Air dehumidifiers
MID / MSP series

Air dehumidifiers of MID and MSP series are designed for industrial or pool areas. They are usually installed in the environments like public and private pools, dairy plants, basements, cellars and other applications, where humidity control is essential so that the structure or the goods do not get damaged
