Central Chiller Systems.This manufacturer of process cooling equipment has developed TC Series central chillers using advanced compressor compressor, machine that decreases the volume of air or other gas by the application of pressure. Compressor types range from the simple hand pump and the piston-equipped compressor used to inflate tires to machines that use a rotating, bladed element to achieve technology. This centrifugal compressor Centrifugal compressors, (sometimes referred to as radial compressors) are a special class of radial-flow work-absorbing turbomachinery that includes pumps, fans, blowers and compressors. is said to offer many significant benefits over standard compressor technology. Benefits are said to include an oil-free design that eliminates the need for an oil management system and any related costs: only one major moving part, the compressor shaft, for increased reliability; whisper-quiet sound levels of 71 dBA so that no special sound deadening or mechanical room modifications are needed: and a built-in variable speed drive motor and frictionless, magnetic bearings (that require only two amps to levitate lev·i·tate intr. & tr.v. lev·i·tat·ed, lev·i·tat·ing, lev·i·tates To rise or cause to rise into the air and float in apparent defiance of gravity. and start rotation of the compressor shaft) that are said to eliminate inefficient compressor cycling. In addition, TC Series central chillers use R134a refrigerant re·frig·er·ant adj. 1. Cooling or freezing; refrigerating. 2. Reducing fever. n. 1.

The company placed its first TC Series unit (140 ton) in the field in a plant in California, where it is said to have been successfully running for the past six months.

The purchase of the TC Series chiller also qualified the plant for a $30,000 energy incentive. Based on the above example, customers replacing an existing central chiller can see a payback in two to three years. Thermal Care Circle 14 on card [ILLUSTRATION OMITTED] |
