Dantherm DRD 120-163-235-358 – adsorption dehumidifiers
This range of medium air flow and high-capacity desiccant dehumidifiers has been designed with an insulated stainless-steel casing for maximum robustness and with the regeneration inlet and outlet placed on the same side to simplify installation. The units are very suitable for several fields of application, including those that offer limited installation space. The stainless-steel used is corrosion resistance class C5-I, thus making the desiccant dehumidifiers ideal for both hygienic and aggressive environments.
Delivered with an advanced user interface and fully ready for site installation, the dehumidifiers need only be connected ducting before they are ready for operation.
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.
Functions
The functions related to the control panel are:
- Regeneration air temperature control
- Management of manual or automatic operation via the external humidistat (optional)
- Safety thermostat electric heater element with regeneration release to launch voltage magneto-thermal protection
- Regeneration cool down timing
- Reporting to display unit status and alarms
- Pre and post cooling or heating temperature control (optional)
Construction specifications
The DRD range have been designed with a sturdy self-supporting base and structure with sandwich panels. All panels are insulated on the inside with a 25mm layer of mineral wool.
