The inhibitors in KOOL-GUARD H-OAT -38 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 where there is potential for cavitation erosion-corrosion to occur.

KOOL-GUARD H-OAT -38 uses sophisticated silicate stabilisation technology to eliminate the potential for the 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.
