperature changes, but it is less expensive.
