Condensing Units

The ideal supplement to our air-handling units

Whoever depends on air-handling units with direct evaporation systems can find the best solution among the DencoHappel condensing units. The condensing units are connected via refrigerant tubes to an evaporator in the air handling unit. Therefore additional buffer tanks, water pipework, frost protection and pumps are not required.

Depending on the series, the units can not only provide cooling, but are also designed for the monovalent heating operation. The refrigerant circuit is reversed via an integrated 4-way valve, and the evaporator in the air-handling unit works as a condenser. This way a single unit can provide not only cooling but also heating all year round.
