48000 fixed & combined dehumidifier

Description

Using a combination of frozen type moisture eliminator and cellular wheel type moisture eliminator,the fixed and combined dehumidifier is applied to special painting operations in fixed place throughout the year.In summer, it makes frozen type moisture eliminator as center, cellular wheel as assistant.In spring and autumn, it combines frozen type moisture eliminator and cellular wheel type moisture eliminator.In winter,it uses cellular wheel type moisture eliminator.

This type of dehumidifier's compressors of refrigeration system are BITZER screw compressors with four-stage load adjusting function, which will benefit energy saving and improving the operation stability.

According to the inlet air conditions and supply air requirements,the equipment can select automatically different operating modes with the PLC program.The operating modes include refrigeration operation, refrigeration combined with wheel operation, the wheel operation,and refrigeration and wheel combined with heating operation.These operating modes can meet the requirments of all operating condition.
