Havoline Extended Life Corrosion Inhibitor


Description

Havoline Extended Life Corrosion Inhibitor (Havoline XLI) is a low-toxic, environmentally friendly inhibitor concentrate. Based on patented aliphatic acid technology, Havoline XLI provides long-life corrosion protection in aqueous solutions for all engine metals, including aluminium, iron, copper and solder alloys. 

Mixed with the appropriate amount of water, Havoline Extended Life Corrosion Inhibitor is recommended as a coolant, flushing fluid or hot test fluid for engine blocks and all cooling systems. During extensive field testing, the synergistic combination of mono- and di-carboxylic acid has proven to provide superior protection for at least 32,000 hours in marine and stationary applications. The product is compatible with glycol-based engine coolants. Its is recommended to change the coolant every five years or at above operating times, whichever comes first.

Benefits

Havoline XLI offers a lot of benefits to the engine designer as well as to the user :

• Extended & superior corrosion protection by synergistic combination of additives.

• Superior technology provides more flexibility to engine design.

• Excellent protection of thermostat, radiator and waterpump.

• Reliability depletion free and stable inhibitor.

• Improved hard water stability absence of silicates and phosphates.

• Save time and money maintenance-free inhibitor.

• Environmentally friendly by using carboxylic acids in the additive package

Havoline XLI provides long-life protection against all forms of corrosion by the use of optimized and patented organic corrosion inhibitors. Excellent and lasting high temperature corrosion protection is provided for the aluminium heat transfer surfaces contained in modern engines. The inhibitor package of Havoline XLI offers excellent cavitation protection even without using nitrite or nitrite-based supplemental coolant additives (SCA’s).

Application

Havoline XLI provides long-life corrosion protection. Depending on the actual application the dosage may vary from 5 - 10 % but a minimum of 5 vol. % of Havoline XLI in water should be used. Havoline XLI may be used with confidence in engines manufactured from cast iron, aluminium or combinations of the two metals, and in cooling systems made of aluminium or copper alloys. The correct dosage of Havoline XLI is being checked with a refractometer. Please contact your local Arteco Area Sales Manager for more information.

Havoline XLI is particularly recommended for hi-tech engines like racing cars and heavy duty off-road equipment, where high temperature aluminium protection is important.

• In marine application the concentration of Havoline XLI should not be lower than 5 vol. %. At this dosage the recommended life-time is at least 32,000 hours. If Havoline XLI is replenished regularly to compensate for leakage, the cooling water can be considered as fill for life.

• Small marine engines sometimes require limited frost protection. This can be obtained by using the adequate dosage of Havoline Extended Life Antifreeze Coolant, based on ethylene glycol, supplemented with 5 % vol. Havoline XLI. For frost protections of -10 and -15°C, the required Havoline Extended Life Antifreeze Coolant dosages are respectively 22 and 29 vol. %.

• For off-road, truck and bus applications the recommended life time is 8,000 hours or 650,000 km, provided a concentration of 7.5 % vol. Havoline XLI is used.

• At 7.5 % vol., Havoline XLI will provide outstanding corrosion protection in stationary engines for at least 32,000 hours.

• Havoline XLI can also be used at 10 % vol. as a hot test liquid for new engine blocks. Newly manufactured engines are tested for duration of approximately 5 to 10 minutes , after which the fluid is drained and usually reused . If the engine blocks are not immediately built into vehicles , Havoline XLI will provide corrosion protection of the empty engine for up to two months.

• At 5 % vol. Havoline XLI performs as a flushing fluid to clean cooling systems that were filled with other inhibitor packages. In most cases it is required to flush the system twice. For a good result it is important that the engine has reached normal operating temperatures and all thermo-valves are opened.

• Havoline XLI can also be applied as an inhibitor package for central heating systems, hydraulic safety fluids and mining fluids.

The use of soft water is preferred for dilution. Though, lab testing has shown that acceptable corrosion results are still obtained with water of 20°dH, containing up to 500 ppm chlorides and 500 ppm sulfates. The water used for dilution should be free of zinc as presence of zinc will result in the formation of a precipitate.

Approvals by OEMs & national authorities

Havoline XLI has been approved by several engine manufactures and an up-to-date list with approvals is available separately . Even though some OEMs have not yet given a formal approval Havoline XLI is suitable for use in the applications as described on the application section.

Availability

Havoline XLI is available in bulk and various packages.
Please contact your  local Arteco Area Sales Manager on availability of packages, dilutions and colours.

In the range of organic acid technology Arteco can offer: 

• Havoline Extended Life Antifreeze Coolant (Havoline XLC) is the MEG-based coolant concentrate. 

• Havoline Extended Life Antifreeze Base (Havoline XLB) is a MEG-based superconcentrate. Havoline XLC is obtained by mixing 25 % wt of Havoline Extended Life Antifreeze Base with 75 % MEG.

• Havoline Extended Life Antifreeze Coolant – PG (Havoline XLC-PG) is based on MPG instead of MEG.

Separate information bulletins with more details are available for all these different products.

STORAGE REQUIREMENTS

The product should be protected from frost and direct sunlight during storage. The product should be stored at ambient temperatures and periods of exposure to temperatures above 35° should be minimized. Havoline Extended Life Corrosion Inhibitor can be stored for minimum 5 years in unopened containers without any effect on the product performance. Exposure to direct sunlight might cause discoloration, although the product itself and its properties remain stable. It is strongly recommended to use new containers and not recycled ones. These recipients should not contain zinc as this may influence the corrosion protection properties and stability of the product.
