PRO-TEK®-100 is an inhibited propylene glycol-based industrial heat transfer fluid and antifreeze that contains food-grade corrosion inhibitors. It is suitable for use in potable water systems. PRO-TEK®-100 is designed to provide freeze and burst protection, excellent thermal conductance, protection against corrosion and fouling and long-term stability in closed recirculating water loops. PRO-TEK®-100 provides burst protection to -100 deg F. Freeze points and burst points are controlled by the propylene glycol to water ratio.
