New technologies are constantly arriving in the refrigeration sector. From time to time, we’ll take a look at some of those advancements. This article will focus on developments in motors and ice machines.


A division of Epec Engineered Technologies, EC Fans & Drives, gave a report on its EC electric motors specifically for HVACR. They factor in the introduction of new energy-efficiency standards derived from the U.S. Department of Energy (DOE).

Simon Gidney, president of EC Fans & Drives, said, “Anyone involved within the supermarket industry should be aware that profit margins are tight, typically between 1 percent and 3 percent. With the ECplus™ motor you can expect up to 80 percent savings in energy consumption. The opportunity to save even one-eighth of a cent would prove to be a drastic improvement in the refrigeration and HVAC industries.”

He noted that refrigeration accounts for over 35 percent of the energy consumed in a standard supermarket, and that due to stringent legislation targeting energy savings, commercial refrigerators and freezers have become focused on. “This has resulted in supermarket procurement departments specifying that all new and retrofitted commercial refrigerators and freezers are fitted with electronically commutated motors. Coca-Cola and other leading OEMs in the commercial refrigeration sector have already begun implementing the cost-saving benefits of the ECplus motors and their energy-efficient technology.”
