2.6 SURE-SAVE Cooling Injection
(Optional: 125-750 scfm model)
Standard: Models with I-C Level 3 Controller
Dryers outfitted with the SURE-SAVE option automatically
protect the refrigeration compressor from damage due
to excessive inlet air temperatures. A temperature sensor
continually monitors the compressor operating
conditions. If the temperature exceeds standard design
conditions, the SURE-SAVE cooling injection valve
automatically redirects cooling energy back to the suction
side. This allows continued operation with an elevated
pressure dew point rather than initiate a high
temperature shutdown. To protect the dryer, high inlet
air temperature shutdown will occur if inlet air
temperature exceeds 140°F.
