Desiccant Dehumidifiers: DL Range
DL25 Industrial Desiccant Dehumidifier
The DL25 delivers mid-range capacity in a compact package. Its silica-gel rotor with built-in heat recovery removes up to 35 lb of moisture per hour without condensate or drains. The Siemens touch-panel HMI shows live humidity, temperature, rotor health, and energy use. Ideal for medium-sized dry rooms, pilot plants, and storage areas.
