Water Cooled Chillers

Tandem Chillers Inc. designs and manufactures water cooled chillers that are easy to install, easy to repair and easy on your wallet. The water cooled modular chiller is compact in size allowing for easy installation in hard to reach places where space is severely limited.

High Condensing Heat Reclaim Chillers

We also offer high condensing temperature water cooled scroll/screw chillers available with freons 407C and 410A. From 100° F Entering Condensing Water to 125° F.

We offer ultra high condensing temperature water cooled scroll/screw chillers available with only freon 134A. From 130° F Entering Condensing Water to 150° F.

The most impressive thing about our water cooled chillers are their "modularity" which allows you to remove and repair them in a matter of hours without interrupting the rest of the system. The unique split electrical control panel means that you can operate one compressor while you fix the other one. This saves you the extra expense of purchasing extra chillers for stand-by. If you are looking for long term savings and reliability, high operating efficiencies, ease of operation and the best protection and preventive maintenance program on the market, this chiller is the answer.

Applications for Water Cooled Chillers

If you have 70° F to 105° F building supply water (cooling tower water) to use for your condenser cooling, we offer high efficiency water cooled chillers. 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.
