DUAL MOTOR COLD STORAGE AIR CURTAIN

The Dual Motor Cold Storage Air Curtain is designed for cold rooms, refrigerated warehouses, workshops, factory entrances, and other industrial door applications.

Equipped with two high-performance copper motors, the air curtain delivers strong and stable airflow to help reduce cold air loss when doors are opened. It creates an effective air barrier between indoor and outdoor environments, helping improve temperature stability and reduce unnecessary energy loss.

The unit is suitable for door heights of approximately 2.5–3.5 meters and is available with spray-painted metal housing, 201 stainless steel, or 304 stainless steel housing for different installation environments.
