Fermenter from pressure tank?

[Taquina]

Does anyone know if I can make a fermenter from a pressure tank like this one?

I just had one replaced at my house, and wonder if I can remove the membrane from the old one and modify it to a fermenter.

Thoughts? Advice?

Thanks!

Perhaps if you replaced the membrane with one that's food-grade. I don't think fermenting in the bare metal would be a good idea, as these bladder tanks aren't usually made of stainless steel, IIRC.

Looking at the Varem web site, the only pressure/expansion tanks that are stainless steel are unpainted stainless. The rest of them - and particularly the red painted models - are carbon steel tanks - which is not going to work well for anything to do with beer in direct contact...

Cheers!

Damn! Thanks for the research and responses! I saw it and thought it had fermenter written all over it. Wasn't sure it was stainless steel though. Will keep looking...
