Description
The Ruffneck 25kW 480V T3B FX6 Electric Air Heater (FX6-480360-250-T) is a specialized explosion-proof forced air heater built for hazardous industrial environments. It’s certified for a wide range of explosive gas and dust classifications, making it ideal for high-risk locations. Designed for extreme climates, it operates efficiently down to −58°F (−50°C) with safety features such as dual over-temperature protection, over-pressure safeguards, and a secondary thermal protection contactor. Built with durability in mind, it includes a heavy-duty core, epoxy-coated steel cabinet, and zinc-plated fasteners. It also features three long-life heating elements and an aluminum fan for efficient heat delivery. Installation and maintenance are simplified with a large junction box and a removable heating core.
