What's Included

• 1 x Altecnic Reflex 12L Heating Expansion Vessel

The Altecnic Reflex 12L Heating Expansion Vessel is designed to maintain stable pressure in sealed heating systems, helping to protect components and ensure efficient operation. Suitable for a wide range of domestic and light commercial applications, this compact 12 litre vessel provides dependable performance and long-term reliability.

Durable Diaphragm Design

The vessel features a non-replaceable synthetic rubber diaphragm that separates air and water, allowing for safe expansion as system temperatures rise. The diaphragm and vessel halves are secured with a crimped collar, ensuring a pressure-tight seal across the unit.

Nitrogen Pre-Charged for Consistent Performance

Supplied factory pre-charged to 1.5 bar with nitrogen, the vessel provides stable operation and reduced maintenance. Nitrogen filling helps minimise pressure fluctuations and improves long-term performance.

Robust Construction

Finished in a grey powder epoxy coating, the vessel is protected against corrosion and wear. It is designed to withstand demanding system conditions, including high temperatures and glycol mixtures.

Designed for Heating System Compatibility

The expansion vessel is suitable for flow temperatures up to 120°C and is resistant to ethylene and propylene glycol mixtures. It is manufactured in accordance with the Pressure Equipment Directive and meets BS EN 13831:2007 standards for closed expansion vessels.
