The Reflex S 80/10 pressure expansion vessel is designed for closed heating, cooling, and solar systems, where it compensates for the volumetric changes of water due to temperature fluctuations and ensures stable operating pressure of the system. Thanks to its robust construction and high-quality membrane, it reliably protects the system from excessive pressure and reduces the risk of failures in fittings and heat or cooling sources.

The vessel is supplied with a preset gas pre-charge and threaded connection R 1", making it easy to integrate into most standard installations. It is also suitable for systems with glycol-based antifreeze mixtures (approximately 25–50%), making it a versatile solution for modern heating and solar applications.
