Cranberry Township, Pa.-based Conair Group has a new line of chillers that it's billing as Green Cool technology as well as a new radio-frequency identification (RFID) system that it says simplifies and error-proofs resin distribution.
The auxiliary equipment producer says the chillers in the new Eco-brand line can operate in conditions from -20° to 125° F, which allows them to be installed outdoors to provide chilled water indoors for plastics processing machines.
Conair serves a variety of markets, including packaging, medical, transportation and construction, with more than 450 products.
The Eco line has six models of chillers with cooling capacities from 40 to 120 tons. All the models feature direct-drive hermetically sealed scroll compressors, which Conair officials say are reliable, low maintenance and efficient.
Dual refrigeration circuits and multiple compressors provide built-in redundancy for the smaller units, while the larger ones (80-120 tons) also incorporate independent process fluid circuits.
The Eco chillers have a modular design so the units can be connected to a single control interface, providing centralized control of up to 12 temperature-control circuits. For example, a series of 60-ton units could deliver up to 720 tons of cooling.
The Eco chillers are heat-transfer products with several energy-saving features, according to Jim Fisher, general manager of heat transfer.
"Among other energy-saving features, the new central chiller line offers instantaneous, continuous calculations performed to deliver increased efficiency under partial load, with automatic refrigeration pressure control," Fisher said in a news release. "Variable-speed fan motors and dynamically controlled valves also ensure efficient operation at low noise levels and deliver increased temperature stability under varying load and condenser inlet temperatures. We call this Green Cool technology."
The Eco chillers come with Conair's "uptime guarantee," the release also says.
