New “eco2” chillers provide the dual advantages of ecology and economy, the company says. The line of air-cooled screw chillers has been optimized for use with HFC-407C, an environ-mentally responsible refrigerant, resulting in the highest energy-efficiency ratings for this category of chillers, says the manufacturer. Designed for mid-range commercial, industrial, and institutional comfort-cooling applications, the chillers are available in capacities from 80 to 200 tons.
