Even with a waterproof structure, the internal temperature can drop by just a few degrees, leading to high humidity and condensation. Are you using it beyond the specified humidity range of the product?
The cause is a large amount of water vapor! The challenge is how to remove humidity and suppress mold and decay.
Protect cultural properties and artworks from drying out! Preserve specimen materials that require a stable humidity environment throughout the year.
Protect electronic equipment in the cubicle from moisture and support stable operation.
Using natural water as a cooling heat source, we have improved room temperature in high-temperature and high-humidity environments that were previously difficult to enhance. Here is an example of improving room temperature from 40°C to 25°–29°C.
In summer, it uses super high-efficiency heat exchangers and water for continuous air conditioning. In winter, it utilizes waste heat from the return hot water of the cooling tower for inexpensive heating. A simple heating and cooling device, PEPO.
