JEFFCOOL® P150 Inhibited Propylene Glycol is an inhibited propylene glycol based industrial coolant and heat transfer agent. It is a slightly hazy liquid, free of suspended solids with a slight odor. The inhibitor system is designed to protect brass, copper, solder, steel, cast iron, aluminum, and other metals commonly found in industrial cooling and heating systems. A foam inhibitor is included to minimize foaming tendencies during service.

The effectiveness of JEFFCOOL® P150 Inhibited Glycol in preventing corrosion has been proven in extensive laboratory simulations and in actual service tests. Using JEFFCOOL ® P150 Inhibited Propylene Glycol for heat transfer applications in place of brine solutions or uninhibited glycol-water solutions lowers maintenance costs and improves heat transfer.



Since JEFFCOOL® P150 Inhibited Glycol is formulated with propylene glycol, it is especially suitable for applications in which toxicological and environmental considerations are critical. JEFFCOOL® P150 Inhibited Propylene Glycol(s) is compatible and completely interchangeable with systems currently utilizing ethylene glycol based coolants.

JEFFCOOL® P150 Inhibited Propylene Glycol(s) protects cooling systems from freezing in winter, overheating in summer, and corrosion in all seasons. Improved heat transfer and less internal corrosion contributes significantly to overall operating and maintenance costs. JEFFCOOL® P150 Inhibited Glycol(s) is recommended as a heat transfer fluid for line heaters, ground thawing, athletic fields, grave digging, snow melting systems for loading ramps, walkways, highways, and airfield runways. The corrosion protection provided by JEFFCOOL® P150 Inhibited Propylene Glycol and its low toxicity level as compared to other heat transfer fluids makes it an ideal transfer medium for heating, ventilation, and air conditioning (HVAC) systems as well as solar energy collection systems.

Thermal Energy Storage, Heating and Cooling Systems

JEFFCOOL® P150 Inhibited Glycol(s) is recommended as a heat transfer fluid in combination heating and cooling systems for large buildings. The excellent corrosion protection afforded by JEFFCOOL ® P150 Inhibited Glycol prolongs the life of the piping in these systems. JEFFCOOL ® P150 Inhibited Propylene Glycol(s) is also an excellent heat transfer medium for continuously wetted solar energy collection systems.
