Copeland Discus Digital™ with CoreSense TechnologyCustomer Testimonials
“Reliable refrigeration equipment is important to maintaining our perishable product. The Discus Digital™ has reduced compressor cycling in our store by 56%. It extends our compressor and contactor life expectancy in addition to reducing inrush current to lower energy costs.”
Ken Flavin – Manager Refrigeration & MaintenanceSobeys, Inc, Stellarton, NS, Canada
“The Rack was operating with 900 compressor cycles per day. We were days away from Grand Opening, and tried a variety of controlling methods to reduce cycle counts and still maintain product temperatures without success. We retrofitted the Digital unloader on only one compressor and the impact was amazing. Within minutes of activation, compressor cycles were reduced to 12 starts in four days for the entire Rack. ”
Michael Ellinger - Regional Facilities ManagerWhole Foods Market, Inc, Rocky Mountain Region
“Whole Foods Market is recognized for the freshest in perishable products. The Discus Digital™ reduced the suction pressure range by 89% within minutes of activation. Case temperature fluctuations have also tightened supporting our commitment to freshness for our customers.”
Michael Ellinger - Regional Facilities ManagerWhole Foods Market, Inc, Rocky Mountain Region
Copeland Discus Digital™ with CoreSense Technology Benefits Precise Control Of Suction Pressure And Temperature
– Longer Shelf Life & Less Food Shrink Because Of Minimal Food Temperature Fluctuations– More Consistent TXV Operation
Reduced Cycling Of Compressors– Extends Contactor Life– Extends Compressor Life
Reduced Defrost Cycle Time– Tighter Temperature Control Minimizes Formation Of Frost On Evaporator
System Efficiency Improvement– Eliminates Over/Under Shooting Of Suction Pressure Set Point– Allows Increasing Suction Pressure Set Point– Reduces Inrush Current / Power Usage
Paradigm Shift In Parallel System Design– No Need For Uneven Paralleling For Compressor Staging– Using Common Compressor Selections Simplifies Replacement Needs
