Product Details
Ruffneck™ FX6 heaters are CULUS-certified for use in hazardous locations, specifically designed for the harshest environments including dry indoor industrial applications, oil refineries, petrochemical plants, pulp and paper mills, grain elevators, hazardous waste storage facilities, and wastewater treatment plants, where specific explosive gases or dust may be present. These heaters operate effectively in extreme environments with low ambient temperatures as low as -58°F (-50°C). The FX6 features a larger junction box for easier installation, additional limit controls, and a heavy-duty core. It includes two levels of pressure and thermal protection as standard for enhanced safety and reliability. The heater core assembly is housed in a robust, epoxy-coated 12-gauge steel cabinet, which also holds the motor and fan assembly. Adjustable louvers facilitate directional control of the airflow, and a narrow gap, two-piece fan guard protects all moving parts. All fasteners are zinc plated to prevent corrosion. The heaters are built to provide dependable service and are subjected to rigorous technical analysis and testing during design and development, manufactured under a registered quality assurance program ensuring consistent safety and reliability. Key features include a hazardous location rating of Class I, divisions 1 and 2; Groups C and D; Class II, Groups E, F, and G; Class II division 2, Groups F & G; and Class I zones 1 & 2, Groups IIA & IIB with a temperature code of T3B [329°F (165°C)]. The enclosures meet NEMA type 7 & 9 standards and are intended for dry indoor use only, as they should not be immersed in water or stored in areas exposed to rain or snow. Backup overpressure protection is standard on all heaters, and the units are now equipped for low ambient operation.
