The aroCOLLECT accessory is an air source brine collector module which acts as an alternative to ground source and is compatible with 400V flexoTHERM models. aroCOLLECT is a three-phase air collector that uses the air temperature outside to warm the brine fluid for the heating system. This high-efficiency air-to-water heat exchanger ensures there is no heat loss between the outside and indoors which also operates with an extremely low noise level of 39.8dB(A) (400V, 5kW) allowing the product to be approved by ‘Quiet Mark’.
aroCOLLECT features modulating ventilators and a twin unit connection using balanced Tichelmann piping, reverse return system and is ideal for outdoor use in agricultural, commercial and residential projects.
