Industrially Inhibited Propylene Glycol

PROTOCOL NT is a nontoxic heat transfer fluid developed for a multitude of industrial service applications requiring a propylene glycol based coolant for a broad temperature range. Our NoPit inhibitor package contains organic and inorganic inhibitors for corrosion protection of single or mixed metallurgy systems. In addition to protecting ferrous, as well as nonferrous metals, the NT series also contains additional buffers for a higher reserve alkalinity level. The high reserve alkalinity of PROTOCOL NT ensures the neutralization of organic acids formed by glycol's and extends the service life of the fluid.
