The ecological antifreeze-thermal fluid Proflu48 is the ideal solution for protecting solar systems during the winter months. It is specially designed to prevent the freezing of water circulating in the collectors, thus ensuring the long-term operation and durability of your installation. Proflu48, based on non-toxic propylene glycol, offers safe and effective protection, preventing potential damage and breakages caused by low temperatures. The correct amount of fluid in the circuit is crucial, and it should be replaced during every scheduled maintenance.
