The majority of Great Western Glycol's bulk coolant/antifreeze sales are for "pre-diluted" ready-to-use products, blended with one of three primary corrosion inhibitors.
Great Western Glycol can package these products in drums, totes, or provide bulk fills of up to 5,000 gallons per delivery.
Conventional Green Heavy Duty 50/50
Inorganic Antifreeze, the former mainstay of the antifreeze world, is still available in a more modern blend that is compatible with conventional green antifreeze/coolant blends. Our blend contains nitrite, and is appropriate for both light duty and heavy duty applications.
Light-Duty Poly Organic (POAT) 50/50
This formulation contains a pure OAT inhibitor package, and is compatible with coolants such as Dex-Cool™ and nearly every OE antifreeze/coolant currently on the market. A proprietary blend of OAT chemicals provide exceptional all metals protection, including aluminum-intensive cooling systems.
Great Western Glycol can provide any of these formulations as a concentrated product or a specified glycol percentage. Additionally, as Great Western Glycol is a custom blender of glycols, our expert staff can help to formulate the appropriate product and corrosion inhibitor for nearly every heat transfer or freeze protection application, utilizing PG, EG or Glycerin.
Gold Hybrid Organic Acid (Nitrited HOAT) 50/50
The inhibitor formulation for our Gold product contains a combination of Organic Acid Technology (OAT) chemistry, with some inorganic chemicals including nitrite. This product complies with the G-05 specification and is extremely popular with "mixed fleet" operators, as it has a longer life and is appropriate for both light duty and heavy duty vehicles.
Heavy-Duty Poly Organic (POAT) 50/50
This is our most robust, long-life product, with a higher concentration of multiple OAT corrosion inhibitors to provide extended life protection for heavy-duty applications, including off-road equipment.
