The Mark CALFLO is a Make-up Air System for heating. This means that the burner (and the flame) is located directly in the air flow to deliver maximum performance. The flue gases are so clean that they may be blown into the building. The CALFLO is suitable for rooms requiring large degrees of ventilation. This apliance is equipped with a modulating stainless steel burner and a seawater-resistant aluminium housing.
Possible applications include sand blasting areas, welding areas, and the processing industry.
