Heat circuit groups
HKG & HKGM 25/32

The heat circuit groups take over the heat distribution for the house.

There are pure pump groups HKG or “hot” groups for boiler loading or fans. The HKGM or heat circuit group mixers (mixed groups) are suitable for floor heating or radiators.

They are available in sizes DN25 and DN32 and in versions with and without mixer with servomotor.

HKG – heat circuit group 25 bzw. 32
HKGM – heat circuit grop with mixer 25 bzw. 32

Furthermore, there are two different distributors available for each dimension (DN25 / 32) for two, three and four heat circuit groups. Installation is on the wall or directly on the accumulator using the accumulator mounting plate.
