American Services cooling system installation in Chesterfield know that experts in the cooling system industry estimate that about 40 percent of down time is caused by cooling system maintenance problems. Researching and Understanding the common problems and implementing proven preventive maintenance practices will significantly reduce your operating cost. The four major problems associated with commercial cooling system breakdown and malfunctions are:
– Scale deposits
– Green-goo or drop-out
Corrosion what is it? Corrosion is the natural tendency of metals to revert back to their ore form; an example is cast iron oxides which will form reddish brown (commonly known as rust) deposits on engine services.
Similarly other metals form oxides. The color of the various corrosion events can vary from white to black depending on the specific oxide that has formed.
There are a variety of conditions in a cooling system environment which will affect the degree and rate at which metal surfaces corrode. Because these conditions are “generally present in all commercial cooling systems” this enables certified cooling system technicians such as those at American Services, to routinely perform preventative maintenance operations on many systems. These conditions include coolant Ph., which is simply the concentration of dissolved oxygen and carbon dioxide in a coolant, metal surface deposits, metal stress, coolant temperature, and acids formed in a combustion process of the fuel and the corrosion inhibitors present. To one degree or another of these conditions are present in “almost all commercial cooling systems,” once maintenance staff understand this, cooling system malfunctions like corrosion can be detected easily and early enough to prevent serious deterioration.
Under certain conditions all metals in the cooling system will corrode. Metallurgy science proves some metals are more sensitive than others, when metals corrode they weaken as a result, components fail. Aluminum is the metal most prone to corrosion in a cooling system environment, others include cast iron, solder, steel copper and brass to a somewhat a lesser degree will also corrode.
To reduce corrosion in your commercial cooling system a good corrosion inhibitor is a must.
Corrosion inhibitors should contain the following critical components
-pH buffer this will help maintain optimum coolant pH levels
-Silicate is the best known corrosion inhibitor for aluminum services
-TT and MBT Chemical inhibitors for protection of copper and brass
– Phosphate, Borate and Nitrate, the best corrosion inhibitor for iron, steel and aluminum.
These corrosive inhibitors are the simplest solution to corrosion problems.
