thanks Matt

these units are 316 stainless, they are copper brazed (as most of them are) but copper content is minimal.

I have sent a few on for solar water applications which is great. The shop might reject the coupon code when you buy because of the filter bags, if it does just ignore the postage make a note and I will adjust the invoice.

Small update:
30 plate smooth are all gone
If you are a brewer I have a good special on 20 "wort" heat exchangers for wort cooling - very effective from the feedback I have received.

I am also setting up some "express packs" consisting of HE, 2 filter bags and brass fittings. These will all fit in a standard 3kg satchel and will of course have a discount applied + the "biofuelsforum" coupon will work as well. (Should be going in the next couple of days)

Happy to be contacted via email as well geoffwin at gmail.com
