Mitsubishi Electric EW-HT-G05 and EW-HT-C-G05: the high-temperature, low-GWP units for low- and medium-temperature heat elevation or recovery

Mitsubishi Electric expands its range of water-source heat pumps and chillers for high-temperature hot water production with low-GWP refrigerant R513A and heating capacities from 73 to 130 kW. The new EW-HT-G05 and EW-HT-C-G05 ranges, with environmentally friendly R513A gas, offer new installation opportunities and upgraded features.

EW-HT[-C]-G05 allows for the release of the gas heating network, ensuring sustainability through the divestment of fossil fuels while providing high reliability and simplification of the system. These families provide ultra-high temperature water and are the ideal solution for replacing heating systems with gas burners or electric heaters.

Designed to meet the needs of comfort, process and IT cooling applications, EW-HT[-C]-G05 units feature a wide operating range: condenser discharge water temperature up to 78 °C and evaporator discharge water temperature from 7 °C to 40 °C.

Both EW-HT[-C]-G05 ranges consist of 4 sizes with two scroll compressors on two refrigerant circuits to ensure maximum reliability.

EW-HT-C-G05 then, is the water-cooled high-temperature chiller designed for heat reuse applications in data centers. This new solution opens up great opportunities for heat recovery and reuse, especially in the IT Cooling segment. The operating limits of this type of unit, which are certainly higher than those of other common water-to-water chillers, offer new possibilities for both conventional air-cooled (~20 °C evaporator discharge) and state-of-the-art liquid-cooled (up to 40 °C evaporator discharge) systems. Due to the high temperature of water leaving the condenser, EW-HT-C-G05 can recover waste heat from data centers, generated by cooling technology equipment, and use it in a wide range of applications, thus achieving a higher energy reuse factor (ERF).
