Granville Sub-Zero Green is ethylene glycol based formulated for optimum performance in heavy duty diesel engine applications but equally suitable for light duty use.
It employs established inhibitor technology and is phosphate and amine free. BTC classification type 3EN.
The 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 erosioncorrosion to occur.
The product 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 prevent the formation of scale that can result from the use of hard water.
