Tandem ChillersWater Cooled Chillers

If you have 70° F to 105° F building supply water (cooling tower water) to use for your condenser cooling, Tandem offers high efficiency water cooled chillers with compact size allowing for easy installation in hard to reach places where space is severely limited. With our oversized brazed plate evaporators and condensers we can offer some of the highest EERs available today. Whether it is a matter of cooling an entire office complex, a data center, a laboratory or a hi-rise apartment complex, we have the expertise and equipment to meet any job requirements.

All our water cooled chillers feature either high efficiency “SCROLL” compressors with dual refrigeration circuits or single “SCREW” compressor with single refrigeration circuit, stainless steel copper braze plate evaporators, stainless steel copper braze plate condensers, our exclusive intelligent chiller control system, and a NEMA 1control panel with optional NEMA EEMAR Type 4/12.
