Heating & cooling capacity between 120–200 kW Alternative heating solutions with electric, water coil, and condensing natural gas burners Electronic expansion valve (EXV) Rotary heat recovery option (condensation & sorption) Advanced Carrier control algorithm on air and refrigerant side Free cooling with enthalpic economizer Advanced Carrier patented defrost control High pressure and VAV ventilator and aspirator fan solutions High efficiency in Eurovent-certified full and partial loads

More energy efficiency at partial load for 99% of the work time. Only the necessary compressors are operated. Compressors operating under these conditions are more efficient in terms of energy consumption as they use all condenser and evaporator capacity. An electronic expansion valve at the cooling circuit allows for more secure and efficient refrigerant control. Crankcase heaters that are standard for all devices.

New generation Flying Bird IV fans that are made of (Carrier-patented) composite material and are more silent do not generate disturbing low-frequency sounds. The fan automatically switches to low speed at partial load and low outside temperature, two speed fan motor allows fan adjustment for the best efficiency. Defrosting is optimized with an automatic adaptation algorithm. This feature and the new coil design reduce the time for defrosting cycle by an average of 50%. For more security, an electric heater prevents ice accumulation at condenser coil base. All pipes and refrigerant parts are welded. Pressure sensors are mounted directly on the pipes. Dual inlet indoor fans have forward curved blades.
