Different dehumidification capacity will match different cultivation size.  The largest model SDD-960L can meet dehumidification 2020 pints/day (960L/D) at environment 86℉ RH80%. It is widely used for controlling humidity while cultivating cash crops in North America. 

Thickened frame metal body is designed for long life installation on ceiling. Saving each floor space for cultivation. Duct kits can be connected on both inlet and outlet. 

The accurate humidity controller is already fixed with comprehensive logic circuit. Plants  have different humidity requirements with different growth periods. Setting different humidity requirements at different growth periods will maximuize fruitful performance.    Owners do not need additional  cost to buy controllers again. On the other hand, the third-party controller system can be connected to SDD OEM models if requested in advance. 

The optional filters are available for SDD series. Normal filters, medium efficiency filters or high efficiency filters can be chosen for different branding requirements.

Principle of Dehumidifier
best price dehumidifier
The priciple of air circulation.
The wet air will be drawn into the machine and passed through the heat exchanger. So the moisture in the air will be condensed into water on the condenser and dry air will be released out of the dehumidifier. 

The principle of refrigerant.

High pressure refrigerant liquid enters into the evaporator after throttling by capillary. The refrigerant is evaporated as low temperature and low pressure gas by absorbing thermal from air after heat exchange. The low temperature low pressure refrigerant gas is inhaled into the compressor, after compressor compressing, the gas become high temperature high pressure refrigerant gas and get into the condenser. Then the refrigerant gas get into the condenser, after heat dissipation, the refrigerant gas become high pressure refrigerant liquid. Above is a complete cycle of refrigerating after repeating.
