Compact desiccant dehumidifiers for cold and low-humidity spaces where refrigerant units lose efficiency. They dry the air with an adsorption rotor rather than condensation — working below freezing, reaching very low target humidity, and needing no condensate drainage. Quiet enough for occupied rooms, archives and laboratories.

Applications

Cold storage
Server rooms
Archives & museums
Small pharma rooms
Restoration
Specialty manufacturing

Key features

Adsorption (desiccant) dryingworks below freezing and down to very low RH where condensation units cannot
No condensate drainagemoisture is carried out on the regeneration airstream — no condensate to plumb
Single-phase supplystandard 220–230 V outlet; compact cabinet for tight installations
Ducted by designprocess and regeneration ducts attach to the cabinet, integrated into the room air layout
Quiet operationfrom < 45 dB(A), suitable for occupied rooms, labs and archives
Dual-fan designseparate process and regeneration fans for maximum drying efficiency
