Mydax Air Cooled Refrigerated Process Cooling Chiller Systems for heat transfer fluid temperature control


Air-cooled Liquid chillers are required for industrial temperature control applications when no source of water is available for cooling the refrigeration system condenser. These units use fans to dissipate the heat removed by the refrigeration system.

Mydax liquid chiller systems utilize our patented proportional refrigeration control, rugged tubular steel frames and touchscreen controls along with leak free pumps, process fluid flowmeters, stainless steel brazed plate heat exchangers and all brazed copper piping. Each system undergoes rigorous quality assurance testing with system documentation and performance graphs provided.

Mydax designs can also include multi channel, independently temperature controlled cooling / heating loop applications where 1, 2, 3 or more recirculating temperature control loops are needed from one liquid chiller system.

When cooling requirements begin to exceed 24,000 Btu/Hr (2 ton), the heat being dissipated into a room becomes a concern. At that point we generally suggest either a Water Cooled Chiller or an Outdoor Air Cooled Chiller.
