What is Q-ton?
Q-ton is an air-to-water heat pump which utilises patented compressor technology and CO2 gas as a refrigerant to offer a reliable and efficient hot water solution for a range of commercial applications. The Q-ton utilises the world’s first two-stage compressor (combining rotary and scroll technology) to maintain high efficiency and significantly high performance, even with cold outside air temperatures.
In addition to offering a sanitary grade hot water solution, the Q-ton can now also be used in variety of space heating applications with return temperatures below 30°C. The new system deign also includes combination mode which allows the unit to deliver hot water supply as well as spacing heating.

50 | 1. Performance of operation to top up during intermediate season shows the capacity measured under the conditions that outdoor temp is 16°C DB/12°C WB, water inlet temp is 17°C and how water outlet temp is 65°C. | |||
51 | 2. Performance of operation to top up in cold region shows the capacity measured under the conditions that outdoor air temperature is -7°C DB/-8°C WB, water inlet temperature is 5°C and hot water outlet temperature is 90°C excluding heater for anti-freezing water (191W). | |||
52 | 3. Operating sound shows a value is measured at 1m in front of the unit and 1m above the floor in an echoic room where the sound is slightly resonated. Accordingly, if the unit is installed on an actual site, it is normal that the measured sound levels may be higher than the value shown above, due to surrounding noise and echo within the room. | |||
53 | 4. Pipe size 20A=DN20=20mm=3/4in. | |||
54 | 5. The actual hot water outlet temp may vary ±3°C from target temp according to the change of outdoor air temp and water inlet temp. If feed water inlet temp is 30°C of high and outdoor air temp is 25°C or higher the water temp may be controlled to ensure temp does not increase too much. | |||
55 | 6. Ensure clean water is used. Water quality should follow the standard which MTH specifies. If the water quality if not up to standard it may cause issues within the unit such as scale build-up and/or corrosion. | |||
56 | 7. These articles mentioned above may vary without notice accordingly to development status. | |||
57 | 8. Electrical installation work must be performed by an electrical installation service provider qualified by a power provider of the country. Electrical installation work must be executed according to the technical standards and other regulations applicable to the electrical installations in the country. | |||
