Oat coolants

A Coolant Extender can be used with an OAT coolant to top-up certain additives at the products half life which is typically around 480kms. It is the heavy-duty cooling system solution that can extend service intervals and reduce service and maintenance costs. A monomolecular layer of inhibitors is formed on the metal surface only at the anodic sites where corrosion risks to start.

It is our answer to the maintenance demands of heavy duty diesel cooling systems. ES Compleat OAT EG may be used with non-chemical Extended Service. The remaining percent is made of a similar ethylene glycol mixture as conventional coolants. The corrosion inhibitors in OAT coolant are carbon-base opposed to nitrite inhibitors in conventional coolants – and that’s the difference. Conventional corrosion inhibitors in coolant provide excellent protection,.

If a non- OAT engine coolant (antifreeze) is introduced into the cooling system in an emergency, it should be flushed with OAT coolant and replaced with the specified OAT engine coolant (antifreeze) as soon as possible. Do not use water alone or alcohol-based engine coolant (antifreeze) products. OAT MN HD Diesel Extended Life Coolant. This ethylene glycol based product is free of amines, borates, phosphates and silicates.

Its proprietary OAT corrosion inhibitor package DOES NOT contain any 2-EHA. It protects coolant system metals against rust and corrosion and provides excellent high temperature aluminum and wet sleeve liner cavitation protection. It’s designed for use in…. OAT anti-freeze contain ingredients such as 2-EHA, sebacate and other various organic acids.

Unlike green anti-freeze, they generally do not contain silicates or phosphates. Dexcool is an OAT coolant which is not compatible with some of the older antifreezes that are or were on the market. H OAT and OAT are the corrosion protection packages used in antifreeze. Most antifreeze products are ethylene glycol based but there are some antifreezes on the market that are safer around pets and for.

The most well known brand name for OAT antifreeze is Dexcool. A problem with any automotive antifreeze is in the anti-corrosion additives, about of the solution, which are toxic. OAT should not be mixed with other coolants or this can cause corrosions. It sometimes comes in orange or in yellow liquid form. Show More Show Less Compare.

Liter Pink Concentrate Antifreeze. You should not mix OAT based formulas with IAT formulas. OAT -based extended-life coolants. The result is typically turning your coolant into sludge due to a chemical reaction.

Keep in min OAT based formulas are still a developing technology. There are some “universal” formulas that claim compatibility with other IAT. A nitrite-free, phosphate-free, silicate-free and borate-free ethylene glycol-based coolant that uses organic acid technology ( OAT ) for protection of all cooling system metals. Mixing coolants can cause a loss of stability in the corrosion inhibitor, cavitation erosion, and gelling damage.

Best Practices for OAT Coolant. This type of damage is not covered by your warranty, and repairs can cost thousands of dollars. Adding as little as of regular coolant in an OAT system is enough to cause damage to your machine.

This coolant contains added silicates that increase aluminium protection and prevents corrosion. Additives are also present to prevent rusting. These ‘Extended Life Coolants’ (ELC), were usually orange in colour and offered a five-year or 10000-mile change interval. A remaining inhibitor (borate) could attack aluminum if the silicates are depleted.

Blend of premium long-lasting inhibitors provides extended performance. Also for use with cars and light duty trucks with aluminum radiators using extended life coolant. Protects against temperature extremes and the ravages of rust and corrosion. Good for years or 150miles. Different colored antifreeze is used to identify the type of antifreeze being used.

Inorganic Acid Technology (IAT) antifreeze is green in color. Organic Acid Technology ( OAT ) antifreeze is orange, re green, pink or blue. Its non 2-EH ethylene glycol-based formula to provide protection for all cooling system metals. This purple OAT coolant shows to be 10years 150mile coolant.

I just would like to have a extra gallon in the garage for top off. I know the best way to handle this without spending $45-$for a gallon of the correct OAT Coolant. Again, always defer to the owner’s manual. FORMULATIONEthylene glycol based. For best , do not mix with conventional high pH, borate or silicate based coolants.

It is worth noting that some people refer to these as “organic additive technology” (OAT) because the inhibitors which provide the corrosion protection are derived from carboxylic acids. In actuality, the protection is provided by neutralized carboxylic acids called carboxylates. Different manufacturers use different chemical additives to battle rust and corrosion, and they all dye their coolants different colors. GM's ubiquitous DEX-COOL coolant is an OAT antifreeze dyed orange. Such engine coolants are generally referred to as “Hybrids” and typically offer similar life and performance to OAT type coolants , specifically tailored to certain engine types.

Currently the majority of engine coolants are ethylene glycol based.

There is a small percentage of propylene glycol based coolant on the market. OAT coolants typically do not use silicate and phosphate corrosion inhibitors.
