6 models from 7 to 15kW Water rating 40/45°C in Heating mode (7/12°C in Cooling mode) Refrigerant R410A The best COP on the market; the lowest sound levels on the market Complete hydraulic equipment incorporated Electronic control system Operating limits: T outdoor air: -15°C in Heating mode (43°C in Cooling mode)

• Heat Pumps conceived for the production of hot water for heating and the production of cold water for air-conditioning.
• Conceived for an optimal operation in water rating 40/45°C in Heating mode and 7/12°C in Cooling mode.
• Compact units to be installed outside.
• Ozone friendly refrigerant R410A for the respect of the environment.
• Very high coefficients of performances, leading to a very important reduction of the energy consumption.
• High quality composants: Scroll compressor with sound insulation; high performance heat exchanger with fins for R410A; axial fan motor; heat exchanger with AISI 316 stainless steel plates and heat insulation, etc.
• Silent operation: the PHRT Heat Pumps have the lowest sound level on the market.
• Units ready to operate, with hydraulic equipment incorporated : single start-up kit (PHRT7-9-12 single-phase)3-speed circulating pump, expansion tank, safety valve, air bleed valve, water pressure control, hydraulic filter.
• Complete equipment: the PHRT Heat Pumps are equipped with the following safety systems: high and low pressure switch, water flow switch, anti-freeze safety.
• Electronic control by microprocessor (with keypad) which optimizes the operation of the Heat Pump and grants the following functions:
  • Temperature control of hot water and cold water
  • Proportional head pressure control
  • Automatic control of the circulating pump (anti-freeze and anti-seize fonction)
  • Defrosting adjusted according to the outdoor temperature
  • Alarm management by means of event logging
  • Counting of the operating time of compressor and circulator
  • External communication via a serial inerface (Protocol Modbus) (accessory)
• Other advantages: :
  • Keypad/display fitted to the front panel to make it easy the start-up and maintenance
  • Dividing bulkhead between the fan and the machinery compartment
  • Option of removing the "control" panel for a wider opening
  • Stringent manufacturing inspections : helium waterproof test, di-electrical and electrical test, hydraulic test, ...

The Heat Pumps PHRT 9-12-16-18 are certified by EUROVENT and compliant with PROMOTELEC requirements; they meet the criteria recommended by the AFPAC (Association Française pour les Pompes à chaleur), member of the EHPA (European Heat Pump Association) for the EC Countries.

Available accessories

• SINGLE START-UP KIT (for single-phase only  PHRT 9-12):
  It allows to reduce the starting current of the compressor of the Heat Pump PHRT and to respect the standard NFC 15-100 (included in the conditions of Promotelec program)
• ANTI-FREEZE KIT: this electric resistance kit avoids the formation of ice (due to condensation) on the lower part of the heat pump in winter.
• HYDRAULIC CONNECTION KIT BETWEEN PHRT and ADDITIONAL ELECTRIC HEATER MODULE MC8/10: this kit makes it easy to do the connetion between the Heat pump and the additional electric heater when this one is installed directly on the heat pump.
• FLEXIBLE WATER PIPES: makes it easy the hydraulic connection between  the Heat Pump and the network
• REMOTE CONTROL KEYBOARD AND DISPLAY
• ADDITIONAL TANK:  to be added if the installation water volume is particularly low, in order to avoid an operation in short-cycle of the heat pump (consult us)
