Pump group for heating and cooling

Heating and cooling circuit in just ONE pump group with the PAW CoolBloC

The PAW CoolBloCs are pump groups which are used for heating as well as for cooling. They contain special valves and fittings and a special pump for the use in special ambient conditions which can occur during cooling and heating, such as dewing or condensate formation.

Heating technology in combination with cooling function

The innovative CoolBloC combines the proven heating technology of PAW with a cooling function.

  • The CoolBloCs are available in the nominal diameters DN 25 and DN 32 and are adapted to special ambient conditions.
  • All components are, within one pump group, perfectly designed for the requirements during heating and cooling.
  • The combination with a heat pump and the PAW domestic hot water module offers the ideal solution for your heating system!

Advantages of the combined heating and cooling circuits

  • only one pump group for heating and cooling
  • condensation-resistant valves and fittings: high-quality components to avoid oxidation
  • special pump with additional insulating element for the use in special ambient conditions
  • thermal separation of the actuator and the mixing valve to avoid condensate formation
  • sealing lips protected by the utility model in the insulation to reduce condensate formation
  • available as direct or mixed type

CoolBloC pump group functioning:

Heating – Application during the winter:
  • A heat sink (e.g. a heat pump) provides cooled fluid.
  • The cooling circuit transports the cooled fluid to the interior spaces.
  • There, a heat transfer takes place and the fluid is heated.
  • The heated fluid is cooled down again in the heat sink.
Cooling – Application during the summer:
  • A heat source (e.g. a heat pump) provides heated fluid.
  • The cooling circuit transports the heated fluid to the interior spaces.
  • There, a heat transfer takes place and the fluid is cooled down.
  • The cooled fluid is heated again in the heat source.
