We are always on the lookout for interesting Forum Evening topics.  Please do let us know if you have something you want to tell us about in heat transfer.  This might include, information on new heat exchangers or new uses of existing exchangers, R&D developments, new software or standards, or, indeed, anything that will interest our Members.  Email us with your ideas.  Forthcoming forums are listed on the Events page.
