Air Curtains & Dock Door Seals

Incentives for other upgrades

If you are a commercial provider, take advantage of incentives to reduce your costs and maximize energy efficiency.

Disclaimers
Incentives cannot exceed 50% of eligible project costs.
Air curtain:
Building eligibility: Existing and new buildings are eligible. The space adjacent to the door must be heated during the heating season by natural gas fueled equipment. For existing buildings, replacement of existing air curtains is not eligible. For new construction applications where the air curtains have been installed on pedestrian doors instead of a vestibule are not eligible. Eligible shipping/receiving doors include doors classified as dock-in (truck trailers dock at the doorway and doorway is typically four feet off the ground) or drive-in (door opens and closes to allow traffic to pass through doorway and doorway is typically located at ground level). Any applications where an air curtain is being installed on dock doors where other mechanisms that combat infiltration at the shipping/receiving door are present, such as dock door seals, are not eligible under the Drive-in category of shipping/receiving doors but may qualify for a custom incentive. Dock-in applications of shipping/ receiving doors are restricted to two specific scenarios: (1) installations where there is no air curtain or dock door seal or (2) upgrades that replace existing deteriorated dock door seal with air curtain. Shipping/receiving doors with vestibules are not eligible.
Equipment eligibility: Eligible equipment must be tested by a third-party performance standard (ANSI/AMCA 220-05) and installed as per manufacturer specifications. Heated air curtains are not eligible. Other door sizes not listed may be eligible- please contact an Enbridge Gas Energy Solutions Advisor.

Dock door seal:
Building eligibility: Existing buildings only where the space adjacent to the door is heated during the heating season by natural gas fueled equipment. New construction is not eligible for this offer. If other mechanisms that combat infiltration at the shipping/receiving door are present, such as air curtains, it is not eligible. Replacement of existing deteriorated seals or the addition of new seals to an existing building with shipping/ receiving dock doors that do not have any type of seal in place are eligible. Replacement of existing deteriorated seals are only eligible if the incentive application is approved by an Enbridge Gas Energy Solutions Advisor and if the existing seal has a minimum average two-inch gap based on a six-point measurement. This measurement must be taken and approved prior to purchase to be eligible. For deteriorated seals, submission of measurement form is mandatory.  For all industrial customers, replacement of existing deteriorated seal projects is only eligible if the incentive application is approved by an Enbridge Gas representative.
Equipment eligibility: Two types of seals (compression and shelter) are eligible based on door size. Compression seals (this is a foam pad that is wide and fixed to the door, with a minimum of 40 oz. vinyl cover) on 8' x 8', 8' x 9' and 8' x 10' doors. Shelter type seals (this is a curtain like seal with minimum 40 oz. vinyl with shelter frame that is made of steel with foam pad or foam core that compresses against the sides and top of the trailer box) on 9.5' x 10.5' or 10' x 10' doors. Other door sizes not listed may be eligible but must be reviewed and approved prior to application.

Average = [gap1+ gap2+ gap3+ gap4+ gap5+ gap6] / 6

Average = average deteriorated seal gap (inches)

• If average ≥ 2 in. = deteriorated seal, eligible
• If average < 2 in. = not deteriorated seal, not eligible

Please note that you are measuring “absence” of the seal (physical hole or gap) that was in place before but that is now torn.
