Heat-recovery economizer EGR

Exhaust gas recirculation cooler The EGR Cooler, developed in close collaboration with our customers for medium and low speed engines, ensures that the recirculation exhaust-gas is mixed at the lowest possible temperature with the air for the combustion process. EGR Coolers are an essential element of EGR systems for the next engine generation which already now fulfills future emission guidelines according to IMO (International Maritime Organization), EPA (US Emission Protection Agency), EURO, etc. We have developed various cooler designs with regard to the different requirements of EGR Coolers at 2-stroke and 4-stroke engines. The patented design for 4-stroke engines high pressure EGR system enables cooling of exhaust gas, some of which are over 700 °C, down to 50 °C. All tests conducted with customers, at their facilities, have shown conformity with pollution results conducted at the prominent Research Centre for Internal-Combustion Engines and Thermodynamics at Rostock University in Germany. These tests have verified conformity of operational characteristics, especially pollution behaviour and transferred heat output. High-end software tools are implemented to predict the lifetime and reliability of the cooler under the extreme operation conditions.
