CRYO-TEK™ AG Date: August 2017
Anti-Freeze for Heating and Cooling Systems
APPROVALS & LISTINGS
The virgin propylene glycol used in Cryo-Tek is “GRAS” (Generally Recognized As Safe) for incidental contact with food.
SPECIFIC 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
SPECIFIC APPLICATIONS*
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 by phone 1-800-321-9532, or fax 1-800-321-9535, or visit our technical database web-site at www.Oatey.com.
* 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.
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 AG
A concentrated virgin (not recycled) propylene glycol with Triple Protection corrosion inhibitor, which
can be diluted with water to desired protection levels. (see Table II)
Test Kits and Accessories
Freeze protection levels and corrosion protection levels should be checked annually. Use Hercules Refractometer
(35290) and pH Meter (35272). Add additional Cryo-Tek product if freeze protection is inadequate. Add
Sludgehammer Universal Corrosion Inhibitor (35297) if pH is below 8.5. (see Maintenance)
