Engineered for high-level horizontal installation, the BAR4\/GFAC delivers a powerful heated air stream downward across the doorway. This prevents cold air ingress while breaking up cold air pooling at floor level — a critical factor in high-traffic loading bays and logistics facilities. With a maximum nominal output of 54.0kW and gas input (net CV) of 58.9kW on high fire, the unit\u003c\/p\u003e\u003cp\u003eprovides substantial heating capacity to support wide openings up to 2,250mm. The high velocity air stream (15.3 m\/s average outlet velocity) combined with four centrifugal fans ensures balanced airflow across the full module width. The system operates on a 220-240V~50Hz single-phase supply and incorporates three-speed airflow control, allowing adjustment to suit mounting height and site conditions.
