What is Diesel Exhaust Fluid (DEF) ?
Diesel Exhaust Fluid is the proportion of 33.5% Aqueous Urea in deionised water. Diesel Exhaust Fluid is not fuel or fuel additive.
Where does DEF require?
DEF is required majority of heavy duty diesel vehicles. Diesel vehicles should be Euro IV & Vemissions limits and SCR equipped.
What is selective catalytic Reduction (SCR)?
SCR is a technology that uses a Urea based diesel exhaust fluid known as DEF and a catalytic converter to significantly reduce oxides of nitrogen (NOx) emissions.
What are the benefits of using Autofiled Safeguard (DEF)?
Diesel Exhaust Fluid (DEF) is one of the important solution involved in the SCR after treatment technology. Use of DEF to convert NOx into harmless nitrogen and water vapor. It is stable, colourless, odorless and meets acceptable international standards for purity and composition.
Autofield Safeguard (DEF)
DEF designed specifically for modern integral Selective Catalytic Reduction (SCR) NOx reduction systems. The finished formulation is further to ensure maximum protection for internal SCR System components.
Selflife of Autofield Safeguard DEF
As per ISO 22241-3 standard, the selflife of DEF at constant temperatures up to 30°C is minimum 12 months at constant temperatures up to 35°C the self life is reduced to a minimum of 6 months. It is recommended that DEF should be stored out of direct sunlight and below 35°C. Where higher ambient temperatures are experienced, tank should be insulated or stored in shaded area. Minimum temperature is -11°C
Why does the cooling system needs the quality based radiator coolant, not water/inferior coolant ?
The quality based radiator coolants can protect the cooling system from high boiling in summer and freezing in winter. Inferior coolant and water doesn't have these functions.
Can Autofield coolant be mixed with other brand radiator coolants ?
It is not recommended. if you mix with other brand radiator coolants, it will affect the coolant performance.
What is the difference between the Green coolant and Red one ?
The function of the Green coolant and the Red one Completely same.
