Carrier has launched the AquaSnap 61AQ, a high-temperature air-source heat pump using propane (R290) refrigerant, marking its entry into the market for commercial applications. The product is designed and optimized for R290, delivering heating up to 75°C at outdoor temperatures as low as -7°C. The monobloc version ranges from 40kW to 140kW, while the modular version allows connection of up to four units, extending the capacity range to 560kW. The heat pump features inverter scroll compressors and EC variable-speed fans, offering efficient performance based on demand and a SCOP of around 4 at 30oC/35oC. Noise levels are reduced to 78dB(A). The propane charge is limited to a maximum of 5kg per circuit for safety reasons.
The company introduces its latest innovation: a propane heat pump unit.
