Hydraulic tower 300 litres

HPK 300
HPK 300
  SG Ready

The hydraulic tower enables fast and simple connection of a heat pump for heating purposes to a heating system with an unmixed heating circuit. The following components are mounted in a space-saving way and wired ready to use:

  • Buffer tank 300 l with integrated screw-in radiator 6 kW and the option of integrating an additional immersion heater (up to CTHK 634).
  • Electronically regulated circulating pump wired ready to use for unmixed heating circuits (consumer circuit)
Auxiliary circulating pump for generator circuit and domestic hot water preparation.
  • The hydraulic isolation of the generator circuit and the consumer circuit is carried out via two differential pressureless manifolds (bypass pipes), which are each fitted with a check valve.
To reduce the runtimes, the unregulated auxiliary circulating pump in the generator circuit is only operated when the compressor is running and when there is a risk of frost. The uniform flow through the buffer tank connected in series extends the runtimes of the compressor and ensures the required heating water flow rate in all operating modes. Delivered complete with 5 m connection cable, pre-wired on the hydraulic tower and labelled on the free cable ends for easy connection to the heat pump manager.
