LK 322 CoolUnit is a valve combination that utilises the cold

available in a system with a geothermal heat pump.

By running the brine in the collector hose to a fan coil, you can

cool your home with the cold naturally found in the ground. In

addition, the borehole is recharged during the summer, which

increases the performance of the heat pump.

The LK 322 CoolUnit also contains a non-return valve to ensure

the liquid is run in the right direction when fitting the shunt

group with its own circulation pump. See LK HydronicGroup

C/C 90 and 125 Cooling for a suitable shunt group.

The LK 322 have two 1” alt. 11⁄4” male thread for connection to the

collector pipe. Two ball valves with 3⁄4” male thread for connection

to convector pipe.
