CO2 heat pump for high temperature domestic hot water production.
Q-ton is a heat pump with natural R744 (CO2) refrigerant to be used for high temperature domestic hot water production in residential, commercial, tourist and industrial applications. Q-ton can heat and produce hot water up to 90°C in the presence of an outdoor temperature of -25°C. The new dual stage compressor manufactured and patented by Mitsubishi Heavy Industries is used to achieve this result.
The use of R744 refrigerant gas (CO2) guarantees a very low environmental impact. It in fact has a global warming index(GWP) of 1, and a potential for ozone layer destruction (ODP) of 0.
