Introducing Enershield Air Barriers
Get an overview of the one-of-a-kind articulating nozzle and other unique features incorporated into Enershield Air Barriers/air curtains that are best suited for industrial, retail and commercial applications. Air barriers are a great way to essentially keep your doors open and closed at the same time.
| Highly applicable for cold storage, pharmaceutical and food facilities that need to adhere to strict government safety regulations. |
✓ Enhance comfort for your workers and customers: Keep excessively warm/cold air out of your facility by sealing off up to 90% of outside air.
✓ Save on energy costs: Enershield Air Barriers save 15-20 units of energy for every 1 unit consumed.
✓ Increase worker productivity: Reduce lost work hours due to illness from prolonged exposure to drafts.
✓ Extend the life of your HVAC system: Heating and cooling equipment does not need to cycle as many times with an air barrier.
✓ Adhere to safety regulations: Keep out contaminants (extreme weather, dust, insects, truck exhaust fumes, etc.) and remain compliant with strict food and safety regulations.
✓ Improve worker safety: Prevent moisture build-up on the floor from condensation.
Information
ASHRAE Standard 90.1-2019: Air Barriers Can Substitute Vestibules
Doorway air curtains were approved […] as alternatives to vestibules on most commercial building entries in […] ASHRAE Standard 90.1-2019 “Energy Standard for Buildings Except Low Rise Residential Buildings.” […] The approval is good news for retail, restaurants, healthcare, hotels, office and other facility owners, because they can now opt to forego the expense of vestibules in new construction, or repurpose significant square footage for more productive uses by retrofitting existing vestibules.Source: Connex. “Air Curtains Allowed as Vestibule Substitutes in Upcoming ASHRAE Standard 90.1-2019.” 31 July 2019. <https://www.connexfm.com/News/Industry-News/View/ArticleId/24115/Air-Curtains-Allowed-as-Vestibule-Substitutes-in-Upcoming-ASHRAE-Standard-90-1-2019>
Return on Investment: Within Two Years (Average)
Enershield Air Barriers operate efficiently and outperform any other air curtain or air door on the market by a wide margin. With these energy-efficient air barriers, you’ll dramatically enhance your indoor comfort while saving money. Enershield Air Barriers have proven to provide a return on investment within an average of two years and have a total lifespan of up to 20 years on direct drive and belt drive models.
Creating a Strong Environmental Separation
The thermal imagery below shows how Enershield air curtains create a strong environmental separation.
The Only Way to Keep Your Door Open and Closed at the Same Time
With the cost of energy continuing to rise, heating and cooling costs are becoming more costly than ever. If you are a business that keeps your doors open multiple times a day to load/unload materials or have a high amount of foot traffic, your energy costs are even greater.
Enershield air curtains are custom-made for each doorway to ensure a seal up to 90%. These air barriers also maintain air speeds of 800 fpm above the ground, which creates an ideal environmental separation between outside and inside air temperatures, saving you money on heating and cooling costs.
Air barriers create a strong environmental separation to:
- Enhance indoor comfort and safety for workers and customers.
- Keep out inclement weather (extreme heat/cold, rain, snow and humidity).
- Prevent contaminants from entering the facility, such as bugs, dust, pests and exhaust fumes.
- Reduce stress on HVAC systems, increasing their longevity.
Air Barriers Prevent Frost Build-Up in Cold Storage Applications
Vertically-installed air barriers are recommended for coolers and freezers to prevent ice and frost build-up caused by air leakage and air exchange between two different environments.
Recirculatory Air Door With a Built-in Air Barrier
AirSeal creates an invisible barrier utilizing high-velocity laminar airflow to maintain dual climates, keeping your cold side cold and your warm side warm. This horizontal recirculatory air door is a “smart door” that automatically adjusts to your temperature and humidity changes while maximizing energy efficiency with superior optimization control.
