Maintinaing constant temperature

[vtmike]

Hi,

I need to heat a space of 6' x 4' x 2' to a temperature of 200 degrees farhenite and keep the temp constant (plus minus 20 degree F) for a period of 12 hours.

My approach is to use a heating coil & fan heating system, but am having trouble finding a source which provides design guidelines for such a system. Another option is to buy an off the shelf industrial heater.
Having trouble with questions like how big should the boles in the container be to ventilate the system (while keeping temp constant)?

Does anyone know of good resources to design or buy a coil & fan heating system?

Thanks,
Mike

Why do you need to ventilate?

If this is a dryer, you need to account for losses from the box and the ventilation air to 200degF and discharging it, rather than just heating a sealed box.

The ventilation air flowrate will need to be calc'd to remove the moisture, which will dry off in proportion to the RH.
