I want to add treatment chemicals into my facility.

The anti-freeze you use has undergone a series of development studies designed by manufacturer.  Its corrosion inhibitors have been assessed and validated in the course of a number of corrosion tests.  There is therefore no need to add other products.  Furthermore, the addition of other products could destabilise the formulation of the glycolated water and reduce the effectiveness of the corrosion inhibitors in the anti-freeze.
