Efficient radial fans

Direct-driven AC and EC fans, supplied by leading manufacturers with premium efficiency, ensure reliable long-term operation. On the DA 400 and DA 450, the EC fans can be speed-adjusted via a potentiometer, allowing airflow adjustment and, additionally, modulation of the dehumidification capacity based on demand from an external humidity controller.

Compact & efficient

The Condair DA 210-450 unit features a compact, corrosion-resistant stainless steel housing with dedicated circular duct connections for process and regeneration air, and a plug-and-play 230 V power cable. The high-performance desiccant rotor has a honeycomb fibreglass structure coated with highly hygroscopic silica gel, providing efficient, maintenance-free moisture transfer while being non-flammable.

PTC-reactivation heater

The Condair DA 210-450 uses a PTC reactivation heater, whose self-regulating characteristics prevent overheating by adjusting internal resistance and current consumption based on temperature. This ensures safe, reliable rotor regeneration and improves operational reliability. The integrated ampere meter simplifies commissioning and monitoring, enabling quick and accurate verification of heater performance.

Functional principle

Dehumidification occurs through the adsorption of the water vapour contained in the humid air on hygroscopic surfaces (silica gel rotor).

Frequently asked questions

What are the drying capacities and airflow rates of the Condair DA 210–450 units?

The Condair DA 210–450 series provides the following drying capacities, at 20 °C and 60 % relative humidity.
DA 210: Drying capacity 0.6 kg/h, process air 210 m³/h, regeneration air 40 m³/h
DA 400: Drying capacity 1.5 kg/h, process air 400 m³/h, regeneration air 120 m³/h
DA 450: Drying capacity 2.2 kg/h, process air 450 m³/h, regeneration air 120 m³/h
All units function efficiently across a wide temperature and humidity range, including negative temperatures, as long as the dehumidifier is placed in an environment with similar ambient conditions. The high-performance silica gel rotor ensures effective and efficient dehumidification even at low temperatures.

What operating modes and control options are available on the Condair DA 210–450?

The Condair DA 210–450 units are designed for simple and reliable operation and do not have a built-in PLC. They can run in Manual Mode, operating continuously at full capacity, or in Auto Mode, when controlled by an external hygrostat, humidity controller or building management system. The DA 210 supports on/off control via a hygrostat, while the DA 400 and DA 450 can also be modulated by an external dehumidification capacity signal (0–10 V), allowing precise adjustment of performance to actual dehumidification demand.

What safety and maintenance guidelines should users follow for the Condair DA 210 - 450?

Users should regularly maintain theirCondair DA 210 - 450 desiccant dryers to ensure safe, reliable operation. Check and clean air filters at least monthly during the first year, inspect the rotor, bearings, and drive belt annually, and monitor heaters and seals every six months. Never operate without filters, avoid chemical exposure to the rotor, and verify motors and fans for proper function to preserve performance and longevity.
