Antifreeze helps prevent liquid from freezing in sub-zero temperatures, and preventing boil-outs above the designated boiling point of the same so that it doesn’t evaporate.
A study confirms three-fifth of all engine problems are coolant-related. For an engine to operate optimally, only one-third of generated heat/ energy is required and the rest is released or transferred. If this transfer does not take place, it would lead to overheating of engine equipment, causing breakdown and/ or failure. Overheating adversely affects the engine's efficiency directly, affecting performance, fuel economy, maintenance, and longevity of vital engine components. Using recommended coolant ensures that the engine runs at an optimum temperature without any heat-related hassles.
What is coolant to begin with?
Coolant,
derived from antifreeze chemicals are commercial grade antifreeze chemicals
used in automobiles, DG sets, heavy-duty systems, etc., protecting the engine
from getting disintegrated/ damaged at higher temperatures by transferring the
excess heat formed.
Generally,
coolants used in engines are homogeneous mixture of glycol and water, reason
being their flexible thermal properties like high boiling point, low freezing
point, stable over a wide range of temperature but …
… Is coolant enough?
Glycol
oxidizes at high temperatures into organic acids: glycolic, glyoxalic, formic,
carbonic and oxalic. These are highly corrosive and can be corrosive to the
system metal causing problems like pitting, pinhole and stress cracking
corrosion. Even the resulting contaminants present in glycol adding more to its
rate, degrading the total working system.
The main problems with this undesirable acidity are:
·
Affects
metallic pipelines, which leads to failure of temperature balance owing to heat
loss
·
Pitting
causes irregular holes, gradually leading to leakage of coolant into the combustion
chamber
·
Scale
depositions disrupt the heat transfer efficiency of the coolant
To tackle these problems, coolant
additives such as corrosion inhibitor chemicals were synthesized.
Coolant corrosion inhibitor are chemical additives that when added to coolant to protect the internal surfaces from corrosion related adverse effects. These inhibitors made with components of the finest grade not only ensures efficient reduction in mineral scale and sludge deposits but also provides efficient protection to metallic components from corrosion with its unique features like anti-corrosion and system life enhancement.
Coolant – Inhibitor Technology
· IAT based: Inorganic Salt additives based coolant
· OAT based: Organic Acid Technology based coolant
· HOAT based: Hybrid organic acid technology (HOAT) is combination of IAT and OAT technologies
Compatible
with heavy duty coolant, comprising of glycol, water and corrosion inhibitors
that control irregular pitting, scaling, etc. Heat produced by the engine is
absorbed by the coolant which helps in maintaining regulated temperature in the
system, transferring excess heat to the appropriate media and the incorporated
inhibiting property makes the metallic surface inert against all types of
oxidizing reaction of organic acids, ensuring corrosion free heat transfer
system.
Coolant
Corrosion Inhibitor provides anti-freeze properties, boil over protection, and
component protection and meets all the requirements as per industry standards. These
are formulated by making use of premium grade chemicals with sophisticated
methodologies for anti-corrosion, anti-scaling, and anti- fouling properties.
