†
Dissolved carbon dioxide calculation is from the pH and total alkalinity values shown below or measured on the site
using a test kit. Dissolved Carbon Dioxide, PPM = TA x 2
CA UT IO N :
When your application requires the use of glycol, use industrial
grade glycol specifically designed for heat transfer systems and equipment. Never
use glycol designed for automotive applications. Automotive glycols typically have
additives engineered to benefit the materials and conditions found in an automo-
tive engine; however, these additives can gel and foul heat exchange surfaces
and result in loss of performance or even failure of the unit. In addition, these
additives can react with the materials of the pump shaft seals resulting in leaks or
premature pump failures.
WA R NIN G :
Ethylene Glycol is flammable at higher temperatures in a vapor state. Carefully
handle this material and keep away from open flames or other possible ignition
sources.
