Desiccant Dehumidifiers: DL Range
DL35 Industrial Desiccant Dehumidifier
The DL35 is our highest-capacity compact model, engineered for large dry rooms, pilot plants, and cleanroom environments. Its high-performance silica-gel rotor with integrated purge-sector heat recovery provides continuous, condensate-free dehumidification. A Siemens touch-panel HMI gives live insights into humidity, temperature, rotor health, and energy use-enabling proactive maintenance and seamless integration into building-automation systems.
