Ruffneck FX6-208360-075-TD Explosion Proof Electric Forced Air Heater w/Thermostat and Disconnect Switch
Ruffneck™ FX6 heaters are cULus-certified for use in hazardous locations. They are designed for the harshest environments such as dry indoor industrial applications, oil refineries, petrochemical plants, pulp and paper mills, grain elevators, hazardous waste storage facilities, wastewater treatment plants, etc., where specific explosive gases or dust may be present. Suitable for extreme environments with low ambient operating temperatures as low as -58°F (-50°C).
The FX6 offers a larger junction box for easier installation, additional limit controls, and a heavy-duty core. Two levels of pressure and thermal protection provided standard on all units for best-in-class safety and reliability. The heater core assembly is contained in a sturdy, epoxy-coated 12-gauge steel cabinet, which also carries the motor and fan assembly. Adjustable louvers allow directional control of the airflow. A narrow gap, two-piece fan guard is provided to shield all moving parts. All fasteners are zinc plated for corrosion protection.
Ruffneck™ heaters are built to last. All Ruffneck™ products are subjected to exhaustive technical analysis and testing during design and development and are manufactured under a registered quality assurance program. As a result, they have consistently proven their safety and reliability.
