Product Description

Cuztomized Export Model is the model for export ONLY,In order to protect our area oversea dealers ,no sales to inside China ,only direct export .

Description:

An expansion vessel, pre-charged with nitrogen instead of compressed air, to meet the requirements of most heating systems and for use with potable water. The Expansion vessels for potable water 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'.

Why use Nitrogen Instead of Compressed Air?

The oxygen in compressed air permeates through the membrane, reducing the pre charge pressure. During
normal function, oxygen oxidizes 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. Industry research indicates that oxidative aging is one of
the primary causes of decreased vessel life. Oxidative aging that is caused by the diffusion of oxygen from the
pressurized air cavity of the vessel to the outside atmosphere.

Tests have shown that if vessels are inflated with nitrogen, there is a significant reduction in failure.

How does Nitrogen help?

While both nitrogen and oxygen can permeate rubber,nitrogen does it much more slowly. It might take 6 months
to lose 2psi with nitrogen, compared to just a month with air. And nitrogen is far less reactive. It doesn't cause rust
or corrosion on steel or aluminum, and it doesn't degrade the rubber seal used in the pre charge valve extending valve core life and help prevent core leaks.
