SCAs can be used to inhibit the cooling system with added protection against corrosion and other damage.

Cummins Filtration offers two liquid formulas, including:
  • DCA2
    • Standard Corrosion Protection Using Borate/Nitrite Based Inhibitor Package
  • DCA4
    • Superior Liner Pitting, Scale & Corrosion Protection Using Phosphate/Molybdate Based Inhibitor Package
SCAs can also be delivered to the cooling system by coolant filtration.
 
DESCRIPTION
LITERATURE
                       
DCA2 Supplemental Coolant Additive (SCA) provides superior engine protection in heavy duty diesel applications where glycol based coolants are used, as well as marine and railroad diesel applications where water is used as the coolant. DCA2 SCA contains Nitrite for liner pitting protection and Borate for acid protection.
  • Provides Diesel Line Pitting Protection
  • Provides Engine Metal Corrosion Protection
  • Mixes Easily with Standard Low Silicate Antifreeze
DCA4 Supplemental Coolant Additive (SCA) provides superior engine protection in heavy duty diesel applications where glycol based coolants are used, as well as marine and railroad diesel applications where water is used as the coolant. DCA4 is less toxic and, as a result, is preferred by those concerned about skin sensitivity and coolant spills or disposal. DCA4 contains Nitrite and Molybdate for liner pitting protection and phosphate for acid protection.
  • Provides Improved Cylinder Liner Pitting Protection
  • Provides Improved Aluminum and Solder Protection
  • Less Tendency to Form Gel in Cooling System
  • Improved Tolerance to SCA Under- or Over-charging
  • Phosphate Buffers Are Less Likely to Cause Water Pump Leakage
  • Less Toxic Than Borate/Nitrite Inhibitors
