Twisted tubes heat exchangers

[KALEM09]

I would appreciate your suggestions in finding suppliers of twisted tubes. I know that Brown Fintubes/Koch has the patent to produce them, but I've heard that there are are suppliers too, therefore they are no longer protected.

The only supplier with engineering and design experience is Brown.
In non-US markets there may be people copying the look, but they will have little knowledge of the engineering.

They are still listed and sold under the Koch banner.

I have nothing against buying from Brown, but they are not willing to supply the tubes only and since I am bidding for a repair work I look for other sources, possible other licensed producers. Thanks for suggesting Heseman. I will contact them. What about suppliers in Europe ?
