Conair Group Inc.'s new line of EarthSmart portable chillers are the first to use new environmentally friendly R410A refrigerants, according to the company.
Initially, Conair is launching air- and water-cooled EarthSmart chillers in six sizes, from 1.5 tons to 15 tons. The company plans to add larger and smaller sizes.
Soon, all chillers will need to use a new, non-ozone-depleting refrigerant like R410A, said Wes Sipe, general manager of the Conair Heat Transfer Group.
The U.S. government has mandated the phaseout of conventional R22 refrigerants, known as Freon, by 2010, Conair said.
Conair is stepping up to make the transition now, because it is the right thing to do environmentally and it is best for our customers in the long run, Sipe said.
Developing a portable chiller to use R410A gave Conair the opportunity to re-evaluate every component of the unit, and make the new chillers easier to use and maintain.
All models will have the same multifunction microprocessor control system, based on open-architecture software. These control features historically have been available only on high-end chillers, but now they are standard equipment on the Earth¬Smart.
In other news, improvements made to Conair's Medline puller/ cutter enable producers of small-diameter medical tubing to set, control and validate the gap between puller belts automatically.
Conair has replaced the conventional manual-adjustment wheel used to establish and maintain the gap between belts with a small servomotor, in-line planetary-gear reducer and digital controller.
Maintaining the gap between belts controls the consequent pressure, or crush on the tubing. The new control communicates with an in-line laser gauge, which sends a real-time signal of the outside diameter of the tube. The puller gap automatically follows the actual size of the tube.
Medical extruders can validate control over this process variable.
Conair is headquartered in Cranberry Township, Pa., a Pittsburgh suburb.
