PID controllers

I have a ? about the design. THe heat and water and fan is in the top and the fan blows to the door. How does it heat all the way to the bottom. Are the temps consistant from top to bottom?

I have this 30+ yr. old Leahy Incubator I'm restoring 21w x 46d x 54h and the heater element is on the bottome, fan and wafer thermostats are on top...FYI It worked for them years ago with great success.

There is a space between the top shelf and the door ... the air is pushed down.

Brinsea us several fans to try to acheive laminar flow in the Ova.

You could try this with a few PC fans dotted around. Experiment with placement.

It is good to have the air blowing across the water surface, by the way

Thanks for the reply Twigg. It's alot like a variable frequency drive for an a/c motor. You can get it to perform many, many functions but once you play with it awhile you can see how simple it actually is. (i like simple

)

I would think that for any "tall" style of incubator that if you used 4 small PC fans...2 of them mounted at the top front of the cabinet blowing downward, and then 2 mounted in the bottom back of the cabinet blowing upward..that would circulate the air from top to bottom really well and give you stable temps.
