The virgin propylene glycol used in cryo-tek is “GRAS” (Generally Recognized As Safe) for incidental contact with food.
Use any cryo-tek Anti-Freeze in hydronic closed loop heating and cooling systems, solar heating systems, and general plumbing
systems that require freeze protection. Operating Temperature Range for Closed System: Up to 250°F
Add any cryo-tek product to protect pipes from freezing and bursting. Also prevents freeze-ups in chiller systems, recreational
vehicles, seasonal homes, mobile homes, trailers, boats, sprinkler systems, and industrial use.

Read all cautions and directions carefully before using this product.
Not for use in steam systems.
Not for use with CPVC pipe and fittings.
Use Hercules boiler liquid or base hitTM II to stop leaks on system containing cryo-tek products.
Use Hercules boiler & heating system cleaner or sizzle® to clean system prior to using cryo-tek (see installations instructions).
Do not use in internal combustion engines as a coolant.
Do not use in water softeners. Disconnect all water softeners from system or provide back flow protection to prevent contamination
of brine or resin bed.
Cryo-tek Products are not recommended: 1. For use in systems containing galvanized components. 2. For open solar systems and
systems where operating stagnation temperatures are regularly over 300°F / 150°C. 3. For systems with concentrating solar
collectors or evacuated tube solar collectors. 4. In systems containing aluminum.
(Please check with equipment manufacturer of system to determine compatibility with this product).
CAUTION REGARDING COMPETITIVE PRODUCTS:
Hercules cryo-tek products are formulated using virgin propylene glycol and high purity Triple Protection Additives for assurance of
materials compatibility and non-toxicity characteristics. Dilution or mixing of cryo-tek products with other manufacturers’ products may
compromise these critical requirements and is not recommended.
1. CLEAN THE SYSTEM - It is recommended that any system, whether new or existing, be thoroughly cleaned prior to being charged with
cryo-tek products. Any system contaminated with dirt and other materials reduces efficiency and wears the system prematurely. New
systems need to be free of flux, solder residue, grease and any foreign particles. Most boiler manufacturers recommend cleaning new
systems with a solution of Tri-Sodium Phosphate (TSP), or Hercules boiler and heating system cleaner (Follow instructions on
container). Existing systems need to be flushed and cleaned to eliminate any build-up of rust, scale, lime and other non-organic matter.
These systems should be cleaned with an inhibited hydrochloric acid such as Hercules sizzle (except aluminum systems, check with
boiler manufacturer). All systems should be checked for leaks prior to installation of any cryo-tek product.
* For special applications which may not be covered on this or other Hercules literature, please contact Hercules Technical Services Department by phone at
1-800-221-9330 or send a fax to 1-800-333-3456.
