At Plastics USA, Thermal Care Inc. will display its new line of central chillers, the TC Series, which uses a new compressor with a magnetic bearing technology — so the shaft is suspended in the air.
Normally, the compressor shaft and bearings need oil for lubrication. But the magnetic technology has no friction, eliminating the need for oil, Thermal Care said. The shaft is the only major moving part.
Thermal Care is showing the TC centrifugal compressor at Plastics USA, Sept. 28-30.
Thermal Care President Don Gruenberg said the energy-efficient, whisper-quiet compressor has been used for several years in the commercial air-conditioning industry for offices and other large buildings. But the TC marks its first application in industrial cooling, he said.
A built-in variable-speed motor drive and the frictionless bearings, which require only two amps to levitate the shaft and start it rotating, help save energy by eliminating inefficient cycling of the compressor, Thermal Care said.
TC central chillers use R-134a refrigerant. The TC provides 79 points of diagnostic control per compressor.
It runs quietly, at just 71 decibals, so the chiller needs no special sound-deadening.
Thermal Care placed its first TC chiller in a factory in California, where it has been running for several months. The energy savings, compared to an existing screw compressor chiller currently in the plant, will total $26,320 for the first year.
Thermal Care would not name the customer, but said the company qualified for a $30,000 energy-savings incentive by purchasing the TC.
