HRC CASCADE Z1 • Cascade high temperature air/water heatpump 70°C

HRC70 air/water heat pumps in cascade are suitable for high water temperatures. Monoblock with natural refrigerant propane (R290) for water heating up to 70°C. The unit guarantees proper operation down to -20°C outside temperature.
The HRC70 is a single heating unit that uses 2 scroll compressors with different capacities and with a soft starter as standard. This ensures 3 power stages and low power consumption. Due to the special construction, the unit will have to defrost less often and the defrost cycle will be completed as efficiently as possible.

The unit maintains its high COP values even at negative outside temperatures. Possibility to link 3 HRC70 units with a total power of 96kW.

Composition

Outdoor: Two or three monoblock heat pumps HRC70 25 or 32 for cascade installation.
Included with each outdoor unit:

  • 10 m long bus cable for communication between the HRC70 and the Pilote Z1 (3 core and already connected to each HRC70) (do not place in parallel with power cable).
  • Flexible pipes (Durite) of 1.5 m long and rigid insulated pipe to indoor module (diameter according to distance between the two, see table at the bottom of this page).
  • Filter 1"1/4 for placement on the return connection.
  • 2.5 bar pressure relief valve mounted in the HRC70.
