Select Desired Temperature Coverage
Using Table II, determine the desired protection level and match it to the appropriate Cryo-Tek product
concentration.
Note: The percentages listed in the chart refer to the amount of Cryo-Tek solution and not the
actual percentage of glycol. (For example: 50% of the -100 is 27.5% glycol)

Determine Amount of Cryo-Tek Product Required in System
Determine the amount of Cryo-Tek product needed in the system by multiplying total system capacity in
gallons by the concentration factor of Cryo-Tek product (rst column in each chart above).
Total System Capacity (gal.)× Concentration Factor of Cryo Tek Product
(%)=Amount of Cryo Tek Product to be used (gal.)
