Treatment of Ice in High and Low Temperature Test Chamber

Many friends who use the high-low temperature test chamber know that when they do the low-temperature test at regular time, they may encounter the phenomenon of evaporator icing in the box. This phenomenon is not surprising, but it should be paid attention to. If left untreated for a long time, it will affect the operating instructions of the compressor and eventually cause damage to the compressor.
How to avoid the latter to deal with the problem of ice inside the high and low temperature test chamber?
We can deal with the following aspects:
1. Check whether the box is sealed. If there is air leakage, seal it with silica gel.
2. Install the heating device in the internal evaporator attachment, and set the timing frosting function.
3. Use the high temperature generated by the compressor for regular defrost setting in the refrigeration system.
The above methods proposed by OTS hope to be helpful to you!
