COMPRESSED AIR
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.
