Discus with CoreSense Diagnostics Case Studies
Supermarket In Columbus, Ohio Saves $4,500 With Discus with CoreSense Diagnostics
Discus with CoreSense Diagnostics Locked Out Compressor Due To High Discharge Temp. Investigation
Of High Discharge Temp Lead To Discovery Of High To Low Leak In Valve Plate. Copeland Discus with
CoreSense DiagnosticsPrevented Compressor Failure Resulting In Technician Replacing Valve Plate
Instead Of Replacing Entire Compressor. Store Saves Approximately $4,500.
Discus with CoreSense Diagnostics Technology Prevents
Delay Of Store Opening Of Supermarket Location In North
Carolina
During System Installation, Contractor Started Compressors With
Liquid Lines Incorrectly Piped Into Suction Header. When
Compressors Started, Large Amounts Of Liquid Filled Suction Header
And Compressors.Discus with CoreSense Diagnostics Detected The
High Discharge Temperature And Pressure, And Instantaneously
Locked All Compressors Off, Preventing Damage To The
Compressor, Avoiding Delay Of Store Opening.
The Fault Detection And Protection Of Discus with CoreSense Diagnostics Saved
Supermarket In Stone Mountain, GA, Approximately $6,000
One Leg Of Contactor Failed Sending Only 2 Phases Of Power To Compressor. Discus with
CoreSense Diagnostics Immediately Shut-Off Compressor & Displayed “Single Phase Fault”.
Technician Reset Compressor To Restore. Contactor Completely Failed Sending No Power To
Compressor. Discus with CoreSense Diagnostics Displayed “No 3-Phase Power” Which Prevented
Compressor Failure Resulting In Technician Replacing Failed Contactor Instead Of Replacing Entire
Compressor. Store Saves Approximately $6,000.
