Fridge Smoker Conversion. - Page 2

post #21 of 32


I agree. with mneeley490, I even found small blocks of polystyrene  (packing foam) in the walls within the polyurethane insulation that was in contact with the interior walls of the cooler. definitely a toxic fire hazard. If I tried using it without changing the insulation it would've melted for sure. Scrapped that particular smoker build for the fridge pictured above, was too much work.

 

Its a cooler and not designed for heat retention and fire resistance, very highly likely the insulation needs to be replaced. Have yet to see one that didn't have to be. Unless its rock wool or fiberglass insulation. But then that usually a heating cabinet anyways.

Even won some serious cook-offs as well. Thanks for the tip on the insulation deal. That's a lot of work!! Wont be doing that. The pics below are from  pellet smoker. 



 





 





 





 



 


Tony, One of the main things on the forum is SAFETY, food and personal safety, are of utmost concern to us here. You have two knowledgeable people telling you that the insulation in your cooler will not safely handle the heat you intend to use in it. If you have no regard for your own personal safety or the safety of those around you, then buy all means avoid a little extra work, and put everyone in danger!!

Thanks for all the input fellas. By any chance, anyone know what the max possible temp is attainable with that foam insulation prior to being toxic? Just a curiosity thing. If that's the case that I cannot use it as a 160-250 degree smoker without redoing the insulation it will very well be a cold smoker.

doesnt take much for it to start melting usually, Best to keep it as a cold smoker. Toxic fumes will start far lower than melting or ignition points.

After a few verbal tongue lashings from y'all, I decided to open this up to see how hard it was to get the foam out. Luckily, Hobart builds it where the skin comes off


Most of it broke off in huge chunks. The stainless insert looks like it will simply slide out if I can free it up. The insert is already sliding around inside the frame. I'm intending to remove all that foam crap and use the Rolux.

Glad it wasn't a major pain in your arse! You will be glad you put the extra effort into your build cause now your pit will be capable of doing it all and I will not be reading headlines in your local paper about you keeling over from toxic fume inhalation!
Keep Smokin!!!

You lucked out, my friend! Mine wouldn't open from the outside, and the foam was like hard glue.

Ok, so is this the insulation to use? MSDS says fire resistant, no flash point, no fumes. Can withstand temperatures up to 1177 °C (2150 °F). Saw it at home depot. 60sqft for $45.

Heres an update. Got all the foam out. Gonna torch the rest as it was the easiest method versus scraping or using a pressure washer. One note, I needed to brace the chassis. The foam and insert is what held it all together.
