Product Overview

50% Propylene Glycol Inhibited is a pre-mixed, industrial-grade heat transfer fluid engineered for superior thermal management in closed-loop systems. Also known chemically as inhibited Propane-1,2-diol, this solution combines the freeze protection properties of propylene glycol with a specialized inhibitor package designed to prevent corrosion in ferrous and non-ferrous metals.

Designed specifically for HVAC systems, industrial chillers, and process cooling circuits, this 50% aqueous solution provides a balance of efficient heat transfer and pumpability. The added inhibitors stabilize pH and passivate metal surfaces, significantly extending the service life of equipment compared to uninhibited glycols. It is compatible with standard piping materials, including copper, steel, and stainless steel, as well as HDPE containment.
