ANTI-FREEZE FOR HEATING
AND COOLING SYSTEMS
TECHNICAL SPECIFICATION
DESCRIPTION
• 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 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 Original contains virgin (not recycled) propylene glycol
with Triple Protection corrosion inhibitor, pre-mixed ready to use
formulation. Can be added directly into system undiluted or diluted as
required. Certified Performance: Freeze Protection Down to -22°F/-
30°C, Pumpable Down to -27°F/-33°C, and Burst Protection Down to
-80°F/-62°C. Cryo-Tek Original can be further diluted with water for
less severe conditions.(see Table II)
*Please check with equipment manufacturer of system to determine
compatibility with this product.
**Minimum flow protection levels are estimated and are dependent on
system and equipment.

APPLICATION/USES
• 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 .
• *For special applications which may not be covered on this or other
Oatey literature, please contact Oatey Technical Services Department

APPROVALS AND LISTINGS
The virgin propylene glycol used in Cryo-Tek is “GRAS” (Generally Recognized
As Safe) for incidental contact with food.
Test Kits and Accessories
Freeze protection levels and corrosion protection levels should be checked
annually. Use Hercules Refractometer and pH Meter. Add additional
Cryo-Tek product if freeze protection is inadequate. Add Oatey
approved Corrosion Inhibitor if pH is below 8.5. (see Maintenance)
