Reznor Air Curtains

Reznor air curtains provide an energy-efficient, high-performance solution for separating indoor and outdoor environments without restricting visibility or traffic flow. Designed for commercial, industrial, institutional, and agricultural applications, Reznor air curtains help maintain interior temperatures, improve air quality, and reduce energy loss at frequently used doorways and openings.

This collection features Reznor Models HAC (unheated) and HACE (electric heated) air curtains, engineered to create a powerful, uniform barrier of moving air across doorways, loading docks, coolers, and freezers. When professionally installed, Reznor air curtains can achieve up to 90% effectiveness at blocking outside air, dust, insects, fumes, and moisture—helping conditioned air stay inside and unconditioned air stay out.

Reznor air curtains utilize an industry-leading pressurized plenum design that evenly distributes airflow across the entire opening, eliminating “dead spots” common with non-plenum designs. Backward-inclined blowers, heavy-duty direct-drive motors, corrosion-resistant painted steel cabinets, and flexible mounting options ensure long-term durability and reliable performance in high-traffic environments.

Available with advanced SmartTouch™ controllers, Models HAC and HACE allow precise control of fan speed, heat modes, on/off scheduling, and run cycles. SmartTouch controllers also support building management system (BMS) integration and service reminders for simplified operation and maintenance.

Reznor air curtains are ideal for vestibule exceptions approved by ASHRAE/IES 90.1 and the International Energy Conservation Code (IECC), offering a cost-effective alternative to traditional vestibules. They are also widely used for cold storage applications, helping reduce condensation, ice buildup, fogging, and safety hazards around freezer and cooler doors.

From retail storefronts and grocery entrances to warehouses, hospitals, manufacturing facilities, and cold storage areas, Reznor air curtains deliver improved comfort, enhanced safety, and measurable energy savings—often paying for themselves in less than two years.
