Application
Use Pro-Tek PG PLU™ to winterize boilers, cooling towers, fire hydrants and sprinklersystems, hydronic heating and solar systems, ground source heat pumps, refrigeration, snow melt and ice making systems, industrial heat transfer, pipe tracing and coil defrosting, plumbing applications including winterizing RV’s, boats, and summer homes.
Purpose
ProTek-PG™ PLUS is a concentrated heat transfer fluid containing 95% propylene glycol. It is designed to provide freeze and burst protection, excellent thermal conductance, protection against system corrosion and fouling, and long-term system stability in closed recirculating water loops.
Advantages
ProTek-PG™ PLUS is formulated from GRAS virgin propylene glycol, food-grade corrosion inhibitors, and anti-foaming agents. It is safe to use in systems where incidental contact with potable water may occur. It is compatible with the corrosion and scale inhibitors used in closed loops, cooling towers and boilers. ProTek-PG™ PLUS has an operating range of -70°F to 235°F. ProTek-PG™ PLUS is a concentrated propylene glycol heat transfer fluid. Therefore, it must be mixed with a minimum of 25% water to provide the desired freeze and burst protection. ProTek-PG™ PLUS is safe for use in PEX tubing.
