Solar Antifreeze
Our products revolutionize energy storage solutions for base stations, ensuring unparalleled reliability and efficiency in network operations.
Most solar thermal systems use antifreeze as the liquid to transport heat from the solar panel to the cylinder. However, there are a few drain back systems that only use water. The antifreeze is normally non-toxic propylene glycol (as opposed to toxic ethylene glycol). An antifreeze change may be required for your solar system.
