SPray Booth Heaters

[Dennis Alwon]

Does anyone know how these units are suppose to be installed. Someone asked me and I have no idea. The unit is a double heater not a single unit like the one shown so it has two wires sticking out at each end. Is there not an enclosure for these things? He says that was all that was there.

I can't believe they install as shown in this image

I'd really like to see the nameplate on those units. The basic Section that applies is 501.135.

They do have an enclosure, it just isn't explosionproof.

I don't believe the units are used in the room where paint is actually applied. If so, it isn't likely the location is classified. Hard as it may be to believe, it is conceivable that the units are suitable for Division 2 under Section 501.135(B)(1). I can't say the same for the apparent wiring method.

Don I don't know if these are the units being used but as described to me they are close to what he has. He saw pics and said they were very similar. He wants to use an lb out of each side and then make the connection on the back side. I said that he could run individual conduit where the wires would be run separately because of heat- 300.3(B).

This is how they are advertised, Spray/Baking booth Infrared halogen Short-Wave Paint Curing Lamp Heating Heater

Personally, I wouldn't touch them in any classified location, Division 1 or 2. Assuming the advertisement is accurate, it would have a "T Code" worst than T1 (450C/842F maximum) which is unacceptable for any gas, vapor, or volatile solid. The "Explosion-proof Function Test" they allude to is laughable.

Sorry Bob-- I don't know why I typed Don...I recall doing that once before also -- getting old. And thanks for your help on this as I know you have the experience in this area that most of us lack.
