COMPRESSED AIR AND VACUUM SYSTEM HEAT RECOVERY
COMPRESSED AIR AND VACUUM SYSTEM HEAT RECOVERY Requirements: • Heat recovery system must include automatic controls to switch from winter to summer operation. Systems with only manual damper controls are not eligible. • Heat recovery systems installed for backup or redundant air compressors or vacuum pumps do not qualify. • The project must result in an estimated net reduction of BTUs consumed in the facility to be eligible. • This incentive is for the installation of a new heat recovery system where one did not exist previously. Replacing an existing heat recovery system or upgrading an existing heat recovery system from manual to automatic controls does not qualify. • The static pressure in the area where the compressor or vacuum pump is enclosed must remain the same. • If outside air is used in the system, antifreeze protection must be considered. EQUIPMENT UPGRADES AND RETROFITS Measure Description Code Incentive Unit Compressed Air Heat Recovery PS2257 $60 HP Vacuum Pump Heat Recovery PS3928 $60 HP Incentive is limited to 50% of the project cost, including equipment and external labor (internal labor eligible for schools and government customers). General Requirements: Applies to heat recovery for the offset of space heating provided by natural gas-fired heating equipment only. Systems that offset the use of propane, oil, electricity, etc., do not qualify. Heat recovery systems that offset natural gas-fired process heating equipment may qualify for a custom incentive.

PRO TIP As much as 80%-93% of a compressor’s electrical energy is converted into heat. Installing heat recovery can then put 50%- 90% of that generated heat to good use. Installing automatic damper controls ensures that recovered heat is used to its fullest potential even during transition months when some days require heating and some require cooling. It also ensures that energy savings are not dependent on staff maintaining manual controls.
CUSTOM PROJECT IDEA Talk to your Energy Advisor about custom incentives that may be available for compressed air system optimization that may involve installing new compressors, automation/ sequencing controls, dryers, or additional storage to improve the efficiency of the compressed air system.
