Hazardous location radiant heaters?

Dave Yates (PAH)

Feed bagging site needing heat. Lots of fine air-borne dust.

Oil & gas not available, but electric is available. Must be explosion proof! looking for hazardous environment rated radiant panels.

Pads or HX

Seems you could go with elect mesh pads under floor or wall or if more btu is needed an elect boiler with heat xchanger and std. pex or a fan coil(s) with warm air outlet.

Explosion Proof Heaters

There are a bunch of companies that make XP heaters for chemical storage buildings, etc. This is just one of them:

The dusty enviroment might pose more of a problem to the fans or fins though.

You could always go with a HW or steam system with the equipment located outside of the hazardous area.

XP

There are quite a few xp unit heaters available. Trane, Q-mark, etc..

Not familiar with xp radiant panels, though.. Good luck with that.

BillW@honeywell

Steam or HW system with pneumatic controls...

Just put any ep/pe switches in a non-hazardous area, or in appropriate XP enclosure.

Former salesman

I used to sell Brasch electric heat, and even THEY don't recommend their explosion proof unit heaters. Convert the electricity to hot water via a boiler located somewhere else and heat with radiant floor, wall mount radiators or an air handler with a spark-proof fan and a hot water coil located out of the explosion hazard area and filtered well.

Good luck!

tough conditions to be met

These are railroad cars with wheels removed. Welded together with adjoining sides removed for open floor plan. Steel floor suspended in air. Steel walls & a steel roof too - brrrrrrrrrrrrrrrrr.

No oil or gas available, or wanted for that matter.

The floor is a no-go rock solid heat sink! Ain't exactly in great shape either!

Toyed with the idea of electric water heater & hydropanels, but you'd have to see the fork-truck damage to walls to really appreciate how limited we'll be in locating panels. I haven't ruled that out completely yet, but Btu needs will be high. Side doors on the rail cars open for extended hours to receive and load product. Spring a leak with glycol-laden water & you've got an ample opportunity to poison tons of grain.

Radiant heaters

I am looking for an electric radiant heater for use in a recycle center. It must be suitable for use in a Class 1, Division 2 environment.

the advice above still applies

Hot water creates no ignition risk, so the simplest answer is still to locate the heat source outside the classified area and pipe the water to where heat is needed.

Catalitic heaters

There are several sour gas, propane and natural gas catalitic infrared heaters available for explosion proof locations. They are extensively used in the petroleum industry! Since yo do not have natural gas, you can use propane.
