Calorex DD 1100 Dehumidifier

The Calorex DD 800 and 1100 are designed to be used in a wide variety of commercial and industrial applications. They have optional features which can tailor them to specific requirements. The energy saving and control options make these dehumidifiers ideal for continuous process applications and where close control is a requirement. The stainless steel construction also allows them to be used where hygiene is an important requirement.

This range can be used for drying air up to 100% relative humidity with temperatures from -30°C to +40°C. Suitable applications include: production processes, condensation control, equipment preservation, climate control in storage areas, food, beverage and confectionery production, cold storage, drying processes, and climate control in buildings and specialised production areas.
