The FX5-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 FX5-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™ FX5-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 FX5-SD the safest and most robust explosion-proof unit heater available. FX5-SD heaters are CULUS approved for use in hazardous locations.
Suitable for the following Hazardous Location Classifications:Class I, Division 1 & 2, Groups C & D
Class II, Division 1, Groups E, F & G
Class II, Division 2, Groups F & G
