80L SOLAR RATED EXPANSION VESSEL

80-litre solar-rated expansion vessel designed for closed-loop solar thermal and heating circuits. It absorbs thermal expansion in water/glycol mixtures to stabilise system pressure and protect components such as pumps, collectors, and pipework.

Manufactured by Altecnic Ltd, it features a high-temperature resistant membrane suitable for solar applications, a durable steel shell with protective coating, and a Schrader valve for pre-charge adjustment. Install vertically and size/set the pre-charge to suit your system design.

For non-potable circuits only. Use with appropriate mounting, isolation, and safety devices. Refer to the manufacturer’s data sheet for exact pressure, temperature, and connection specifications.
