Granville Zerocol 48 is ethylene glycol based and formulated for optimum performance in heavy duty diesel engine applications, but is equally suitable for light duty use.
The product employs established inhibitor technology and is phosphate and amine free. Inhibitors include organic acids in combination with borate, silicate and nitrite which are well known for their ability to provide excellent protection in heavy duty applications, particularly when there is potential for cavitation erosion-corrosion to occur.
Granville Zerocol 48 uses sophisticated silicate stabilisation technology to eliminate the potential for formation of silicate gel, often observed with inferior products, whilst other additives ensure good compatibility with hard water and prevents the formation of scale that can result from the use of hard water.
BTC classification type 3EN.
