Reflex Potable 0.5 Litre Expansion Vessel/Shock Arrestor

Altecnic offer a complete range of mini expansion vessels for use with potable water in domestic hot and cold water systems. The expansion vessels are manufactured to meet the requirements of PED 97/23/EC Directive and BS EN 13831:2007 ‘Closed expansion vessels with built in bladder for installation in water’.

Manufactured in Noryl plastic or stainless steel Pre-pressurised air chamber with synthetic rubber compound bladder. The internal surface of the vessels in contact with the water are resistant to corrosion, thus maintaining water quality External surfaces are black or a natural finish for stainless steel. Suitable for temperatures up to 90˚C, resistant to ethylene or propylene glycol mixtures and has low gas permeability. Altecnic mini expansion vessels are all tested according to the Pressure Systems Directive.

In a closed hot water circuit, the water cannot be compressed so any increase in volume, created by an increase in temperature, has to be accommodated by an expansion vessel. When water is cold, the pre-charge pressure forces the bladder to collapse until the pump is started when the bladder starts to inflate. As the temperature in the system increases, with the associated increase in pressure and volume, the expanded water enters the bladder creating additional volume and lowering the pressure. When the temperature decreases, the pre-charge pressure forces the water from the bladder and back into the main water circuit.

Altecnic recommend that the air pressure is checked annually and adjusted if necessary. This can be done using an air pressure gauge and foot pump.
