For Sale 12 vdc powered heat exchangers

[LAMBCRUSHER]

I have 4-6 of these 4x4 heat exchangers with 57.9 CFM 12 vdc 3 watt puck fans. They would make great spot heaters or even ps oil coolers. Some have bent fins. Brass and aluminum. Let's say $40.00 each, 2 for $75 + postage.

Inlet outlet OD measurement

 

[LAMBCRUSHER]

suppose that would help...stay tuned...

 

[LAMBCRUSHER]

ID = 3/8"
OD = 7/16"+
bulge begins at 3/8" and is about 9/16" at its poles

Or hook one up to an on-demand propane water heater and pump and maybe add a thermostat to make a tent or vehicle heater...

 

[LAMBCRUSHER]

yep, possibilities are endless. hook up a water chiller and run spot coolers in your shop...time for these things to find their projects!

 

[woytovich]

Is there any provision for mounting these? What are the dimensions of the main part (that would leave the in/outlet sticking out? How slow is the slow speed? (I guess a pot/rheostat could be added instead?)

I should have thomas edisoned these mawfs so their worth may soon increase...I'll post up some more on them later...


sorry I'm unprepared...

 

[woytovich]

[LAMBCRUSHER]

of course, of course...I joke coarsely on occasion. I'll get some more on these tonight or tomorrow.
