Industrial drying – adsorption

Ideally suited for dehumidification tasks where space is limited, this range of small air flow desiccant dehumidifiers is characterised by its high performance due to two air inlets, two air outlets and two fans as well as robustness due to the insulated stainless-steel cabinet.

The dehumidifier range is suitable for several fields of application, in particular where space is limited. The stainless-steel housing with corrosion resistance class C5-I makes the units ideal for both hygienic and aggressive environments.

 

Thanks to their wide range of sizes and ability to operate between -20° and +40°C, the DRD desiccant dehumidifiers are ideal for complex humidity regulation. They offer extremely efficient humidity control for a wide range of industrial processing, food industry, pharmaceutical and similar challenging applications.

Technology

The DRD desiccant dehumidifiers operate through moisture absorption by means of a rotor-reinforced composite on which absorbing elements are permanently fixed. Capable of creating dew points as low as -60°C, this rotor drying technology makes the dehumidification process very effective even under extreme conditions (-20°C/+40°C). It also ensures a continuous dehumidification process, with expulsion of the humid air to the outside without having to remove condensed water. Moreover, when required, the rotor can be washed without altering its operating characteristics.

Electrical control and command

The electric control panel is complete with electrical wiring for power supply voltages at 400Vac 3Ph + PE and 230Vac 1Ph+N for the smaller sizes.

The panel comes equipped with Power On command and a voltage transformer for auxiliary circuit control. The contactor-initiated fan motors for process and reactivation are of the EC type. They have been fitted with magneto-thermal protection and they can be reset manually. Regulation and control of the unit is handled by a microprocessor board for optimal performance. The controller comes equipped with RS 485 and/or TCP/IP connections.
