ANTIFREEZE for heating and cooling systems

A blend of virgin (not recycled) propylene glycol and high purity Triple Protection additives, formulated foruse in closed loop hydronic heating and cooling systems. Cryotek can also be used in radiant tube heating systems, most solar heating systems and geothermal loops. Hercules' exclusive Triple Protectionformula 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 efficientlyby eliminating system deposits, improving heat transfer and minimizing wear to moving parts and seals. Cryotek is compatible with PEX and elastomeric radiant tubing, commonly used materials for seals andbushings and provides corrosion protection for cast iron, steel, copper, brass and solder. Cryotek has not been tested for use in systems containing CPVC plastic. Standard cryotek products should not beused in systems containing aluminum and operating above 160oF/71oC. Cryotek 100/AL is available for aluminum systems. Cryotek should not be used in systems with galvanized piping as the zinc coatingwill be dissolved. Cryotek is a 9498% efficient heat transfer solution in most application dilutions. It has a lower freeze point and higher boiling point than water and is nonflammable, odorless, nontoxic, nonirritating and compatible with Hercules boiler stop leaks and heating system cleaner products.

Cryotek is available in 3 formulations: Cryotek Original Contains virgin (not recycled) propylene glycol with Triple Protection corrosion inhibitor, premixed readyto use formulation. Can be added directly into system undiluted or diluted as required. Certified

* 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 hitTM II to stop leaks on system containing cryotek products.

* Use Hercules boiler & heating system cleaner or sizzle(R) to clean system prior to using cryotek (see

installations instructions).

* 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 contamina tion

of brine or resin bed.

* Cryotek 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 300oF / 150oC. 3. For systems with concentrating solar collectors or evacuated tube solar collectors. 4. In systems containing aluminum and operating temperatures over 160oF / 71oC. (Please check with equipment manufacturer of system to determine compatibility with this product).

CAUTION REGARDING COMPETITIVE PRODUCTS: Hercules cryotek products are formulated using virgin propylene glycol and high purity Triple Protection Additives for assurance of materials compatibility and nontoxicity characteristics. Dilution or mixing of cryotek products with other manufacturers' products may compromise these critical requirements and is not recommended.

INSTALLATION INSTRUCTIONS 1. CLEAN THE SYSTEM It is recommended that any system, whether new or existing, be thoroughly cleaned prior to being charged with cryotek 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. Most boiler manufacturers recommend cleaning new systems with a solution of TriSodium Phosphate (TSP), or Hercules boiler and heating system cleaner (Follow instructions on container). Existing systems need to be flushed and cleaned to eliminate any buildup of rust, scale, lime and other nonorganic matter. These systems should be cleaned with an inhibited hydrochloric acid such as Hercules sizzle (except aluminum systems, check with boiler manufacturer). All systems should be checked for leaks prior to installation of any cryotek product.

2. MEASURE THE TOTAL CAPACITY OF THE SYSTEMusing 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 system piping.

B. Add this number to the gallon capacity of the boiler or equipment in the system to determine the TOTAL SYSTEM FLUID CAPACITY.

TABLE I (Note: 1 US Gallon = 3. 785 Liters)

3. SELECT DESIRED TEMPERATURE COVERAGE Using Table II determine protection level desired and match it to the appropriate cryotek product concentration. TABLE II

4. DETERMINE AMOUNT OF CRYOTEK PRODUCT REQUIRED IN SYSTEM Determine the amount of cryotek product needed in system by multiplying total system capacity in gallons by the concentration factor of cryotek product (first column in each chart above).

Total System Capacity (gal) X Concentration Factor of cryotek Product (%) = Amount of cryotek Product to be used (gal) 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 cryotek product, second add water if necessary. The system can be filled using one of the following two alternatives. The main objective is to fill the system with little or no air trapped in it.

A. After providing for an air exit, pump solution into boiler through the boiler drain valve using a small pump. B. Pour solution through a removed air vent at the HIGHEST point in the system.

6. PURGE THE AIR IN SYSTEM Since air (which includes oxygen) trapped in a system not only results in inefficiencies in the operation of the system (wasted energy and excessive noise), it can also cause corrosion. To prevent this, the system, once filled, needs to be purged of all ai r.

7. TEST THE SYSTEMOnce installed and fully operational, use Hercules Refractometer with Refractometer Reading Adjustment Chart and pH Meter or Cryotek Test Strips to test fluid to assure proper freeze and corrosion protection. Note: An automotive coolant tester will notwork with cryotek or other propylene glycol antifreeze mixtures.

8. MAINTENANCE Systems with cryotek products installed should be tested annually for product concentration and inhibitor levels using Hercules Refractometer with Refractometer Reading Adjustment Chart and pH Meter or cryotek Test Strips. If cryotek product concentration levels are low, add cryotek product using the following formula:

If the corrosion inhibitor tests low, add one 8 oz. container of cryotek Inhibitor for every 20 gallons of fluid capacity of the system. If the total system capacity is less than 20 gallons, add one 8 oz. container of cryotek Inhibitor. If after inhibitor addition and thorough system mixing the corrosion inhibitor still tests low, add another 8 oz. container of cryotek Inhibitor for every 20 gallons of system capacity. If after this addition the inhibitor still tests low, the system should be drained, cleaned, and recharged w ith fresh cryotek.

ADDITIONAL APPLICATIONS FOR TOILETS: Drain tank and bowl then add 1 quart or more of undiluted cryotek Original to each toilet bowl to prevent freezeup. 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 cryotek Original (diluted to desired freeze protection, see Table III) to displace possible water pockets.
