Dehumidifier DR-20B-30D

Product catalog summary

Overview: The Dehumidifier Recusorb models DR-20B and DR-30D are designed with a washable rotor, protected control panel, stainless steel chassis, self-regulating heater, and a fold-flat handle for easy transport. These features contribute to a long lifetime and easy maintenance, including accessible filters.

Specifications:

Dehumidifying capacity at 20°C / 60%RH: 0.8 - 1.1 kg/h
Dry air flow: 330 - 360 m³/h
Wet air flow: 60 - 75 m³/h
Heater current: 4.5 - 6.5 A
Maximum electric consumption: 1.2 - 1.7 kW
Supply fuse: 230V / 50Hz, 10 A
Weight: 15 - 17 kg

Technical Details: The dehumidifying capacity is calculated using a correction factor from a diagram for different inlet conditions. The PTC heater design allows power regulation by controlling wet air flow. The temperature of the dry air at nominal air flows is calculated with specific formulas for each model.

Design Features: The rotor section from Seibu Giken features a high number of channels for efficient moisture adsorption. The unit includes a process air fan, heater, rotor motor, and designated outlets for dry and wet air.
