Applications, he said, include being mounted as part of a condensing unit on top of display cases in various sections of the store. In this way, long refrigerant lines can be reduced. "This is distributed scroll technology," Muir said.

He said scroll alarms are based on oil level rather than oil pressure, as are recips. He told an audience that included many people who install and service supermarket compressors, "This increased sensitivity must be accounted for on the start-up of scrolls."

He also noted the company's increasing involvement with screw compressors. Contour models now encompass 16 medium- and low-temperature displacements (20 to 90 hp). All are geared to supermarket refrigeration.

Primesource Wholesalers

Mark Gibson, vice president of wholesaler sales and marketing, told the audience that the manufacturer is committed to placing at least two of what he called PrimeSource wholesalers in virtually all sectors of the United States.

He described PrimeSource wholesalers as those who have a full line of Copeland products, parts, and support services. He said there are now more than 800 PrimeSource locations "with advanced logistics technology and the speed and convenience of online ordering."

He also noted that the company has a developed what it called a Passport CD with training modules for wholesalers, use of which can lead to Copeland certification. "Each of the 800 PrimeSource wholesalers must be certified," he said.

Additional developments included an updated website (www.copeland-corp.com) with a section specifically for supermarket customers.
