Emerson Offers R-410A Copeland Scroll Digital Compressors

Emerson Climate Technologies, announced that its R-410A Copeland Scroll Digital is now available in a compete line of 3 to 12 horsepower models for commercial air conditioning applications. These units are designed to modulate compressor capacity from 10 to 100%. Copeland Scroll Digital is an important part of Emerson Climate Technologies' continuing commitment to providing contractors a broad line of advanced R-410A compressors.

Nordyne: iQ Drive® Technology Air Conditioner

Nordyne sources say the iQ Drive® technology from Maytag delivers high efficiency, 23-SEER cooling in a split-system air conditioner. Conventional air conditioners cycle on and off at full capacity to maintain the indoor temperature, unlike iQ Drive which is an inverter-driven rotary compressor that provides fully variable operation. It reacts to the cooling demand and changes the system capacity by modulating the speed of the compressor motors.
