Documents

  • pre-assembled, tightness-tested and heat-insulated assembly
  • with high-grade, robust mixer
  • Version with adjustable flow coefficient Kvs from 2.5 to 12 m3/h: Adjustment also possible during operation (under pressure) at any time
  • available with high energy efficiency pump class A

Heating pump assembly for use in mixed heating circuits. With the 3-way mixer and the actuator, the flow temperature can be adjusted to a desired temperature by adding water from the return. The mixer version with adjustable flow coefficient Kvs offers maximum flexibility in adapting the system to individual control requirements. The flow coefficient Kvs can be modified at any later point in time, even if the system is under pressure. This way, a great variety of mixer/pump assemblies can be covered with a single version.

Comact, pre-assembled and tightness-tested heating pump assembly with all required functional components, form-fit heat insulation (complies with German Energy Saving Regulation) and wall mounting unit. Adhesive labels with pictograms allow for easy designation.
The flow line consists of:
Combination valve with thermometer in the hand wheel (red mark, range 0/120 °C)
3-way mixing valve with ProClick adapter system, either ARV 325 with flow coefficient Kvs 12 m3/h or KVS Vario with adjustable flow coefficient Kvs
Maintenance-free, silent actuator ARM 343 (6 Nm, 120 s, AC 230 V) with 0/90° angle of rotation, indication for direction of rotation, selector key "Manual/Automatic Mode" and ProClick adapter system
System connection G1½ male (boiler), G1 female (heating circuit) Suitable for pumps DN 25 with G1½ x 180 mm.
The return line consists of:
Combination valve with gravity brake, thermometer in the handle (blue mark, range 0/120 °C)
Pipe for length compensation as T piece for mixer connection with screw connection for system connection
System connection G1½ male (boiler), G1 female (heating circuit)
