New chiller is quieter, more energy efficient.

A brand-new central chiller to be introduced at this month's Plastics USA show in Chicago is claimed by the supplier to be a trend-setting advance in quietness, energy efficiency, and low maintenance. Thermal Care, Inc., Niles, Ill., believes it is the first industrial chiller maker to use a new type of compressor made by Turbocor Inc., Dorval, Que. It is oil-free, so there are none of the costs associated with oil management. More important, it has a built-in variable-frequency/variable-speed drive and frictionless magnetic bearings that require only 2 amps to levitate and start rotation of the compressor shaft. This start-up load is said to be much lower than for a normal compressor, which reduces a user's demand charges. Overall, the new compressor reportedly can cut energy costs by up to 30%

In addition, it is "whisper quiet," says Thermal Care, with a sound level of 71 dbA, vs. over 80dbA for standard units of similar size. The Turbocor compressor appears on Thermal Care's new TC Series, which come in 60- and 90-ton models (120 and 180 tons with dual circuits). It has high-efficiency electronic expansion valves and a PLC control with 79 points of diagnostic data per compressor. It is said to be cost-competitive with standard units at 90-ton size and larger. A TC chiller reportedly can replace an existing unit and pay for itself in energy and maintenance savings within two years. Tel: [phone] * PT Direct: 581WT
