AD 3000-6500 Industrial Dehumidifier
Desiccant Rotor
Silica gel rotor adsorption dehumidifiers designed for high-capacity industrial facilities, large production areas and critical process environments. AISI 304 stainless steel housing, electric and steam regeneration options, PLC control with touch-screen display.

Adsorption Technology
AD series units operate on an adsorption principle using two separate air streams. Process air passes through the silica gel rotor; the silica gel absorbs water vapour from the air, drying it. As the rotor slowly turns, regeneration air is directed in the opposite direction: heated to +100°C by electric heaters, this airstream strips the absorbed moisture from the rotor, restoring its initial adsorption capacity. The moisture-laden regeneration air is then discharged to the outside.

Humid air passes through a G4 filter and is directed to the silica gel rotor; the fan drives the airstream using negative pressure.
The silica gel rotor adsorbs water vapour from the process air; the dried airstream is delivered to the process or conditioned space.
PTC electric heaters raise regeneration air temperature to ~100°C; this hot airstream passes through the rotor in the opposite direction, stripping and expelling moisture.
The rotor slowly rotates between adsorption and regeneration zones, providing uninterrupted dehumidification.
Materials & Structural Features
AISI 304 stainless steel; removable top and front panels for easy maintenance.
High-efficiency silica gel rotor; low air pressure drop, long service life and consistent adsorption capacity.
Gearmotor and belt drive system; stable operation at 6–12 rph.
Electric: steel element star-connected heating coil; 2, 3 or more sequential stages for power modulation. Steam (optional): AISI 304 stainless steel tube steam coil with modulating 2-way valve.
Process and regeneration fans directly coupled to IP55 / ISO F class single or three-phase motors; optional frequency converter for speed control.
Separate G4 filters on both process and regeneration air inlets; optional F5/F7/F9.
PLC control with touch-screen display; regeneration temperature regulation, alarm management, RH/dew point control and BMS integration.
Standard spiral duct compatible connections; process air inlet, dry air outlet, regeneration air inlet and wet air outlet.
