Reflex expansion vessels for heating systems
Mibec offer a complete range of Reflex expansion vessels to meet the requirements of most heating or cooling systems. Expansion vessels for heating systems are manufactured to meet the requirements of PED 97/23/EC Directive and BS EN 13831:2007 ‘Closed expansion vessels with built in diaphragm for installation in water’.
Reflex expansion vessels for potable water
Mibec offer a complete range of Reflex expansion vessels to meet the requirements of most heating systems and for use with potable water. 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’.
Materials and Technical Specification
Nitrogen and why it matters in an expansion vessel
Nitrogen is a dry, inert gas used in the Reflex range of expansion vessels to improve your vessels’ life span.
The oxygen in compressed air permeates through the membrane, reducing the pre charge pressure. During normal function, oxygen oxidises the membrane in the vessel, causing under-inflation and deterioration of the rubber. Dry nitrogen by comparison maintains proper inflation pressure longer, will not corrode the inside of the vessel and extends valve and expansion vessel life.
Nitrogen also prevents other types of corrosion as well; oxygen and moisture will corrode both aluminium and steel fabrications and also react with rubber.
