ANTI-FREEZE for heating and cooling systems
TM
The virgin propylene glycol used in cryo-tek -100/AL and all cryo-tek products 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, chillers, ice melt, solar heating systems, and
general plumbing systems that require freeze protection. Cryo-tek -100/AL is specifically formulated for aluminum based heat
exchangers.
Add cryo-tek product to protect pipes from freezing and bursting. Although cryo-tek -100/AL is specifically designed for use in boil-
ers with aluminum heat exchangers, it can be used in more traditional applications, such as 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 hit
TM
II to stop leaks on system containing cryo-tek products.
 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.
(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 -100/AL. 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. Existing systems need to be flushed and cleaned to
eliminate any build-up of rust, scale, lime and other non-organic matter. All systems should be checked for leaks prior to installation of any
cryo-tek product. Minor leaks can be sealed with Hercules base hit II or Hercules boiler liquid.
* For special applications which may not be covered on this or other Hercules literature, please contact Hercules Technical Services Department by phone at
