Ingersoll Rand 49086812 Heat Exchanger Assembly

The 49086812 heat exchanger functions as a water-cooled oil cooler for Ingersoll Rand M355 series rotary screw air compressors. It utilizes a brazed plate construction to transfer heat from compressor lubricating oil to a cooling water circuit, maintaining optimal oil viscosity and compressor operating temperature. Constructed with stainless steel plates and carbon steel connections (CS+SUS304), the unit is designed for high-pressure industrial environments. It serves as a direct replacement for OEM part numbers 49086812, 49186919, and 24746927. The component is critical for preventing overheating and ensuring continuous duty cycle reliability in manufacturing and process air systems.
