Pressurized Solar Thermal System Basics | Solar365
A pressurized system should really be referred to as a "closed-loop pressurized antifreeze solar thermal system" – the two-word version is much simpler and more common! Pressurized systems are the most flexible type of solar hot water installation and, consequently, are the most common worldwide.
A range of extreme temperature rated solar heat transfer fluids (solar fluid) with antifreeze function, for use in solar thermal hot-water systems, both commercial and domestic. To prevent internal corrosion, scaling and biological fouling all Solaris products are formulated with reversibly evaporisable inhibitors which exceed ASTM D1384 standards.
What To Consider When Selecting Antifreeze for Heating Systems
Solar System antifreeze is specifically designed for solar water heating systems. It provides excellent freeze protection while maintaining the efficiency of the solar water heating system. It can also be used in radiant tube heating systems and geothermal loops and is compatible with PEX and elastomeric radiant tubing.
