Locomotive Coolant Chemistry

Dober products have been qualified with both GE Transportation Systems (GETS Maintenance Instruction MI-09500E) and Greenbriar Equity LLC and Berkshire Partners LLC Electro-Motive Division (meets the requirements of EMD Maintenance Instruction 1748) to provide corrosion and scaling protection in diesel engine transportation applications. Additionally, Dober supplies most locomotive factory fill corrosion inhibitor products in North America. Our technical experts work directly with the manufacturers' design and support staffs to create appropriate cooling system solutions that maintain diesel engine longevity.

Dober's railroad products are high performance formulations that suppress corrosion in all commonly used metals, while inhibiting scale and deposit formation. They are the cornerstone of efficient maintenance practices that enhance the useful life of railroad diesel engines, cooling systems and associated equipment.

Dober also brings this experience and expertise to the aftermarket where we supply these same proven products and solutions to class1 carriers and local short line service providers.

Product	Description
