Spiral baffles

[vesselguy]

Hi,
I wish I kept the sale literature when I had it but I didn't. Can anyone remind me which company sells the spiral baffles for shell and tube exchangers?
Thanks.

Thanks Christine. That's what it was.

Here is another type that works in the tube. We have used this approach on several exchangers to improve/increase tube side heat transfer with good results.

Unclesyd,
Thanks but the improvements I need are for the shell side as I am cooling 9 to 12 API emulsion there.

Just a quick shot as to whether you were after overall or just the shell side.

Koch also had a Heli-Cal design baffles.
There are some coditions stated that will make the design effective.

Thank you again. I didn't know Koch made them. I thought ABB patented those helical baffles. I am asking a local fabricator to quote me a design with the ABB helixchanger. But with this additional knowledge, I'd find another fabricator that can build the Koch exchangers and get a comparison. Thanks Unclesyd.

Have you considered Plate & Shell technology? Much more efficient than tubular with or without spiral baffles - approx 25 - 30% of the size. Fully welded plate pack within a shell
