Common Maintenance Tips for High and Low Temperature Test Chambers

Release time:2025-03-25
High and low temperature test chambers are essential testing devices in the fields of aviation, automotive, scientific research, chemistry, building materials, and more. They are used to test and determine the parameters and performance of electrical, electronic, and other products and materials after exposure to high temperature, low temperature, or constant temperature environments. To effectively extend the service life of these test chambers, it is crucial to follow scientific maintenance and care practices. Below are several methods to ensure the long-term and efficient operation of these devices:
High and Low Temperature Test Chambers
Maintenance tips for high and low temperature test chambers are as follows:
  1. The area around the machine, including the bottom surface, should always be kept clean. Before operating the test chamber, internal impurities should be removed, and the test chamber should be cleaned at least once a year.
  2. Under normal circumstances, the condenser should be cleaned every three months. If the compressor is air-cooled, regularly inspect the condenser fan and clean the condenser to remove dust and dirt to ensure good ventilation and heat exchange performance. If the compressor is water-cooled, in addition to ensuring the correct water pressure and temperature, it is also necessary to ensure the appropriate flow rate and regularly clean the inside of the condenser to maintain continuous heat exchange performance.
  3. When the machine is operating below 0℃, opening the door should be avoided as much as possible. Opening the door during low-temperature testing can easily cause the evaporator and other parts inside to freeze, especially at lower temperatures, where the situation can be more severe. If it is necessary to open the door, the opening time should be minimized.
  4. After completing a low-temperature test, it is essential to set the temperature condition to 60℃ and dry the chamber for about half an hour to prevent affecting the measurement time for the next test condition or causing freezing.
  5. After using the high and low temperature test chamber, it is recommended to clean the chamber with clean water to keep the equipment clean. After cleaning, the chamber should be air-dried to maintain dryness.
  6. Maintain a professional and dedicated management approach. Units with the capability should periodically send personnel to the manufacturer for training to acquire more professional maintenance and repair skills.
  7. When the product is not in use for an extended period, it should be powered on once every half month for no less than one hour each time.
To ensure the long-term use of high and low temperature test chambers, regular inspection and maintenance are a must. Always read the instruction manual carefully before operating the machine.
Recommendation
The salt spray test chamber is primarily used to create an artificially simulated salt spray environment for evaluating the corrosion resistance of metals and their alloys, metal coatings, organic coatings, anodic oxide films, and conversion coatings.
In this chapter, we will discuss the correct method for placing test samples in a high/low temperature test chamber.
During the use of a salt spray test chamber, certain problems may arise that require troubleshooting and resolution. If your salt spray test chamber encounters any of the following issues, you can apply these solutions.
The HAST test chamber is a specialized device designed to accelerate the aging process of materials and products by simulating extreme environmental conditions—high temperature and high humidity.
