Pid Digital Control Fan

Post by Northwoods Traveler » January 11th, 2015, 5:31 pm

Been using a process controller setup and furnace fan to run multiple styles of charcoal/wood smokers and use another one to control an electric smoking cabinet. Can take the heat down super low to smoke cheese or fish or crank it up to 400 to bake a pizza with charcoal.

Anyone else have any luck with homebuilt digital systems?

I've been tempted to build one but I've heard it doesn't work for an RF offset. Welcome to the crew

Northwoods Traveler,

I have my controller ready to plug in but ordered a case to pack it all into. It's wired and SEEMS like it should work but I have not have the time to cut the aluminum box to fit the cutouts. I only have a small Dremel tool to cut the parts out. My blower is a plastic junk fan and I'm not pleased with it. I may need to find a metal one that would improve the isolation from heat without being to far removed from the heat. I'm using the TA 4


Make no mistake, there ain't no powder in this Puff ! And... I'm not really a crazy person but I play one in real life

What size fans (in cubic feet per minute) are people using on their home built PID temperature controllers? I am looking at some that range from 16 cfm to 52 cfm. I have a patio size smoker, 24"x36". I cut the air intake way back to maintain 225-250. Seems like a smaller fan would be easier on the controller when maintaining a set temperature, but I don't know. I'm thinking of using a 25CFM fan. The 52cfm fan costs only $1 more. What size fans do the store bought temp controller's use?

The squirrel cage on Northwood's looks pretty big. Do I need to rethink my fan size?

I'm not sure what size the pit bull is but I would get the biggest you can so it won't work as hard. :kewl:

Too big will cause overshoots that 16 cfm should be good


No matter how many times i cut, its still to short!! :-w

I have the Pit bull with the cyber q controller. It can move a lot of air but the controller doesn't allow it to come on full power if the temp is near the goal temp it just puffs a little air in as needed.
