CRYO-TEK™ ORIGINAL 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 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)

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)

SPECIFICATIONS: Cryo-Tek™ Original ADDITIONAL APPLICATIONS FOR TOILETS: drain tank and bowl then add 1 quart or more of undiluted Cryo-Tek Original to each toilet bowl to percent freeze-up. FOR BOATS AND TRAILERS: For boats and trailers with pressurized hot water systems, see TABLE III. For these systems, disconnect water tank and join inlet and outlet to form a bypass. Drain water tank thoroughly and add Cryo-Tek Original (diluted to desired freeze protection, see Table III) to displace.

SPECIFICATIONS: Cryo-Tek™ Original DIRECTIONS FOR USE 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.

SPECIFICATIONS: Cryo-Tek™ Original 5. CHARGING THE SYSTEM System should be completely empty with burner and pump shut off. All internal valves, including zone valves, should be open. THE ENTIRE SYSTEM SHOULD BE OPEN TO PREVENT ANY AREA OF IT FROM BEING ISOLATED. First, add the computed amount of Cryo-Tek product, second add water if necessary. The system can be filled using one of the following two alternatives. The main objective is to dill the system with little or no air trapped in it. 6. A.
