50L SOLAR RATED EXPANSION VESSEL

The 50L Solar Rated Expansion Vessel from Altecnic Ltd is designed for sealed solar thermal systems to accommodate the expansion of heat-transfer fluid as temperatures rise. It helps to stabilise system pressure, protect components such as pumps and collectors, and reduce the risk of safety valve discharge during peak operating conditions.

Constructed with a high-temperature resistant diaphragm suitable for glycol-based solar fluids, the vessel features a durable steel shell and a factory pre-charge that can be adjusted to suit the system. It is intended for closed-circuit solar thermal applications in domestic or light commercial installations.
