Calorex DD 1300 Dehumidifier

The Calorex DD 1300, 2300, and 3300 are a series of three compact high capacity dehumidifiers offering continuous range of air flows, insulated casing and advanced PLC controls suitable for both commercial and industrial applications.

This series of dehumidifiers are designed to be used in both standard and close control scenarios, making them a versatile option for a wide variety of applications. They have many optional features which can tailor them to specific requirements including energy saving and demanding control requirements. The insulated stainless steel construction also allows them to be used where hygiene is an important requirement and where precooling or lower process temperatures are required.

This range can be used for drying air up to 100% relative humidity with temperatures from -30°Cto +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.
