DefendAL™ Enviro Heavy Duty Extended Life Coolant/Antifreeze

DefendAL Enviro HD ELC is a virgin propylene glycol extended life coolant that contains a proprietary inhibitor system. In heavy-duty diesel applications it can provide a service life of 600,000 miles, with the addition of Extender at 300,000 miles. In automobiles this extended life Coolant/Antifreeze will provide a service life in excess of 5 years or 150,000 miles.

DefendAL Enviro HD ELC concentrate contains a inhibitor combination molybdate/nitrite to comply with ATA TMC RP 330 and ASTM D 6210 requirements for diesel coolants. It contains no added phosphates, silicates, nitrates or amines. It is a balanced combination of organic and inorganic additives and is compatible with both organic acid long life coolants and conventional inorganic coolants. In addition, our Extended Life Antifreeze will not cause turbidity, precipitation or inhibitor effectiveness reduction when mixed with other carboxylate-based coolants such as ChevronTexaco Extended Life Coolant or Dex-Cool nor with conventional coolants such as Prestone or Zerex. It is ideal for use in initial fills, coolant change-outs or top-offs.

DefendAL Enviro HD ELC meets ASTM D 3306 (automotive antifreeze), ASTM D 4985 (heavy duty antifreeze), ASTM D 6210 (fully formulated, pre-charged antifreeze) and TMC of ATA RP 330 performance requirements. It also meets or exceeds the following industry specifications as a concentrate or pre-diluted heavy-duty antifreeze/coolant for propylene glycol based coolants/antifreezes:

* Reserve Alkalinity (RA) is a term used to indicate the amount of alkaline inhibitors present in an antifreeze formulation. It is incorrect to relate a high RA value with high-quality antifreeze. Present state-of-the-art antifreeze formulations contain new inhibitor systems that give added protection to certain metals but do not raise the RA numbers.
