MTA Aries G chiller air-cooled

Air-cooled chiller Aries G

Air-cooled chillers with low GWP refrigerant R454B; hermetic scroll compressors. Cooling capacities from 161 to 867 kW

Increase comfort, protect the environment The Aries G chillers represent a purposeful development and construction aimed at reducing the operating costs of air-cooled chilled water production; without compromising on reliability and environmental protection.

For chilled water air conditioning systems in noise-sensitive environments, options with soundproof hoods for the compressors, soundproof housing for the compressors and EC fans are available.

For special cooling water requirements in production, configurations for low water outlet temperatures down to -10 °C, stainless steel shell and tube evaporators, internal water storage tanks and pumps can be ordered.
