Blending Instructions Using Penray Inhibitors

FOR CONVENTIONAL TECHNOLOGY – PENRAY 2792 and 2797

ONE:  Bulk Penray Inhibitors should be well agitated before and during addition to the glycol. This will ensure that the antifoam, which tends to float, is mixed thoroughly. This is especially important when blending antifreeze for sale in the state of Florida , which tests antifreeze by running the foam test.
TWO: Fill blend tank with the amount of glycol necessary for batch.  Good agitation of the glycol is essential.  A mixer or air sparge can be used. Agitation of the glycol MUST be started well BEFORE adding the Penray Inhibitor.
THREE: DO NOT exceed the following addition rates of the inhibitor into the glycol:

Batch Size (gals) Addition Rate Per Minute
5,000 0.8 gals or 8 lbs.
10,000 1.6 gals or 16 lbs.
15,000 2.4 gals or 24 lbs.
20,000 3.2 gals or 32 lbs.
25,000 4.0 gals or 40 lbs.
30,000 5.0 gals or 50 lbs.

This translates into a total addition time of a little over 2 hours. Accidentally adding too fast can be avoided by using a narrow line (1″) and a low power pump. After the addition, the batch should be blended until the TA is in specification.  Adding the inhibitor too quickly or with inadequate agitation of the glycol can lead to silicate dropout.

FOURPenray inhibitor concentrates should NEVER be pre-blended into less than the final volume of glycol or have glycol added to them.
FIVE: While packaging, the antifreeze batch should be well agitated. This will ensure that each jug of antifreeze contains the proper amount of antifoam.
