| Much confusion in the heavy duty antifreeze
market surrounds the addition of supplemental coolant additives (SCAs).
Heavy duty antifreezes require SCAs to provide cavitation
protection. Because SCAs deplete during use, antifreezes require
SCA additions many times during the life of the antifreeze. These
multiple additions cause a large amount of variance in the level
of SCAs found in most cooling systems. This situation is worsened
by the fact that most heavy duty cooling systems leak. Leaking
systems require "top-off" with fresh antifreeze for
proper maintenance. Topping-off with non-SCA charged coolant only
adds to the variability of an already variable system. In order to
help alleviate this problem Old World Industries has introduced Fleet
Chargeâ and Fleet Charge/PGâ
fully formulated antifreezes. This paper will discuss how
using Fleet Charge antifreeze can greatly reduce the
variability associated with heavy duty coolants. When using a conventional antifreeze to initially fill a heavy duty cooling system, addition of a separate SCA provides protection against cavitation. At this point it is fairly easy to determine the level of SCA to add. You know there is no SCA already in the coolant and you know how much coolant you added. From this point forward the situation becomes more complicated. As the vehicle operates, the SCA depletes. With continuing depletion it becomes necessary to add additional SCA. Additionally, most systems leak. In order to maintain the proper freeze protection and coolant level it is necessary to add additional antifreeze. Addition of non-SCA containing antifreeze to make up the volume of antifreeze that has leaked out further reduces the SCA in the antifreeze. Due to these variables the exact time at which to add additional SCA, and the amount of SCA to add, becomes a guessing game. SCA manufacturers have begun to help with some of these problems. One way to reduce variability is to use coolant filters equipped with multiple doses of SCA. These filters utilize a sacrificial membrane to add SCA to the coolant as needed. The filters sense the SCA depletion and add the correct SCA dosage at the correct time. Although these filters address SCA depletion, they do not solve the problems associated with initial fill and top-off. For these reasons Old World Industries has introduced Fleet Charge Antifreeze. Fleet Charge antifreeze is a universal formula, low silicate antifreeze that has been pre-charged with a high quality SCA. When initial filling with Fleet Charge antifreeze there is no need to add additional SCA. When topping off a leaking system with Fleet Charge antifreeze, there is no need to compensate for SCA dilution. Use of Fleet Charge antifreeze with a high quality SCA filter greatly reduces the variability often found in heavy duty cooling systems. Reduced variability is not the only advantage in
using Fleet Charge antifreeze. Fleet Charge
antifreeze incorporates state of the art corrosion and cavitation
inhibitors along with anti-scale additives. For these reasons Fleet
Charge antifreeze does not require dilution with DI water
(although we always recommend using the highest quality water that
is available). Fleet Charge antifreeze is a phosphate free
universal formulation that meets all heavy duty and automobile
conventional antifreeze specifications. Therefore Fleet Charge
antifreeze is also well suited for use in automobiles and light
service trucks. This makes it possible for operators of mixed
fleets to stock only one antifreeze. Fleet Charge
antifreeze stands out from its competitors due to its unsurpassed
performance, but it also stands out due to its unique
"pink" color.
