Dober Chemical Corp. TR81167

Dober Chemical Corp. TR81167 is a borate/nitrite cooling water treatment, provides superior corrosion and scale protection for today’s modern locomotive and marine diesel engine. Dober TR81167 contains a complete corrosion inhibitor system that protects not only the yellow metals, cast iron and steel in your system, but aluminum and solder as well. This feature lowers maintenance down time and part replacement costs. The effective deposit inhibitor in Dober TR81167 works to prevent scale should your make-up water contain some hardness. Prevention of scale results in improved oil cooler and engine block heat transfer, better flow rates, cooler water temperatures, and reduced maintenance costs. Plugged radiator passages from scale that has broken loose cease to be a problem.

Applications & Uses

Application Area
Usage
  • TR81167 can be added directly, as received, to your engine cooling system. Because the bag is water soluble, there is no need for maintenance workers to touch the chemical.
  • The normal recommended treatment level of Dober TR81167 is 0.64 dry ounces per gallon of cooling system capacity. This dosage gives a conductivity of approximately 3900µS/cm above that of the makeup water.
  • To ensure adequate inhibitor levels, sodium nitrite levels should be maintained between 1500 and 2250 mg/L as NaNO2.
  • Dosage (Dry) - 0.64oz/gallon
