A new aftercooler core is available for the above engine applications that use low pressure gas fuel systems. The stainless steel alloy is able to resist the severe environment that is created by the following conditions:
Gaseous fuel with concentration levels of H2S that are greater than 3 Part Per Million (PPM)
High relative humidity conditions that are greater than 50 percentIn this environment, heavy corrosion may occur in an aftercooler core that is made of copper.Refer to the following Tables that list the replacement part numbers for the engine applications that are affected.
