Hercules Cryo-Tek-100 Anti-Freeze Heating & Cooling System, 5 Gal, Red

A blend of virgin (not recycled) propylene glycol and high purity Triple Protection additives, formulated for use in closed loop hydronic heating and cooling systems. Cryo-tek can also be used in radiant tube heating systems, most solar heating systems and geothermal loops. Hercules’ exclusive Triple Protection formula stabilizes pH to prevent acid corrosion, chelates hard water minerals and inhibits the formation of scale and sediment. These components work together to keep the system clean and operating efficiently by eliminating system deposits, improving heat transfer and minimizing wear to moving parts and seals. Cryo-tek is compatible with PEX and elastomeric radiant tubing, commonly used materials for seals and bushings and provides corrosion protection for cast iron, steel, copper, brass and solder. Cryo-tek has not been tested for use in systems containing CPVC plastic. Standard cryo-tek products should not be used in systems containing aluminum. Cryo-tek -100/AL is available for aluminum systems. Cryo-tek should not be used in systems with galvanized piping as the zinc coating will be dissolved. Cryo-tek is a 94-98% efficient heat transfer solution in most application dilutions. It has a lower freeze point and higher boiling point than water and is non-flammable, odorless, non-toxic, nonirritating and compatible with Hercules boiler stop leaks and heating system cleaner products.

Cryo-tek -100: Contains virgin (not recycled) propylene glycol with Triple Protection corrosion inhibitor, pre-mixed ready to use formulation.
