Product Details
Comstar's Profrost I-40 is a premium industrial coolant composed of 40% pre-diluted propylene glycol with a corrosion inhibitor package designed to prevent system corrosion and clog-ups caused by chemicals and minerals in operating systems. This food-quality propylene glycol is intended for systems that may be utilized in food and/or pharmaceutical processing, though it is not intended as an additive for food or pharmaceuticals. The product addresses the issues posed by common tap water's acidity, which can corrode metal components and contribute to lime/scale deposits that impair heat transfer and clog pipes. Profrost I-40 is non-toxic, non-irritating, biodegradable, and designed with a corrosion inhibitor that protects against corrosion and clogging. This product is ready to use, prediluted at 40% propylene glycol.
