Overview

The modular desiccant wheel dehumidification unit provides continuous moisture removal for applications where a cooling coil alone is not sufficient. Process air passes through a slowly rotating desiccant medium, which adsorbs water vapour before the drier air leaves the treatment section.

A separate heated regeneration airstream removes the retained moisture from another zone of the wheel and carries it outdoors. As the wheel rotates between the process and regeneration zones, adsorption and regeneration continue as a repeating cycle. This arrangement allows moisture control to be coordinated with the required supply-air temperature.

The catalogue includes basic and combined units, with optional filtration, pre-cooling, post-cooling and mixing sections. Electric or steam regeneration can be selected according to the available utilities and project operating strategy.

PRODUCT DETAILS

Product Features

Continuous desiccant process

The rotating moisture-adsorbing medium moves between treatment and regeneration zones. This provides ongoing drying instead of relying on a material that must be removed and replaced after every operating cycle.

Separate regeneration circuit

A dedicated fan and heater supply regeneration air to remove moisture from the wheel. The regeneration airflow, heat source and exhaust route are designed together with the process-air duty.

Modular treatment arrangement

Pre-cooling, post-cooling, filtration, fan and mixing sections can be combined around the moisture-control section. This allows the unit to address temperature and humidity as related design requirements.

Choice of regeneration heat

The catalogue lists electric and steam heating options. The appropriate arrangement depends on the site’s utilities, regeneration duty, operating hours and the selected equipment configuration.

Insulated cabinet construction

An aluminium-alloy frame and double-skin insulated panels support the modular assembly. Thermal-bridge control and a sealed wheel arrangement help manage unwanted heat transfer and air bypass.

Optional monitoring and controls

PLC control and selected alarms can support fan, heater and rotor operation. Options include humidity control, rotor-stop or filter alerts, remote operation and monitoring of selected temperatures.

WHERE IT WORKS

अनुप्रयोगों

The catalogue identifies electronics production, precision-instrument rooms, museums, libraries, storage and process drying as applications. More demanding low-humidity production requires a model and complete treatment arrangement specifically selected for that duty.

Confirm process airflow, entering conditions, target humidity, regeneration utilities and exhaust routing. Very low dew-point duties require a dedicated selection and should not be assumed from the general product description.
