High Output Gas Fired Heated Door Curtain for Industrial Loading Bays

The Powrmatic BAR3/GFAC is a high-performance 40kW gas fired heated industrial door curtain engineered to provide active environmental control across large commercial and warehouse door openings.

Designed for high-level horizontal installation, the BAR3/GFAC delivers a powerful heated air stream downward across the doorway. This simultaneously prevents cold air ingress and breaks up cold air pooling at floor level, a common issue in high-traffic loading bays and logistics facilities. With a maximum nominal output of 36.5kW and input (net CV) of 40.0kW, the unit provides substantial heating performance while maintaining controlled airflow via centrifugal fan technology. The average outlet velocity of 15.3 m/s ensures consistent environmental separation even in exposed doorways.

The three-speed fan configuration allows airflow adjustment to suit mounting height and operational conditions, with high speed airflow reaching 8,100 m³/h.
