Low noise operation of technical systems is essential for continuously occupied premises such ashomes, offices and light-commercial buildings, where air conditioning units are usually placed inclose proximity to the users. In order to satisfy the specific comfort requirements of these type ofpremises, without compromising performance in all operating conditions, MTA recommends theHCygnus Tech series of reversible heat pumps with environmentally friendly refrigerant R410A. Thealready very low noise levels have been further reduced by installing electronic fan speed controls,which run at lower speeds as cooling or heating demands decrease. Seasonal efficiency levels areeven more evident in heat pump operation, with clear benefits in terms of climatic comfort, thanksto the integral storage tank and Frost Deteting System (FDS), designed to detect the quantity of iceaccumulating on the external coil, so that defrost cycles are performed only when appropriate,thereby minimising the power consumption
Nominal cooling capacity 5–53 kW
Nominal heating capacity 7–65 kW
