PROTOCOL heat transfer fluids are chemically engineered to provide superior corrosion protection by utilization of our neutralized-organophosphorous-inhibitor-technology. Our NoPit inhibitors will passivate system metals without fouling critical heat transfer surfaces. In addition to protecting ferrous and non-ferrous metals PROTOCOL coolants contain specially formulated buffers designed to give the fluid a higher level of reserve alkalinity; The increased buffering capacity of PROTOCOL Heat Transfer Fluids ensures the neutralization of organic acids formed by glycol's exposed to high system temperatures and/or air.
