ModulAIR is a water chiller that brings robust serviceability and ASHRAE 90.1-2010 efficiency into a single compact package. Air-cooled chiller sizes are available in 5, 10, 15, 20, 30, and 40 tons. Each chiller can be used as a stand-alone unit or combined for installations up to 550 tons.

Building on the same premise of serviceability from its water-cooled brother, the new air-cooled modules feature an interconnecting stainless-steel header system. All refrigeration components can be replaced and serviced while the header remains in place. Compressors are isolated in a weather-proof enclosure ensuring compressor and electrical longevity. Optional insulation can be added to this enclosure for sound critical applications.

The air-cooled ModulAIR has many of the same features of the water-cooled version. For more information on the water-cooled model, click here. Air-cooled models are available with integral free-cooling coils. These coils work by bypassing the cooling water from the evaporator to a secondary coil located in the air-stream. The compressors are shut off and the condenser fans now cool this secondary coil. A built-in diverting valve automatically performs the switch-over. For cold climates, the chiller is available with low ambient controls which include; electronic head-pressure control valves, refrigerant liquid receivers, and heat tracing.

These chillers are available with R134a refrigerant for standard comfort cooling situations. They are also available with R507A refrigerant which is optimized for food processing, manufacturing and other low temperature applications. ModulAIR is a compact water chiller manufactured by Advance Industrial Refrigeration (AIR).
