Zilmet Volumiser Vessels / Intermediate Vessels
The VSG Vessels are tailor-made for Solar Thermal Systems and serve as a buffer for un-circulated liquid. This buffer helps to manage the expansion and contraction of the fluid as it heats and cools. The buffer contains cooler water which comes into direct contact with the main expansion vessel, preserving the membrane's integrity due to the lower temperature. It's crucial to determine the correct vessel size and have it installed by trained professionals before installation.

Installation Siting
It may be necessary to fit an Intermediate VSG V essel between the Solar Thermal Circuit and the Primary Solar vessel in order to lower the temperature of the liquid in direct contact with the SOLAR PLUS membrane.
