Hi, I want to understand this IC81W Motor air to water heat exchanger. Ref : QLKD-150-063-3-2-4-23-7-2-X . Please explain to me the details like pipes inlet and outlet Ds and materials etc...
which standard is applied for coding ?

Why not contact manufacturer?

The problem with sloppy work is that the supply FAR EXCEEDS the demand

We searched but the Manufacturer ( ABB Coiltech) is closed very long time ago. there is no documents for it either. Please chech the photo.

I'd hazard a guess 0.063 wall tubes, but really it is all a mystery. If you would disassemble and measure everything you might make sense of the nameplate.

Thank you. I wonder which specifications the manufacturers normally applied for or adhered to for manufacturing coolers ?. maybe I will find the interpretation of the nameplate there !

Well, unless you find a Code nameplate (or similar) you may never know. It may be such as to be exempted from normal PV codes (apparent 17 liter volume, for example), in which case it may only be designed to internal or customer standards.

I am guessing (from the single design conditions) that this is an air cooler.

I'd further guess the type designation to include (no particular order, not all inclusive):

Basic configuration, no. tubes, tube gauge, length, perhaps design pressure & temp, no. tube passes, perhaps some info on fins, perhaps codes for materials of construction. Mind you, this is all guesswork on my part.

Mike
