What is the Q-ton?
The high efficiency Q-ton is an air-to-water heat pump using CO2 gas as a refrigerant, which can be used in a variety of applications for the supply of sanitary hot water. Q-ton has been featured as the world’s ﬁrst two-stage compressor (combining rotary and scroll technology). It maintains high efficiency and signiﬁcantly improves performance at cold outside air temperatures.
MHI’s design team launched this innovative unique air source heat pump to allow maximum efficiency, with minimal carbon footprint all controlled from a comprehensive touch screen panel. Currently with the increasing pressure of the use of low GWP (Global Warming Potential) refrigerant, we believe CO2 heat pump is the way forward to comply with future regulations as well as market trends.
Why the Q-ton?
Q-ton delivers outstanding performance and environmental beneﬁts to a varied number of applications. Q-ton is exceptionally energy efficient which results in big reductions in both power and carbon emissions.
Q-ton uses safe and highly efficient CO2 as a refrigerant which is environmentally friendly as it is a natural gas and does not contain harmful cological impacts compared to other products using standard refrigerants.
Furthermore the Q-ton uses a constant hot water supply from 60°C to 90°C and maintains the full capacity at a very low ambient temperature. Therefore there is no requirement for external heating source and as a result this saves valuable installation time and costs
- High efficiency
The industry’s highest coeﬃcient of performance (4.3 in intermediate season). Massive reductions in both running costs and CO2 emissions.
- Long-term reliability
High quality robust technology. High quality robust technology.
- High performance
60°C to 90°C water supply even with outside temperatures as low as -25°C. The ability to maintain 100% capacity down to -7°C
- Environmentally responsible
GWP (Global Warming Potential) = 1. ODP (Ozone Depletion Potential) = 0.
- Easy operation
Advanced, but simple to operate touch screen panel with LCD. User-friendly schedule setting and one-touch ﬁ ll up operation.
