Q-ton is a heat pump system with CO2 natural refrigerant to be used for the production of domestic hot water, in residential, commercial, industrial and tourism applications.

Q-ton is able to produce hot water to 90° C in presence of -25° C outside temperature. No one before had managed to do so much! To obtain this result, the new two-stage compressor is employed, produced and patented by Mitsubishi Heavy Industries.

CO2 Q-ton heat pump system has a thermal power of 30 kW – which it succeeds in keeping constant also with an outside temperature of -7°, thus allowing effectively the quantity of hot water supplied throughout the period of the year. Q-ton can produce about 750 litres of hot water, post mixed at 45° C, for every hour of operation. It can also be installed in modular combination up to 16 units, thus permitting to reach a production capacity of 480 kW (12,000 litres of hot water per hour).

CO2 heat pump system can be easily installed, meeting the needs of the small building, as well as of the large spa, with an easy and intuitive touch panel control system.
Q-ton realizes an energy saving higher than any other combustion system able to ensure the same use temperature of 90° C. It can be combined with conventional combustion systems with no particular plant-engineering problems, being placed outside the thermal station.
Moreover, CO2 Q-ton heat pump system is the ideal system in building industry, able to fulfill the prescriptions required by the new Legislative Decree g.s. n. 28 of 3 March 2011. In fact, this Decree imposes a production of 50% of hot water by renewable energy, in order to obtain the construction permits on new buildings.
