KOOL FROST-96(FFG)

Pre-Inhibited Propylene Glycol

Anti-Corrosive/Inhibited Propylene Glycol Based Antifreeze Concentrate

Pre-Inhibited Propylene Glycol is a high-purity heat transfer and antifreeze fluid formulated with advanced corrosion inhibitors to protect metal surfaces in HVAC systems, chillers, refrigeration units, solar heating systems, and industrial cooling applications. Designed to prevent rust, scale formation, and system degradation, this ready-to-use glycol solution enhances thermal efficiency, extends equipment lifespan, and reduces maintenance costs. Suitable for use in closed-loop systems, it offers excellent freeze protection, low toxicity, and long-term stability. Ideal for commercial and industrial applications, Pre-Inhibited Propylene Glycol ensures reliable performance, superior corrosion control, and optimal heat transfer efficiency.

Kool Frost-96 is industrially inhibited Propylene glycol based antifreeze concentrate which utilize a unique corrosion inhibitor package made from non-toxic raw materials. These inhibitors offer superior corrosion protection for most metals including carbon steel, brass, copper, stainless steel, cast iron and many other alloys by creating a passive layer on the surface that contacts the Kool Frost-96 and prevents corrosion. It also stabilizes the pH of the fluid, keeping it in the range that is suitable for the metals in the system. Kool Frost-96 is recommended for use in application where oral toxicity is important or where incidental contact with drinking water is possible. Since the toxicity of heat transfer fluids may be adversely altered in chilling systems, used fluids should be handled with reasonable care.

Causes of Corrosion
Normal Propylene Glycol oxidizes when exposed to air and heat resulting formation of organic acids viz. Glycolic acid, Oxalic acid, Glyoxylic acid and Formic acid etc. These acids then chemically attack and corrode the system metal causing metal loss, pitting and pin hole etc. The corrosion rate of CO2 is a function of partial pressure, temperature, Chloride presence in water and the type of material. There is no corrosion mechanism more damaging on a concentration basis than O2 – small amount of O2, water and chlorides can damage the pipe within a few months.
