Altecnic ERES Expansion Vessel, 18 Litre Part No: ER-18LTVESS

  • The vessel is fabricated by welding the various sections together, resulting in a very reliable structure suitable for internal pressures up to 5 or 6 bar.
  • Non-replaceable diaphragm held securely in place by a flange.
  • Water is never in contact with the steel vessel.
  • The Eres diaphragm has been specially developed for heating applications. Suitable for temperatures up to 100°C, resistant to ethylene or propylene glycol mixtures, and low gas permeability.
  • Suitable for Grant boilers.

How it Works:

In a closed heating system, 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 diaphragm against the tank towards the inlet.

As the temperature increases, the expanded water volume pushes against the diaphragm creating additional volume for the water to enter. When the temperature decreases, the pre-charge pressure forces the water from the tank and back into the main heating system. This maintains a constant pressure within the heating system helping to reduce energy consumption.

In the event that the diaphragm within the expansion vessel could be subjected to temperatures above 100°C, the vessel must be protected by an additional vessel.
