Motivair MHR chillers offer cooling & simultaneous heating capacities from 60–450 nominal tons at standard rated conditions. These chillers are available in air-cooled, water-cooled and split systems configurations and come standard with two refrigeration screw compressors built in two independent refrigeration circuits. The Heat Recovery System can be selected for either series or parallel configuration. This flexibility allows design engineers to reclaim 20–100% of the heat in the cooling systems. Using a Motivair MHR chiller with heat recovery can double the efficiency of a standard chiller, making it ideal for LEED certified buildings and owners looking to maximize chiller performance.
