Air source brine collector module for use with flexoTHERM 400V

  • Very low noise output with 47 dB(A) sound power
  • Twin unit connection with balanced Tichelmann piping



aroCOLLECT is an accessory to transform flexoTHERM 400V into an air-to-water heat pump.

With this high-efficiency air-to-water heat exchanger, no heat loss occurs between outdoors and indoors. Fully modulating ventilators with minimal sound production allows the system to run very quietly. This three phase, intelligently driven air collector uses the ambient air temperature to warm the brine fluid just like the ground loop. Using the aroCOLLECT air source brine collector with flexoTHERM 400V will transform the ground source heat pump to work as an air source heat pump. With Green iQ this will be a highly efficient air source heat pump with good SCoP ratings.
