Has anyone have altenative ways of increasing heat transfer from heat exchanger tubes. I have had success with spiral turbulators but am looking for alternatives. If anone has a contact or information on prebent finned tubing it would be greatly appreciated. loking in the 1-2 inch diameter stainless steel(409).

I've used such pre-bent fins in a wax/hydrogen mix electric pre-heater made by Armstrong-Chemtec to our entire satisfaction. The bending enabled avoiding stratification.
