Paint Cabinet Controlled Temperature

8 posts in this topic

For a long time I have struggled to get my E-Tex and paint just the right temperature ,due to my basement is to cold around 68 degrees I had an electrical control metal cabinet in my shop that was just right for my project, box dim.3feet x 2 feet x 6 inches deep. You can make this box out of just about any material including some kind of fiber board. I insulated the entire box with one inch insulation from Home Depot. The box can be any size.

Make sure that you put a divider in the box so you can install a very small 110 volt fan to circulate the air when the stat calls for heat by using a light bulb any were from 40 watts to 100 watts. Note the fan only comes on when the bulb comes on, no need to run constant. I set the temperature control to come on at 74 degrees and off at 75, works great, no more warming up anything

I have made a simple wiring diagram, make sure is fused 5 amps plenty sufficient to run the fan and light bulb

The A419 Johnson control you can purchase at any heating and cooling suppliers, the 4 inch fan 110 volts got it at Scientific Lab supplier the rest at Home Depot

Good solution and lots of good information.

 

I have built similar projects for curing plaster molds, but it is surprising how many other little jobs the box gets used for.

Aren't tek screws wonderful?  LOL.  

 

Nice cabinet setup.  

 

I used old electrical cabinets for different things all the time,  Having been a communications contractor for 21 years I have salvaged a few of them.

This is really cool. Would this run an electrical space heater, like 1000 watt? does it have a max amp load rating? does it have a mechanical relay? If the answer is in the pics I missed it.

1000 watts its way to much heater, would burn the cabinet down all you need is a light bulb to heat up the cabinet. 40 watts to 100 watts 110 volts bulbs it's all you need. Do not need a mechanical relay due to the load is very small less than one amp, the bulb load is handled by the A419 stat

yeah I don't want to put it in a cabinet, I was curious if this would run a heater.

The A419 stat can run a heater, but you do need a relay rated for 1000 watts, or a relay with a magnetic contactor
