Stainless steel vs Titanium on H.E. Plates
Stainless steel vs Titanium on H.E. Plates
(OP)
Hi,
We are going to buy a replacement kit for our heat exchangers. On the other side, we are having troubles with biofilms and sediments clogging in the HE, so we need to dismount them almost every month to clean up the plates. In the HE runs non-treated water, taken directly from a little dam, cooling the refrigeration water of an electric generator, which is clean water.
Obviously the main problem is the water quality, yet, we need to buy a replacement kit of the plates.
¿Could we buy the plates in stainless steel instead of titanium?. We haven't had any corrosion problems in the piping system, so, ¿is titanium really necessary?.
Does the titanium prevent the biofilms growth?
I'll appreciate your help.
Regards,
Juan

Have you considered treating the water? There are systems that use an electrical current and Cu electrodes to put a small amount of Cu into the water. These are often used on board ships. It might be a good alternative to using a chemical treatment.

It is a simple system and reliable.

We're going to make a water-quality analisis to determine the chloride ions and pH. According to the supplier, those values determine if we can use stainless steel instead of titanium (resistance to corrosion). Yet, i don't know if the material change (except by the roughness) could change the biofilm rate of growth. ¿Any idea?.
