Commercial R32 air-to-water monoblocs
7th March 2024
GERMANY: FläktGroup has launched the FGAH-AH series of R32 two-pipe air-to-water monobloc heat pumps for commercial and industrial applications.
Available in six models from 15kW to 41kW, the units offer SCOPs of up to 4.76 (187% seasonal space heating energy efficiency) for low-temperature applications and SCOPs of 3.48 (136% seasonal space heating energy efficiency) for medium temperatures.
A wide operating range is offered down to -20°C outside temperature with simultaneous flow temperature of up to 45°C or up to 60°C at outside temperatures above -5°C.
The control option of on-site auxiliary heating rods also enables bivalent-parallel or bivalent-alternative operation. In summer, the units can be switched to cooling mode with media temperatures between -8°C and +18°C.
The units are equipped as standard with EC fans, electronic expansion valves, as well as a hydrophilic coating of the cu/al heat exchanger to improve the condensate drainage in heating mode.
Optionally, built-in speed-controlled pumps, as well as a suitable expansion vessel are available to reduce installation times and wiring effort. The speed-controlled scroll compressors adapt the heating and cooling capacity to the current demand in a wide working range.
