In high-performance solar thermal systems, temperatures can often exceed the safety limits of standard expansion vessel membranes. The Varem SOLAR PRE-TANK (Intermediate Vessel) is the professional solution to this problem.
Acting as a thermal buffer, this double-connection storage tank is installed between the solar collector and the expansion vessel. It provides extra volume for the solar fluid to cool down before it reaches the expansion tank’s membrane, preventing premature wear, cracks, and system failure caused by overheating.
Why Use a Solar Pre-Tank? Solar systems can reach stagnation temperatures that are dangerously high. Without a pre-tank, the hot glycol can degrade the rubber membrane of your main expansion vessel. The SOLAR PRE-TANK absorbs this thermal shock, ensuring your system remains pressurized and safe for years to come.
