These GCH condenser units are the ideal cooling solution for direct-evaporators in central air handling units. The units are switchable and can also be used in heating mode.
Space-saving optimized design (1 or 2 scroll compressors)
Heat pump circuit with 4-way valve for cooling ór heating operation
Compressor controlled by inverter technology
Cooling operation from 43 °C to -5 °C - Outside temperature (Dry ball)
Heating operation from 15.5 °C to -20 °C - Outside temperature (wet bulb)
Control over constant evaporation and condensation temperatures or via 0-10 volt signal provided by the customer
Accessories: expansion valve kit GZCH ... CD.R12 and communication box GZCH-3BOX.E15
The condenser units are connected via refrigerant lines to an evaporator in the fan unit. Therefore, additional buffer tanks, water pipes, frost protection and pumps can be dispensed with.
Depending on the series, the units can not only cool, but are also designed for monovalent heating operation. The refrigerant circuit can be reversed via an integrated 4-way valve, and the evaporator in the centrifugal fan operates as a condenser. This means that with just one appliance, it is also possible to cool and heat all year round.
