Description

The Sealey IR37 is a powerful infrared space heater designed for heating large commercial and industrial areas using either kerosene or diesel fuel. This versatile multi-fuel heater delivers an impressive 40kW (136,000Btu/hr) output, making it capable of effectively warming spaces between 320-420m² in well-ventilated environments. Built for extended use, the IR37 features a generous 38-litre fuel tank that provides approximately 10 hours of continuous operation per filling, delivering excellent economy for contractors and site managers. The clean-burning infrared design makes it suitable for workshops, warehouses, construction sites, and agricultural buildings where adequate ventilation is present. Safety and practicality are prioritised throughout the design.
