If it's got electrical power (e.g. self contained with pumps) try EN60335-2-40. Otherwise, if it's under 0.5bar gauge there's no requirement and if it's more than 0.5bar gauge at any point the Pressure Equipment Directive may apply.

Drop me a line direct if you need more help.

I've looked through the OJ (.pdf, april'00) for both the LVD and the EMCD and
I can't come up with anything obviously applicable to demonstrating
compliance for a water-to-water heat exchanger. Process water is
(re)circulated through the exchanger and where heat is traded to a reservior
of cooling water. Enclosure is all metal. Any advice?

Many thanks
