Industrial Refrigerant Dehumidifier
A self-contained condensation dehumidifier that cools process air below its dew point, drains the collected water and reheats the dry air through the condenser.
- Refrigeration Moisture Removal
- Automatic Hot-Gas Defrost
- Continuous Condensate Pumping
- Digital Humidity Control
Product Introduction
The industrial refrigerant dehumidifier combines a washable inlet filter, direct-expansion evaporator, compressor, condenser and centrifugal fan in one wheeled cabinet. Moist air condenses on the cold evaporator, then passes over the condenser so the discharged air is dry and slightly warmer. A built-in controller, hot-gas defrost and pumped drain support unattended humidity control in clean production and support spaces operating above typical refrigeration frost limits.
Key Features
Hot-gas defrost clears evaporator ice during low-temperature operation without relying on a long passive thaw cycle.
A condensate pump lifts collected water to a remote drain where gravity fall is unavailable.
Two-stage fan control and an external humidistat input allow the unit to match changing room moisture loads.
Customer Product Concerns
Moderately humid rooms need dependable water removal without the regeneration heat and dual air streams required by a desiccant system.
Seasonal humidity repeatedly rises above the acceptable range during production hours.A dedicated refrigeration circuit removes latent load independently of the room cooling thermostat.
The evaporator can ice when inlet air temperature falls during overnight operation.Automatic hot-gas defrost redirects refrigerant heat to the coil and restores airflow quickly.
A full condensate tank stops portable dehumidifiers when no operator is present.A float-controlled pump sends condensate through a hose to the building drain for continuous operation.
Dust accumulation on the cold coil reduces moisture removal and raises energy use.A front-access washable prefilter protects the evaporator and can be removed without opening the refrigeration compartment.
Typical Applications
Cleanroom support corridors and gowning areasMedical-device packaging roomsPharmaceutical raw-material storesElectronics assembly rooms with moderate dew-point targetsControlled warehouses and archives
