A second generation of energy-saving centrifugal chillers (also called frictionless or oil-free chillers) has been announced by Thermal Care, Inc., Niles, Ill. In 2004, Thermal Care was the first to introduce this new type of central chiller based on the unique Danfoss Turbocor compressor. In addition to their quiet operation and compact footprint, energy savings of up to 35% with these air- and water-cooled chillers were said to justify their higher initial cost. Now, refinements to both the compressor and Thermal Care’s controls are said to improve their efficiency even further. According to Thermal Care, savings with air-cooled models under some conditions have been up to 70%. TC Series chillers (60 to 180 tons) now boast a wider operating range and greater unloading capability. They reportedly can operate at any loading level, vs. a previously recommended lower limit of around 33%. Also, air-cooled models that before could have startup difficulties at outdoor temperatures below 0°F, now are said to function well at -20 F. (847) 966-2260 • www.thermalcare.com
