Self-contained, propane-cooled floor cases use Danfoss SLV controller and variable speed compressor.
Danfoss, a leading manufacturer of high-efficiency electronic and mechanical components and controls for air-conditioning, heating, refrigeration and motion systems, and provider of energy management and control solutions for the food retail industry, was chosen by Supervalu, Inc., to provide a range of energy-saving products and support for a remodel project that has resulted in the development of the company’s first grocery store operating 100% on natural refrigerants. Specifically, Danfoss played a key role in supporting Supervalu, one of the largest companies in the U.S. grocery channel, through refrigeration system design and strategy to installation and commissioning.
The remodel of Supervalu’s Albertsons store in Carpinteria, CA included a facility expansion – doubling the store’s footprint to 43,000 square feet, and the conversion of an R22-based refrigeration system to one that uses nothing but environmentally-friendly natural refrigerants. The new system operates primarily on carbon dioxide (CO2), but also includes ammonia in medium-temperature cascade systems and propane in select self-contained floor cases.
The Danfoss products used throughout the store include CO2 controls for low-temperature applications, compressor controls, temperature transducers, pump and liquid vapor separator safety controls. The self-contained, propane-cooled floor cases also feature the Danfoss SLV controller and variable speed compressor. In addition to helping the store save energy, money and resources by simplifying system control, Danfoss verified proper system communication between these state-of-the-art case controllers and the Danfoss control system to ensure proper monitoring.
“We're proud to have been a part of this exciting project,” Billy August, account manager at Danfoss Electronic Services, says. “We applaud Supervalu for its sustainability initiatives and for taking the step forward to installing and operating a refrigeration system that uses only environmentally-friendly natural refrigerants. Danfoss has been a part of more than 2,000 installations of CO2-based systems throughout the world, and we know that this conversion will not only benefit Supervalu's business, but also its customers and community.”
Prior to the store’s grand re-opening ceremony on July 25, 2012, Supervalu recognized Danfoss’ Electronic Services team for its role and contribution to ensuring the store’s refrigeration system would operate efficiently and sustainably.
