ACCESSORIES, ANCILLARY EQUIPMENT, AND CONTROLS
CYCLING OR VFD-CONTROLLED REFRIGERATED AIR DRYERS Requirements: • New dryers must be properly sized to meet the needs of the compressed air system. • New dryers must be cycling or variable frequency drive (VFD)-controlled refrigerated dryers replacing non-cycling refrigerated dryers. The replacement of desiccant, deliquescent, heat-of-compression, membrane, or other types of dryers are not eligible. Installation of controls to existing dryers does not qualify for a rebate. • If air dryer is integral to another piece of equipment (i.e., is part of the air compressor), provide a manufacturer’s specification sheet for that piece of equipment to confirm that it includes a cycling or VFD controlled air dryer. • For new construction, cycling or VFD-controlled refrigerated dryers must be installed instead of non-cycling refrigerated dryers. • Use CFM value of dryer when calculating rebate amount. Application Measure Description Code Rebate Unit Retrofit Cycling or VFD-Controlled Refrigerated Air Dryer PS2264 $2 CFM New Construction Cycling or VFD-Controlled Refrigerated Air Dryer N-PS2264 $2 CFM DEWPOINT DEMAND CONTROLS FOR DESICCANT DRYERS Requirements: • Dryer must have a dew point sensor at discharge to monitor demand. • Dryer controls must control the regeneration process based on actual dewpoint instead of regenerating based on time alone.
• Dryer controls are not eligible for backup/redundant desiccant dryers. • Use the CFM value of the dryer when calculating the rebate amount. Application Measure Description

EFFICIENT DESICCANT DRYERS Requirements: • Must replace a heatless desiccant dryer that uses compressed air to regenerate the desiccant. • Backup and redundant desiccant dryers are not eligible. • Use the CFM value of the dryer rating when calculating the rebate amount. • Efficient desiccant dryers which also have dewpoint controls may apply for this rebate and for PS4363, provided the dryer being replaced did not have dewpoint controls or this is a new installation and there was not an existing dryer.
