Altecnic Eres 35L Heating Vessel C/W Feet

Altecnic expansion vessels are manufactured to meet the requirements of Pressure Equipment Directive 2014/68/EU, and BS EN 13831:2007 ‘Closed expansion vessels with built in diaphragm for installation in water’.

Design
The vessels are fabricated by welding the various sections together which results in a very reliable structure suitable for internal pressures up to 6 bar.
Epoxy coated and available in red.
Non-replaceable diaphragm held securely in place by a flange.
Suitable for temperatures up to 100˚C, resistant to ethylene or propylene glycol mixtures and has low gas permeability.
In the event that the diaphragm within the expansion vessel could be subjected to continuous temperatures above 100˚C, the vessel must be protected by an additional vessel (VDI 6002 directive).
