Non-Toxic Anti-Freeze

For heating systems requiring freeze protection as well as corrosion preventive. Hercules cryo-tek™  anti-freeze not only provides this protection, but with its exclusive triple protection inhibitor system, also protects against mineral deposits and mineral sedimentation. A blend of virgin propylene glycol and the triple protection inhibitor package, cryo-tek is designed for use in hydronic heating and cooling closed-loop systems, most solar heating systems, snow melts, radiant heat and general plumbing systems. Use in systems fabricated with metal, plastics (except CPVC) and rubber piping, fittings, seals, and other parts. (Corrosion inhibitors are effective with most metals including steel, aluminum (up to 160º F) and copper. For those boilers with aluminum heat exchangers - see cryo-tek -100/AL on next page.) Non-flammable, odorless, non-toxic, non-irritating, and compatible with Hercules boiler stop-leak and heating system cleaners. (Please note: Minimum flow protection levels are estimated and are dependent on system and equipment. Attempting to circulate fluid below freeze point may overload and/or cause pump failure. Check with system manufacturer for compatibility.)

cryo-tek™ test kit

Made in the USA

Contains 10 color-coded disposable test strips. Each one simultaneously checks level of propylene glycol and level of corrosion protection. Freeze protection levels and corrosion protection levels should be checked annually. Add additional cryo-tek product if freeze protection is inadequate. Add cryo-tek Universal Inhibitor if pH is below 8.5.

cryo-tek™ triple protection universal inhibitor - 
Also available for Aluminum boilers

Made in the USA

Liquid corrosion protection additive. Use to adjust pH of hydronic systems charged with cryo-tek anti-freeze. One bottle will raise pH about one level per 20-gallon content.

Refractometer and PH Meter
Using anti-freeze within the recommended levels of concentration ensures efficiency of heat transfer. Traditional test strips can be difficult to read and are not always accurate. A hand-held refractometer is the fastest and easiest method for ensuring accurate ethylene and propylene glycol as well as battery acid concentrations. A portable electronic pH tester is ideal for checking acidity or alkalinity of heating or potable water systems as well as many other water-based solutions on the work site.
