The SOLARVAREM CE is the professional’s choice for solar heating systems. In solar applications, expansion tanks are exposed to much harsher conditions than in standard heating—including higher temperatures and chemical additives. Varem has engineered this vessel to meet those challenges head-on.
At the heart of the vessel is a specialized solid membrane designed to remain flexible and airtight even when exposed to 100% glycol concentrations. The addition of a screwed stainless steel flange eliminates the most common point of failure—corrosion at the connection point—making this one of the most durable vessels on the market.
Technical Excellence for Solar Professionals:
Max Temperature: +130°C (Peak).
Max Pressure: 10 Bar (models starting from code R8...281).
Flange Material: High-grade Stainless Steel (FIRD series).
Pre-charge Pressure: 2.5 Bar (standard for solar).
Application: Solar thermal systems, solar water heating, and high-temp closed circuits.
Color: Classic Varem Red.
 
Note: For the 5L model, CE certification is not applicable due to its compact volume, yet it is built to the same rigorous quality standards as the larger units.
