The big end of the EarthSmart range just got bigger

Thirty tons bigger, to be exact. That's the chilling power you can now expect from the largest unit in the portable chiller line from Conair (Cranberry Twp., PA).

Thirty tons bigger, to be exact. That's the chilling power you can now expect from the largest unit in the portable chiller line from Conair (Cranberry Twp., PA).

EarthSmart chillers were the first in the plastics industry to use environmentally friendly R-134A and R-410A refrigerants, and the lineup has now been expanded to include larger models and dual-pump units. Three new sizes (20, 25, and 30 tons cooling capacity) have been added in air- and water-cooled models so that the range now extends from 0.5-30 tons. The new larger models and dual-pump chillers also feature simpler, more powerful standard controls and construction features that result in a more durable and more compact package, according to Conair. 

Conair EarthSmart 30 tonsThe popular dual-pump design incorporates a divided reservoir and two pumps so that the process-cooling circuit is separated from the internal circuit that recirculates the process water fluid through the chiller evaporator. Conair recommends using a chiller with dual pumps to ensure consistently higher flow to the mold in applications where process flow requirements can fluctuate. The additional pumping capability, along with separation of process and recirculation functions, allows the chiller to perform well even as process cooling demands change.

For higher-capacity, central-cooling applications, Conair also has modified the design of air-cooled models as large as 500 tons, making use of R-410A and, in the largest sizes, another compliant refrigerant designated R-134A. Water-cooled central chillers, available as large as 1000 tons, use R-410A in the smaller sizes, R-134A in midsized chillers, and R-123 refrigerants in the largest units.—[email protected]
