Expansion vessel 33 l. for open system

The expansion vessel is an integral part of radiator-based hot-water heating for premises with directly and indirectly fed circuits. Expansion vessels are made in different volumes so that the most suitable one can be chosen depending on the size and number of radiators.
To monitor whether the system is always full, all expansion vessels are equipped with a level gauge tube, so that it can be topped up when necessary. The expansion vessels are connected to the system via a ½ nipple.

For installation only on open feed systems that are unpressurised!
