Coolants/Antifreeze 101

Jennie McRae - Tuesday, November 11, 2014

Engines are hot. Even engines with maximum efficiency will produce an excess amount of heat that could expand and seize parts of your engine. And since your business depends on the effectiveness of your equipment, it is imperative you use the right antifreeze to keep your engine healthy.

 

Antifreeze, or engine coolant, is used to lower the freezing point of a solvent. Typically, antifreeze is added to the water in your engine's cooling system--it causes that water to be cooled below the freezing point of pure water without freezing. And if you want to get really technical, ethylene glycol, methanol, ethanol, isopropyl alcohol, and propylene glycol are all used as the 'cooling agents' in popular brands of antifreeze. There will also most likely involve substances that inhibit corrosion in this mix, as well as antifoaming agents.

 

The two main types of antifreeze are standard and ELC (extended life coolants). Standard antifreeze will be either yellow or green in color, and is usually a mixture of ethylene glycol and water. ELC antifreeze will appear red in color and uses OAT (organic-acid technology) to provide superior protection. All antifreeze is offered in a 50/50 diluted mix or as a straight concentrate.

 

At COS, we offer a wide variety of antifreezes, such as:

 

ELC Antifreeze: ELC stands for Extended Life Coolant; these coolants appear red. Shell Rotella® ELC offers excellent heat transfer, corrosion inhibitor technology, and money-saving technology that will prolong the life of seals, hoses, and other cooling system components.

 

 Castrol HD Antifreeze with SCA: Castrol Heavy Duty Antifreeze with Supplemental Coolant Additive is designed to provide superior engine protection for heavy-duty cooling systems. This is a universal formula antifreeze, with advantages of low total dissolved solids, low silicate, and nitrite to provide superior wet sleeve liner cavitation protection.

 

 Shellzone Antifreeze: Shellzone is a superior quality, single phase, ethylene glycol based antifreeze. It is low silicate, all-purpose, and designed for use in both automotive and heavy duty diesel engines (with the use of SCAs).
