Function of coolants

Bardahl offers a wide range of coolants: from a simple -38C to a biodegradable coolant. In addition, the range includes a range of radiator additives to solve or prevent cooling problems.

The main reasons why engine cooling systems are filled with complete coolants instead of normal tap water with antifreeze are:

• Permanent frost protection down to -38°C.

• Constant cooling due to better heat release properties.

• Thanks to the high reserve alkalinity, the metal parts in the system such as aluminum and copper alloys are constantly protected against electrolytic action of acids.

• Plastic and rubber parts are not affected.

• No clogging of the radiator due to rust and Sludge formation.

• Protection against rust and corrosion.

Different types of coolants are there?

Coolant can be found in many colors of red, blue, green and even transparent. The color says nothing about the quality but is only for recognition. Mixing the different types of coolants is not recommended. Mixing can cause problems such as loose oxidation layers that cause clogging, leaks of the water pump and/or head gasket and plastics and rubber can weaken or be affected with coolant loss as a result. Problems due to the use of different coolants interchangeably do not occur immediately but arise gradually.

Refill coolant

When coolant needs to be refilled, the advice is always to use the coolant prescribed by the manufacturer of the car. A minimal amount of coolant loss over time is acceptable, however, if you need to refill frequently, it is wise to add a radiator stop leak. NB Always do this with a cold engine.

Another possibility is, of course, to detect and fix the problem. If changing the coolant is necessary, always make sure that the prescribed coolant is used.

Finally, the freezing point says nothing about the condition of the additives in the coolant.

Coolant G11

Coolant -38 G11 is a blue coolant and retains its excellent properties for at least two years when used in a closed system. A semi-closed or open system should be refreshed annually for maximum security. The various packaging is adapted to both industrial and private use.

Coolant G12

Cooling Fluid –38°C G12 is nowadays commonplace to use as a heat transfer fluid in internal combustion engines. The heat from the internal combustion is brought to the radiator where the mixture is cooled by air. Cooling Fluid "38°C G12 provides maintenance-free protection against frost and corrosion throughout the life of the engine.

Antifreeze

Antifreeze is a nitrite/ amine-free refrigerant that protects the ferrous and non-ferrous metals (aluminum) used in the cooling systems against corrosion, overheating and freezing. Antifreeze consists of Mono Ethylene Glykol and a package of carefully selected additives to give the metals present in the cooling systems a high degree of protection against rusting and corrosion.

Antifreeze has the following properties:

• Miscibility with hard water (does not form flaky precipitation and associated blockages with hard water and/or normal tap water).

• Does not affect the usual hoses, gaskets and seals made of rubber and elastomers in the cooling system.

• Has excellent antifoam properties.

• When mixed with nitrite or amine-containing products, does not form the carcinogenic nitrosamine.

Concentrated Zitrec Drinking Water Antifreeze NSF HT1 Biodegradable

Zitrec Drinkwater Antifreeze NSF HT1 is - mixed with the right amount of water " a multifunctional refrigerant based on USP/EP mono-propylene glycol. This coolant prevents freezing of, among other things, the drinking water system, water tank, water pipes and toilet during winter storage and is effective down to -50 °C.

NSF is an independent institute that sets standards, issues certificates and deals with health risks and safety. The H1 approval means that these products are accepted and can be used as lubricants for use in the food industry, where occasional contact with food is possible.

Applications
This biodegradable antifreeze can be used for all water tanks of boats, caravans, mobile toilets etc. It prevents the formation of limescale deposits and does not affect rubbers, plastics and metals and is non-toxic.

Coolant Winter Storage

Coolant Winter Storage is a coolant that prevents freezing of all intercooling systems on board every ship during winter storage. This product is biodegradable, non-toxic and contains anti-rust ingredients, active down to -35°C. Protects metals and alloys in your plant against corrosion..

Applications
Can be used for all in- and outboard engines where there is a risk of running away into the environment (surface water)

Indy Racing Coolant

Bardahl Indy Racing Coolant protects all types of water-cooled competition engines. This coolant fights, stops and prevents the formation of foam, rust, corrosion and scale. Bardahl's special high-pressure components adhere to the metal surfaces of the cooling system and provide a protective film. The cleaning effect of the product will loosen and dissolve particles from the walls. Undissolved particles are kept in suspension until the cooling system is refreshed.

Radiator additieven

In addition to the widely usedRadiator Stop Leak and Radiator Fast Flush is also a special Anti Rust coolant additive. The main cause of poor cooling is the accumulation of sediment. As soon as rust and scale settle around the cylinders, so-called hot spots appear on the cylinder walls. Coal forms in these hot places, with the result that the cylinder walls are less and less able to transfer the heat to the water. Sounds from the water pump, especially squeaks and whines, indicate that the pump lacks lubrication. This means extraordinary wear and shortening of the life of the pump.

Bardahl Anti Rust & Waterpump protects all types of water-cooled engines. It fights, stops and prevents the formation of foam, rust, corrosion and scale. The light cleaning effect of the product will loosen and dissolve particles from the walls. Undissolved particles are kept in suspension until the cooling system is refreshed. In addition, Bardahl Lubricates Anti Rust & Waterpump also includes all moving parts of the water pump.
