PROTOCOL Heat Transfer Fluids are chemically engineered to provide superior corrosion protection through the utilization of our neutralized organophosphorous inhibition 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 glycols exposed to high system temperatures and/or air.
