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. For hazardous location heating, rely on the Ruffneck™ FX6 heater for the most dependable, trouble-free service available. The FX6-SD is the next generation Ruffneck™ explosion-proof electric air heater, built for severe duty applications that can lead to accelerated wear of electrical components and damage to the heater core. The FX6-SD is specifically designed for severe duty applications including locations with: ? Fluctuating power quality ? Temporary power generation ? High vibration ? Dirty or corrosive atmospheres or ? Extended maintenance intervals Only the Ruffneck™ FX6-SD incorporates a dedicated shunt trip circuit breaker which operates independent of the control circuit. It is triggered by a redundant heater core high temperature limit enabling primary interruption of line power to safely protect the heater core. Additional standard features include a definite purpose high capacity contactor, explosion-proof Arctic Duty motor and heavy gauge wiring to make the FX6-SD the safest and most robust explosion-proof unit heater available. FX6-SD heaters are CULUS approved for use in hazardous locations.
