 Introduction
 Altecnic offer a complete range of 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 diaphragm for installation in water’.

 Design
 * The vessel is fabricated by welding the various sections together which results in a very reliable structure
   suitable for internal pressures of up to 8bar.
 *The internal membrane is replaceable and is suitable for use with potable water.
 * Epoxy coated in blue.
 * Suitable for temperatures up to 99°C, resistant to ethylene or propyleneglycol mixtures and
   has low gas permeability.
 * Altecnic expansion vessels are all tested according to the Pressure Systems Directive.

 How It Works
 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 membrane sack to collapse until the pump is started when the sack starts to inflate. As the temperature
 in the system increases, with the associated increase in pressure and volume, the expanded water enters the
 sack creating additional volume and lowering the pressure. When the temperature decreases, the pre-charge
 pressure forces the water from the sack and back into the main water circuit.
