GPE... Series
One or two refrigerant circuits  - cooling capacity from 34 to 170 kW

POLYVALENT UNITS R407C – R22
HEAT PUMP WITH 4 PIPES
WITH SCROLL COMPRESSORS

"The units can be installed in all the applications where there is the need to produce at the same time cold and warm water. The peculiarity of this ""Polyvalent Groups"" is to suit all the needs of the moment, independently from weather conditions.
These units are 4-pipes heat pumps with separate and not interchangeable circuits, supplied with an additional water/refrigerant condenser/recovery on each cooling circuit, able to entirely replace the air/refrigerant condensing coil and to produce ""free"" warm water, when needed.

RUNNING MODES

• MODE 1: Only Cooling Mode
  When the warm water production is not required, the unit runs as a water chiller and produces only cold water. With such a running mode and in order to complete the cooling process, the evaporator and the condensing coil with air-cooled fins are the exchangers in use.
• MODE 2: Cooling Mode with heat recovery
  When warm water is required as well, the unit can operate as water chiller with heat recovery and produce warm water at the same time, without additional costs and exploiting the heating power of the condensing process. With such a running mode and in order to complete the cooling process the evaporator and the condenser/recovery (which is water-cooled and where the condensing process takes place) are the exchangers in use.
• MODE 3: Heat Pump Mode
  The unit runs as an heat pump and therefore produces warm water. With such a running mode and in order to complete the cooling process, the finned condensing coil (as evaporator) and the condenser/recovery (which is water-cooled and where the condensing process takes place) are the exchangers in use.

On units with 2 circuits, it is possible to have all the above mentioned running modes at the same time on different circuits (i.e. the circuit 1 can be on Mode 1 and the circuit 2 can be on Mode 2 or 3).
