High-Performance desiccant rotor

The desiccant rotor consists of a honeycomb structure made of fibreglass, coated with highly hygroscopic silica gel. The flutes provide an enormous internal surface area, enabling efficient and effective moisture transfer. The rotor material is non-flammable and non-respirable and are largely maintenance-free.

Quiet, efficient, reliable

The Condair DA 4400–12000 range features a fully insulated, double-walled Magnelis® housing with 30 mm mineral wool for quiet, efficient operation. Optional AISI 304 stainless steel casings are available. Premium EC 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 4400–12000 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.

Frequently asked questions

What accessories and customisations are available for the Condair DA 4400–12000 units?

The Condair DA 4400–12000 series offers a wide range of customisations to meet 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, and full modulating capacity control. Alternative reactivation heating sources, such as steam, hot water, or a combination with electrical reactivation, can be used to reduce operating expenses. Additional options include stainless steel housing, outdoor installation, potentiometers for EC fans, heat recovery modules, humidity and temperature sensors and Modbus TCP/IP, RTU, or BACnet connectivity.

What are the capacities and operating ranges of the Condair DA 4400–12000 series?

The Condair DA 4400–12000 series provides the following nominal drying capacities at 20 °C and 60 % relative humidity:
DA 4400: Drying capacity 28 kg/h, process air 4 400 m³/h, reactivation air 1 200 m³/h  DA 6400: Drying capacity 36.5 kg/h, process air 6 400 m³/h, reactivation air 1 600 m³/h  DA 7400: Drying capacity 45 kg/h, process air 7 400 m³/h, reactivation air 2 250 m³/h  DA 9400: Drying capacity 54 kg/h, process air 9 400 m³/h, reactivation air 2 500 m³/h  DA 12000: Drying capacity 63 kg/h, process air 12 000 m³/h, reactivation air 2 500 m³/h
All units operate reliably across a standard range of 0–40 °C and 0–100 % relative humidity. Units can be modified for lower temperatures or outdoor installation, ensuring effective dehumidification in almost all conditions.

What control options are available on the Condair DA 4400-12000?

The Condair DA 4400–12000 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.
