Reflex 140 Litre 6 Bar Heating Expansion Vessel 1" Connection HV140/C

Robust Pressure Management for Large-Scale Heating & Chilled Water Systems

For substantial domestic or commercial applications needing serious pressure control, this Reflex 140 Litre 6 Bar Heating Expansion Vessel is engineered to deliver. It’s a high-capacity solution for managing water expansion in larger sealed heating, solar, or chilled water systems, ensuring stability and protecting equipment.

Essential Pressure Control for Larger Systems

Larger heating systems in extensive homes or commercial settings face challenges managing thermal water expansion. Without adequate provision, pressure can skyrocket, causing leaks and damage. The Reflex 140L Expansion Vessel is indispensable here.

This 140 Litre 6 Bar Expansion Vessel (HV140/C) is built for big jobs. Its 140-litre capacity suits systems in flats, offices, or small hotels, protecting powerful boilers (like Andrews or Morco models) from pressure surges. The 6-bar rating suits higher-pressure systems.

Reflex signifies quality. This Reflex 140L Expansion Vessel is carbon steel with a robust weld construction. It has a pre-pressurised air chamber with a durable synthetic rubber bladder (non-replaceable in this 140L model). Internal surfaces are coated against corrosion; externally, it has a durable blue powder-coated finish. This heavy-duty build ensures a long service life. Proper pressure management also helps pumps (Grundfos, Lowara) and controls (Honeywell, EPH Controls) operate efficiently. Reflex vessels are tested per the Pressure Systems Directive.

Typically installed by professional engineers, the pre-charge pressure must be correctly set. For large projects needing top-tier plumbing solutions and fittings, the correct expansion vessel is fundamental. For smaller systems, see Altecnic Ltd. We also stock components from Danfoss, Polypipe, Gledhill, and Kingspan.
