Dehumidifier with Air Recirculating and Heat Pump Function 

Type CAU 

Functional description of the unit 

The GEA CAIRfricostar CAU is mainly designed for private swimming pools and can 

be delivered in 4 sizes. The unit's function is to dehumidify and heat air in swimming 

pools in circulating air mode. The unit is supplied with a fully electronic control system 

that automatically regulates system functions. 

Operation mode with dehumidification demand 

In circulating air mode without dehumidification the air is recirculated in the swimming 

pool. The multifunction humidistat that is installed in the swimming pool switches the 

unit into dehumidification mode as soon as the humidity setpoint has been exceeded. 

At this point the fan is switched into speed 2 and the refrigeration circuit is activated. 

The dehumidification process is carried out until the setpoint is reached. After that the 

fan is switched into speed 1 and the circuit compressor is stopped. Using an optional 

pool water condenser a certain amount of excess energy produced by the heat pump 

cycle can be fed back into swimming pool water or similar circuit system. 

Air recirculating dehumidifier CAU 

Supply air fan runs at high speed. The necessary transmission heat is provided by the reheater coil. Using 

an optional pool water condenser a certain amount of excess energy can be fed back into swimming 

pool water.

Dehumidification unit with air mixing and heat pump function 

Type CMU 


The GEA CAIRfricostar CMU is designed for private and small public swimming pools. 

The series is available in 6 sizes. The unit's function is to dehumidify and heat air in 

swimming pools in air mixing mode. The unit is delivered with a DDC controls which 

regulates all functions of the system on a fully automated basis. 

When in idle mode without dehumidification the air is recirculated in the swimming pool. 

When the humidity setpoint has been exceeded the unit switches into dehumidification 

mode. At this point the supply air fan is switched into speed 2 and the exhaust air fan 

maintains air circulation at speed 1. The refrigeration unit is activated in order to start 

dehumidification. Using the bypass damper a certain part of return air is mixed without 

further treatment with dehumidified air that has passed through the refrigeration cycle. 

The dehumidification stage continues until the actual humidity value lies below that of 

the humidity setpoint. After that the fan is switched back into previous speed and the 

refrigeration cycle is stopped. 

When in active hours swimming pool mode the fresh and exhaust air dampers are 

opened, the bypass damper is closed. The dehumidification takes place via the activation 

of the refrigeration cycle with both fans switched into speed 2. 

Using an optional pool water condenser a certain amount of excess energy produced 

by the refrigeration cycle can be fed back into swimming pool water.

In case of overheating of the swimming pool and high outdoor temperatures 

the heat pump is blocked. The unit operates for ventilation 

and dehumidification in air mixing or only outdoor/exhaust air mode. 

The fans run at high speed. In case of an optional bypass of the heat 

recovery system the latter is not used thanks to a damper system. 

If the swimming pool is overheated during the night time or idle period 

the unit ventilates only in outdoor/exhaust air mode. The fans run at 

high speed and provide cooling of the swimming pool to reach the 

setpoint temperature.

Type CMP 



The GEA CAIRfricostar CMP is designed for various kinds High Performance private 

and public swimming pools. The series can be supplied with air volume capacity 

between 750 up to 37,500 m³/h. The unit's function is to dehumidify and heat air in 

swimming pools in air mixing mode. Together with a (heat pump) this unit type is additionally 

equipped with an efficient heat recovery system using a double plate heat 

exchanger. The unit is delivered with a DDC controls which regulates all functions of 

the system on a fully automated basis. 

Sample selection of operation mode: 



mode. At this point the supply air fan is activated and the exhaust air fan maintains the 

air circulation. The refrigeration unit is activated in order to start dehumidification. The 

dehumidification stage continues until the actual humidity value is reduced below that 

of the humidity setpoint. After that the fan is switched back into previous speed and the 

dehumidification cycle is stopped. 

In active hours mode the fresh and exhaust air dampers are opened, the refrigeration 

cycle is activated and both fans are switched into high speed. 


by the refrigeration cycle can be fed back into swimming pool water. In case of overheating 

of the swimming pool the refrigeration unit is deactivated and the bypass 

dampers are permanently open in order to avoid heat recovery system.

Dehumidifier with Air Mixing Function 

Type CWR 


The GEA CAIRfricostar CWR is designed for various kinds of private and public swimming 

pools. The series can be supplied with air volume capacity between 750 up to 

45,000 m³/h. The unit's function is to dehumidify and heat air in swimming pools in air 

mixing mode. This unit type is additionally equipped with an efficient heat recovery system. 

The unit is delivered with a DDC controls which regulates all functions of the system 

on a fully automated basis.

Dehumidification Unit with Air Mixing and Heat Pump Function 

Type CWC 


The GEA CAIRfricostar CWC is designed for private and small public swimming pools. 

The series is available in 2 sizes. The unit's function is to dehumidify and heat air in 

swimming pools in air mixing mode. The unit is delivered with a DDC controls which 

regulates all functions of the system on a fully automated basis. 

Sample selection of operation modes: 

This unit type is additionally equipped with an efficient heat recovery system. When in 

idle mode without dehumidification the air is recirculated in the swimming pool. When 

the humidity setpoint has been exceeded the unit switches into dehumidification mode. 

For this purpose the supply and exhaust air fans are activated to run at high speed with 

continuous mixing of outdoor air. The dehumidification stage continues until the actual 

humidity value lies below that of the humidity setpoint. After that the fans are deactivated.
