Modine’s HEX electric unit heaters are designed for hazardous industrial locations
where potential for explosion exists due to the presence of flammable gases, vapors,
powdered-metals or dusts. HEX electric unit heaters are UL-listed for Class I, Divisions
1 & 2, Groups C & D; Class II, Division 1, Groups E, F and G and Class II, Division 2,
Groups F and G. UL temperature code shall be T3B 329°F (165°C) for Class I and II,
indicating maximum operating-surface temperatures.
Standard features include:
• Liquid to air, finned tube heat exchanger core.
• Ethylene glycol water mixture used as heat-transfer fluid in the heater core, providing
-49°F (-45°C) freeze damage protection.
• Thermally protected, automatic reset, explosion-proof, motor driven fan moves
air across finned tubes for even heat distribution.
• Automatically reset, bimetal high-limit provides over temperature protection and is rated
for 100,000 cycles of service.
• Pressure relief valve provides over-pressure protection.
• Epoxy coated, 14 gauge steel cabinet contains heater core, motor, and fan assembly.
• Narrow-gap, two-piece fan-guard shields all moving parts.
• Adjustable extruded aluminum louvers allow directional control of air.
• Copper conductor wires enclosed in steel conduits carry all electrical power.
• Rated for 100,000 Cycles of Service • UL Listed • Sealed Heat-Exchanger Core • Ethylene Glycol for Heat
Transfer Fluid • Protected, Explosion-Proof Electric Motor • Two-Piece Fan-Guard
