Cryo-tek-100/AL is anti-freeze specifically intended for boilers with aluminum heat exchangers. According to the manufacturer, the antifreeze is formulated and blended from only pure virgin propylene glycol and high-purity triple protection additives. The company says that triple protection benefits not found in competing products are an acid neutralizer (for corrosion protection), mineral deposition preventative (chelate agent), and mineral sediment preventative (a scale inhibitor).
