Low-noise operation of technical systems is of key importance in areas where people are always present such as apartments and offices, and the air conditioning units are generally installed very close to the user.
In order to meet the specific requirements for comfort without compromising on performance in all operating modes, MTA has developed the HCYGNUS tech reversible heat pumps that use the environmentally friendly refrigerant R410A. The already low noise level is further reduced by the use of electronic fan speed controllers, allowing the fans to spin more slowly when the need to cool is lower.
Seasonal efficiency values are highly important when it comes to climatic comfort - and very much so in heat pump mode. Thanks to the integrated storage tank and frost detection system (FDS) that detects the quantity of ice that builds up on the external coil and only activates defrosting cycles if necessary, energy consumption is drastically reduced.
Features
- Very low noise levels;
- High EER/COP values and high seasonal efficiency;
- Ideal for air conditioning applications in commercial or residential premises;
- Wide operating boundaries;
- Optimised defrosting cycles in heating mode thanks to the unique frost detection system (FDS)I (Min. ambient ...

- Data based on operating in cooling mode with water outlet temperature 7 °C
- Water inlet/outlet temperature 40/45 °C, relative humidity 87%, ambient temperature 7 °C;
- Data based on nominal conditions at full power, ambient temperature 7 °C, relative humidity 87%, condenser inlet/outlet 40/45 °C;
- Conforms with European Regulation 813/2013 for low temperature heat pumps (BT) on a scale of A+++ to D
- Data based on operating in heating mode and water outlet temperature of 45 °C;
- Measured data in cooling mode conforms to ISO 3744;
- The noise values are based on a system, incl. circulation pump, operating at full power under nominal conditions at a free field distance of 10 m, reflective surfaces, from the condenser side, at a height of 1.6 m from the ground.
The noise values, weights and dimensions given are for a basic system without any additional options.
