Reflex 8 Litre Flow Through Potable Expansion Vessel

Reflex 8 Litre Flow Through Vertical Potable Expansion Vessel  

Altecnic offers a complete range of flow through expansion vessels to prevent the build up of potentially harmful bacteria in potable water by reducing stagnation within the vessel. The innovative design encourages flushing the vessel.

Design

Altecnic expansion vessels are constructed with a high-quality, non-replaceable diaphragm that is resistant to ethylene or propylene glycol mixtures. The vessels are also epoxy coated in Green for corrosion protection. Manufactured in carbon steel with a two or three part weld construction. Pre-pressurised air chamber with synthetic rubber compound bladder. The internal surfaces of the vessel in contact with the water are coated against corrosion.  Altecnic expansion vessels are all tested according to the Pressure Systems Directive.

How It Works

In a closed hot water circuit 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.

Benefits

Altecnic expansion vessels help to maintain constant pressure within the system, while helping to prevent potentially harmful bacteria. Water flows through the vessel, it has a stainless steel connection and thereby meets the ultra exacting hygiene requirements of DIN 1988.
Altecnic expansion vessels are backed by a 5-year warranty.
