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
