Condensate Pan Termination 1

[dmi]

I have a project to raise 4 chilled water cooling coils that are currently floor supported (concrete floor) with no condensate drain pans. There is a lot of good information about how to design the cross section of the pans. However I have not been able to see how to terminate the ends of the pan. How do you work around the structural supports and maintain a viable pan? Space is very limited.

A picture is a thousand words. Are these cased coils and the pans you are talking about are auxiliary drain pans?

If so support the pan from the underside, sit the coils on something inside of the pan.

Lol or make them into cased coils and support the casings

Use stainless steel pan. TIG weld stainless steel flashing around structural support, to the pan.

Thank you AbbyNormal and lilliput1. The coil has the mfg's frame around the coil. The plan is to use the bolt holes in that frame and some angles beneath to support the coils. My plan is to have the end supports welded together and then galvanized prior to installation. At the point where the coil frame, the new supports and the drain pan intersect the current cross section for my drain pan will be:
bottom will slope slightly to the downsteam side of the coil;
the the top will be 3" tall before the coil, notch down to 1" deep under the coil, and then return to the 3" deep profile down steam. Does any one see a problem with that profile?

Again picture is 1000 words

My cased coil comment was basically to enclose the coil and drain pan assembly in a casing and then support the casing.

Your 'manufacturer's frame' almost sounds like the tube sheets and side plates of a coil.

Tube sheets = where you see the return bends penetrating

Side plates, at the ends of the fins.

Take the "V" out of HVAC and you are left with a HAC(k) job.
