High-performance desiccant rotor

The desiccant rotor consists of a honeycomb structure made of fibreglass, coated with highly hygroscopic silica gel. Its flutes provide a vast internal surface area for efficient and effective moisture adsorption. Silicone-free, non-flammable, and largely maintenance-free, it is paired with self-regulating PTC heaters that prevent overheating and ensure safe, reliable operation without the risk for thermostat cutouts.

Quiet, efficient, reliable

The Condair DA 500–4000 range features a fully insulated, double-walled Magnelis® housing with 30 mm mineral wool for quiet, efficient operation. Optional AISI 304 stainless steel or uninsulated Compact versions are available. Premium radial fans in push configuration move regeneration and process air over the rotor under positive pressure, ensuring reliable operation even at very low humidity.

Tailored drying solutions

The Condair DA 500–4000 range adapts to your drying needs, offering PLC with touch screen, pre- and post-cooling, full modulating capacity control, heat recovery and electrical or steam regeneration. Special configurations for extremely low dewpoints are possible. Network integration via Modbus or BACnet ensures seamless industrial or commercial operation.

Reliable Push Fan

The push fan configuration enhances reliability by keeping the regeneration fan away from humid, hot air, reducing strain and ensuring long-term stable operation.

Site-Adaptive Cooling Coils

Pre- and post-cooling coils can be mounted directly on the unit or in separate modules, adapted to site-specific requirements, enabling large dehumidification deltas in a single pass.

Safe Service Access

All critical components are easy to remove, filters are replaceable, and the vertical rotor design ensures low height, optimal load distribution, and high operational safety.

Frequently asked Questions

What accessories and customisations are available for the Condair DA 500–4000 units?

The Condair DA 500–4000 series offers a wide range of options to adapt to specific customer requirements. Available accessories include advanced PLC variants, pre- and/or post-cooling coils mounted on the unit or in separate modules, filter guards, full modulating capacity control and steam-powered reactivation. Additional options include stainless steel housing, outdoor installation, EC fan upgrades, potentiometers for EC fans, heat recovery module, humidity and temperature sensors, Modbus TCP/IP, RTU or BACnet connectivity and air-cooled condensation modules.

What are the capacities and operating ranges of the Condair DA 500-4000 units?

The Condair DA 500–4000 series provides the following drying capacities at 20 °C and 60 % relative humidity:
DA 500: Drying capacity 3.3 kg/h, process air 500 m³/h, regeneration air 150 m³/h
DA 700: Drying capacity 5.1 kg/h, process air 700 m³/h, regeneration air 220 m³/h
DA 1000: Drying capacity 7.1 kg/h, process air 1000 m³/h, regeneration air 350 m³/h
DA 1400: Drying capacity 10.0 kg/h, process air 1400 m³/h, regeneration air 400 m³/h
DA 2400: Drying capacity 13.5 kg/h, process air 2400 m³/h, regeneration air 500 m³/h
DA 3400: Drying capacity 14.5 kg/h, process air 3400 m³/h, regeneration air 550 m³/h
DA 4000: Drying capacity 20.0 kg/h, process air 4000 m³/h, regeneration air 850 m³/h
All units have a standard operating range of 0–40 °C but can be modified upon request for lower temperatures or outdoor installation. This ensures reliable operation across a wide temperature and humidity range, together with the high-performance silica gel rotor, in almost all circumstances.

What control options are available on the Condair DA 500-4000?

The Condair DA 500–4000 units are equipped by default with a PLC with touchscreen. The PLC controls all internal processes, including alarm and service management. A moisture sensor can be connected to enable the unit to control humidity independently. Alternatively, dehumidification capacity can be controlled via a humidity controller or an external building management system using on/off or 0–10 V / 0–100 % capacity control. More advanced PLC options are available, which can also regulate the temperatures of cooling coils. Connectivity with building management systems via Modbus (TCP/IP or RTU) or BACnet is also available.
