COOLING VALVE COMBINATION LK G25M COLLECTOR G20M INSULATED
The LK 322 FreeCool Unit is a pre-insulated valve assembly that allows the cooling unit to be connected to the collector loop of a ground-source heat pump system equipped with a borehole.
When the collector loop's circulating fluid is utilized for cooling, you can cool your home using the naturally cold fluid in the collector loop. At the same time, the borehole is recharged during summer, improving the heat pump's efficiency.
The LK 322 FreeCool Unit includes a check valve to ensure the fluid flows in the correct direction when the cooling circuit is equipped with its own circulation pump. A suitable pump group is the LK Hydronic Group.
The LK 322 FreeCool Unit has two G20 outlets equipped with ball valves for connecting the cooling unit and two connections for the collector loop pipes.
