Rotary desiccant wheel units engineered to maintain 15–50% RH in warehouses, cold storage, labs, and process rooms—OEM/ODM, sealed cabinet construction, energy-efficient control.
We design rotary desiccant wheel dehumidifiers to keep critical spaces at a stable 15–50% RH. Standard units integrate with existing HVAC for temperature control and are widely used in warehouses, cold storage, and laboratories. Airflow options cover 320–10,000 m³/h with multiple moisture-removal ratings to match your process and footprint.

Reaches target RH in cold rooms and winter conditions—operating −10 to +50 °C (14–122 °F) where refrigerant dehumidifiers ice up.
Drying performance depends on rotor speed and regeneration heat, not room temperature—ideal for packaging, storage, and process lines.
Ductable “dry air” with no condensate handling; easy tie-in to existing HVAC/BMS and straightforward service.
| Criteria | Rotary Desiccant (Non-Compressor) Dehumidifier | Compressor (Condensation) Dehumidifier |
|---|---|---|
| Working principle | Adsorbs moisture on a desiccant wheel; heat regenerates the rotor. | Cools air across a refrigerant coil to condense water. |
| Best RH range | ≥35-45% RH and tight control at low dew points. | 40-60% RH; struggles below ≈40% RH. |
| Condensate handling | No drain needed (no liquid water produced). | Requires drain/pump for condensate. |
| Energy efficiency profile | Higher kWh/kg at moderate RH, but best choice for low RH or low-temp environments. | Most efficient at 20-30°C and 40-60% RH. |
| Typical applications | Cold storage, pharma/food packaging, electronics drying, lithium-free dry rooms, process rooms. | Warehouses at moderate RH, general comfort drying, basements, water-damage restoration. |
Rotary desiccant dehumidifiers deliver stable 15–50% RH and tie into existing HVAC where temperature control is required—ideal for warehouses, cold storage, and laboratories. Airflow options span 320–10,000 m³/h with moisture-removal steps up to 64.8 kg/h for precise sizing.

Straight answers on sizing, operating range, power, controls, and after-sales—so your team can evaluate quickly and specify with confidence.
Our rotary desiccant lineup covers 3.0–57 kg/h moisture removal with process airflows from ≈320 to 4,500 m³/h, allowing precise matching to room size and target RH.
Models are designed for −10 to +50 °C operation; small/medium frames specify −5 to +50 °C—suited to winter conditions and cold rooms where refrigerant units struggle.
Smaller units run on 220 V/50 Hz (e.g., RW-600M 4.5 kW), while larger frames use 380 V/50 Hz (e.g., RW-1000M 11 kW, RW-4500M 50 kW).
Each unit includes a PLC controller for stable operation, access-door design for quick service, G4-grade filters, rotor auto-stop, and delay-time protection with fault locator.
Systems use electric regeneration heating at 110 ± 10 °C; equipment ships in a wooden case with a 1-year warranty and washable rotor designed for a 5-year lifetime.
