Additive technology has advanced over the past few years, but even in developing technology, there are always some segments that seem to hold back. This tendency to hold back is because most of us tend to be cautious when it comes to taking care of our equipment. However, sometimes caution can be detrimental to our equipment as well.
Take the case of antifreeze/coolants. Our cooling systems in modern equipment has changed and developed over the years to handle the newer engines with their higher temperatures. Materials that are used in cooling systems are vastly different than they were even five years ago. The use of aluminum has increased and the types of brazing that are used have changed to provide smaller joints in the metal structures. All this is to make the modern cooling system better at its job of keeping our engines cool. To make these modern systems work properly, you need a modern coolant to work with it.
Still, caution has taken hold and some people still use conventional types of antifreeze/coolant that contain SCAs. (Check out our blog from last week for more info on the basics of SCAs.) Whether it is the conventional green coolants or the heavy-duty coolants with SCAs in them, these coolants are a product of the past.
SCA-based coolant technology was developed in the 1950s. It consists of solid additives that blanket the system to provide a protective layer on all the internal surfaces of the cooling system. This blanket was used because in the 1950s they did not have a better alternative. These SCA-based coolants worked well enough back then, but they are a poor substitute for what is needed in the modern cooling system.
Also, they have presented us with many issues that need to be resolved. Issues such as cavitation, pitting in the piston liners, and the wearing down of the water pump impellers are just some of these issues that continue to this day with SCA-based coolants.
So what’s the solution? Chevron ELC, XLC, and ELC Advanced coolants. These are NOAT and OAT technologies that use modern custom-developed additives to protect your cooling system while providing maximum cooling for the system. These coolants can go 750,000 miles without the need for any additives to be added. Also, Chevron ELC, XLC, and ELC Advanced contain no solid additives to blanket the system and restrict the transfer of heat. With these coolant technologies, you get the maximum cooling available in your modern cooling system.
So, why use 70-year-old coolant technology in your modern equipment? There’s no need when you can have the best protection available on the market! Call your Ottsen Oil expert for a run-down on Chevron ELC, XLC, and ELC Advanced coolants today.
