Sunset Solar antifreeze

(This text is machine translated) Sunset Solar Antifreeze protects your solar array from freezing temperatures. This frost-resistant heat transfer medium is required because the system is also operated at temperatures below 0°. The antifreeze LIQUID sun concentrate is based on monopropylene glycol. You will receive a colorless and odorless liquid with freeze and corrosion protection, which is also non-toxic and food-safe. If you dilute the concentrate with water in a ratio of 1:1, you are guaranteed frost protection down to minus 28°C.
