    It seems a little fast compared to my oven in reality. My oven takes about 45 min to heat to 400, But then, that's with 100+ metal silhouettes inside too. The spreadsheet said 34 min so 10 min off aint that bad at all.

    The majority of the ovens we build here on the forum are electrical powered ovens. 8' X 4' X 4' is the practical maximum size for an electrical oven and is large enough to powdercoat most hobbyist or small business parts.

    One degree per second is achievable heat rise rates with our electic ovens and that is not too long of a heat rise rate for most people.

    What kind of gas powered products can you offer us? Electric ovens are nice because you can build them yourself and achieve professional results without having to worry about carbon monoxide venting.

    Tell us more.

    powder is plastic...plastic is flammable... plastic dust [powder] is extremely flammable....open flame or even a spark could ignite any arrant powder floating in the vicinity... granted.. you'd probably need a pretty high concentration in the atmosphere around you...but it IS possible

    Thumbs up Re: Temperature Time to Rise Calculator

    Thanks for the calculator. Do you have any updated formula on the calculate the time to rise calculator? I am not building an oven but need to know the same time for the space to rise when I have electrical gear in a room with known heat gain to the space. My walls are better insulated than the oven time calculator.

    I don't think you are going to find any such calculator and the creator of this spreadsheet hasn't posted anything in 3 years. There are so many factors in what you are asking for that it's virtually impossible imo to create a 'calculator' to accomplish this.

    If you know the heat gain or btu, just provide equivilant cooling capacity.
