How to Maintain a High and Low Temperature Alternating Test Chamber Properly?

The primary function of a high and low-temperature alternating test chamber is to assess the adaptability of product materials under various climatic conditions. This helps in understanding product characteristics and improving quality. Users can conduct tests under a range of climatic conditions, including low temperature, high temperature and humidity, low temperature and low humidity, dew formation, and temperature cycling. This equipment is indispensable in fields such as defense industry, aerospace, automotive electronics, plastics and chemicals, and pharmaceuticals.
By testing relevant products or materials across industries, users can evaluate the heat resistance, cold resistance, moisture resistance, and dryness resistance of products. To achieve these capabilities, the test chamber has strict requirements for the materials and design of the box, as well as the internal components and systems. This means that such a meticulously crafted device comes at a high price.
Generally, the price of a conventional high and low-temperature alternating test device ranges from tens of thousands to over a hundred thousand. If higher technical requirements or larger box sizes are needed, the price can be even higher. Given this, after carefully selecting the right device, users should use and maintain the equipment properly to maximize its value and ensure it is worth the investment.
So, how can users properly maintain and care for the test equipment?
Firstly, users should keep the test chamber clean, maintaining a tidy workspace. Especially when the equipment is not in use, a thorough cleaning should be conducted to keep the workspace dry. Drain any standing water from the water tank and trough, and dry them with a cloth to prevent moisture residue. Finally, pay attention to dust and moisture prevention for equipment stored long-term.
Additionally, regular dust removal for the electrical control system is essential. Check for any loose, rubbing, or unstable wiring in the equipment’s various components. Before restarting the equipment after long-term storage, conduct a safety inspection to prevent malfunctions.
Secondly, the humidification water supply system of the test equipment must be kept clean. With prolonged use, the capillary holes of the water leveler are likely to be clogged by water impurities. Therefore, maintaining the cleanliness of the water supply system is crucial, and any blockages should be promptly removed by disassembling and clearing the system.
Lastly, monitor the transition and operational status of the refrigeration system. After completing high-temperature tests (≥60°C), do not immediately start low-temperature testing. Instead, open the chamber door to allow the temperature inside to drop to near ambient levels before beginning low-temperature testing. This ensures stable and smooth operation and extends the lifespan of the high and low-temperature alternating test chamber.
