I am working on a custom project that involves extensive fiberglass work. Of course the weather has dropped well below the optimal working conditions for Isophthalic Polyester Resins. There is ‘no’ awaiting spring to return to complete this project, it is already behind schedule as it is. I am needing to heat the workable space and the project itself with some form of heating that is ok to use in a combustible vapor environment. I know that already limits many of the well known heat sources out there.
I plan on heating the project itself along select regions of the project with directed infrared bulbs. I also need the ambient environment to be heated as well. I am looking for some of the larger oil filled radiant heaters available but can only seem to locate residential models, as always. I am familiar with an alternative industrial type, no-flame, oil filled heaters that use diesel fuel that are used a lot out in the midwest and northern climes. This would work perfectly as I could pipe the heat in via canvas duct from a slightly remote location. I thought some of the equipment rental places in the NC Raliegh triad area might have them, of course they do not.
Anyone have any ideas how I could heat up this area without any open flame, or electric strip sources.
I have considered purchasing a barrel heater kit with legs, etc; and make a 50 gallon horizontal drum heater. I could pump the heat off of the barrel alone, into the area with canvas duct and a ventilation fan. The positive pressure within the duct would prevent any vapors from meandering up the duct back towards a hotter heat source. It does not need to be hot in the area, just warmer than 50 degrees.
I can work the Isophthalic polyester resin down to 60 degrees without any structural issues.
