HEAT TRANSFER FLUIDS

PRODUCTS PLUS, INC. heat transfer fluids blend readily with both ethylene and propylene glycol and provide corrosion prevention, fluid longevity, and consistent finished product quality. 

The inhibitors in PROPYLENE PLUS protect all metals found in heat transfer fluid systems. These inhibitors control the corrosion of metals, help prevent scaling and fouling of heat transfer surfaces and buffer the pH to maintain it in the optimum operating range. The inhibitor system is based on a high-phosphate, multi-component formulation which makes Propylene Plus equivalent in terms of functionality and performance to the very best national brands available. The finished fluid has a recommended operating temperature range of -60ºF to +350ºF (-50°C to 120°C), and can be used to provide both freeze and burst protection for systems which may be exposed to very low temperatures. 

PROPYLENE PLUS provides outstanding corrosion protection for copper, brass, solder, steel, and cast iron and aluminum. The finished fluids made with PROPYLENE PLUS meet or exceeds ASTM D1384, the standard industry corrosion test for these metals. It is compatible with most plastics, elastomers and types of rubber. Its corrosion protection system includes organic acid technology which coats iron, steel and aluminum metal surfaces to protect them from acidic attack and rust formation with a thin molecular coating that doesn’t cause fouling or significantly reduce heat conduction through the metal heat transfer surfaces. PROPYLENE PLUS also contains tolytriazoles to protect copper, brass and solder from attack and oxygen scavengers to provide further protection from rust and pitting. A very effective buffering system neutralizes acids formed by the normal thermal and oxidative degradation of glycols, thus maintaining the pH in its optimum range. 

Finished fluids containing PROPYLENE PLUS may be formulated to any concentration. Water used to dilute the fluid can be low-hardness, city water or well water, although the use of deionized water is best. It is recommended that water with no more than 350 ppm hardness be used to dilute the concentrate or be used as make-up water. Higher hardness levels may cause excessive inhibitor consumption, scale deposits, and metal pitting.
