A new generation of very efficient boilers utilizing ALUMINUM HEAT EXCHANGERS are becoming

more popular in today's marketplace. These new boilers typically heat three times faster than traditional

boilers and require a specific, unique blend of anti-freeze specific to protecting against acid corrosion.

Cryo-tek -100/AL is a blend of virgin (not recycled) propylene glycol and Hercules exclusive

Triple Protection additives designed for use in hydronic heating and cooling closed loop piping

systems (including PEX and radiant tube heating systems), ice melt and general heating

systems where aluminum heat exchangers are installed.

Hercules Triple Protection additives provide outstanding protection against acid corrosion, scale

and sedimentation formation in properly maintained systems containing recommended

concentrations of cryo-tek Anti-Freeze.

 Acid neutralizing agent protects by neutralizing corrosive acids.

 Mineral Deposition Preventative eliminates scale formation on critical heat transfer surfaces, piping

systems and equipment.

 Mineral Sediment Preventative keeps minerals in solution, resisting formation of clusters of mineral

salts and preventing particles from precipitating out of solution.

Used at recommended levels, all three agents work together to prevent bio film (slime) build-up.

Cryo-tek -100/AL may be used in systems fabricated with metal, plastics (except CPVC) and rubber

piping, fittings, seals, and other parts. Corrosion inhibitors in all cryo-tek products protect against

corrosive build-up within the piping loop and are effective with most metals including steel,

aluminum* and copper. Cryo-tek solutions have a high specific heat and are efficient at transferring

heat.

As packaged, cryo-tek is non-flammable, odorless, non-irritating, and compatible with Hercules

boiler stop leaks.

Formulated for the maximum propylene glycol protection directly out of the container. Certified

Performance: Freeze Protection Down to -60°F / -51°C, Pumpable down** to

-70°F / -57°C, and Burst Protection Down to -100°F / -73°C.

Cryo-tek -100/AL can be diluted with water for less severe conditions. (See Chart page 3.)

ANTI-FREEZE for aluminum heat exchanger

heating and cooling systems

Test Kits and Accessories

Freeze protection levels and corrosion protection levels should be checked annually. Use Hercules

Refractometer (35290) and pH test Meter (35272) or, cryo-tek Test Kit (35271). Add additional

cryo-tek product if freeze protection is inadequate. Add cryo-tek

–100/AL Inhibitor (35274) if pH is below 7.0. (see Maintenance, page section)

* 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.

2. MEASURE THE TOTAL CAPACITY OF THE SYSTEM using one of the following methods: DIRECT METHOD A. Fill system completely, making sure all components of system are full. B. Shut system down, let pressure drop to a safe level. C. Drain out fluid into suitable container and record the number of gallons removed. This is TOTAL SYSTEM FLUID CAPACITY. ESTIMATION METHOD A. Determine system pipe sizes and amount of linear footage for each size. Using Table I, calculate the volume of the steam piping. B.

ANTI-FREEZE for heating and cooling systems 8. MAINTENANCE (Con’t) Be sure to drain adequate fluid from system before adding the additional Cryo-tek -100/AL. The proprietary inhibitor used in Hercules Cryo-tek -100/AL has an exceptionally long life expectancy. The pH of the system solution should always be between 7.0 and 8.5. If the corrosion inhibitor tests low, add one 8 oz.
