Altecnic 2L Potable Water Vessel – Reflex Mini

Altecnic 2L Potable Water Vessel – Reflex Mini, Grey (MPN: PV2M) is a compact potable expansion vessel for sealed unvented hot and cold water systems. It provides a pre‑pressurised air chamber to accommodate thermal expansion, helping to protect pipework, fittings, valves and cylinders from over‑pressure.

Key Features

• 2 litre capacity – ideal for domestic and small commercial potable water systems, commonly used with undersink water heaters and small unvented cylinders.
• Potable‑grade construction – designed specifically for drinking water applications with a potable water membrane and WRAS approval.
• Durable carbon steel shell – robust body with a grey powder‑epoxy coating for long‑term corrosion resistance.
• Fixed Butyl membrane – synthetic rubber diaphragm separates water and air, maintaining stable pre‑charge pressure and reliable performance.
• Compact, lightweight design – vertical Reflex Mini format for easy installation in tight spaces such as under sinks or in cupboards.

Typical Applications

• Sealed domestic hot water systems – provides expansion volume on unvented cylinders, point‑of‑use heaters and booster sets.
• Undersink water heaters – commonly paired with small electric water heaters to manage expansion on the cold inlet.
• Small commercial potable systems – cafes, offices and washroom areas where a compact potable vessel is required.
