The LK 322 CoolUnit is a valve combination for geothermal

heat pumps that channels cold brine to a fan coil, cooling

your home with natural ground cold. It also recharges the

borehole in summer, improving heat pump performance.

With a non-return valve for proper flow and flexible 1” or

11⁄4” collector and 3⁄4” convector connections, it offers an

efficient, versatile free cooling solution.
