Our shell & tube EGR coolers adopt optimized tube bundle layout to achieve stable heat transfer efficiency. The gas-inside-tube configuration provides superior resistance against soot fouling and allows convenient periodic flushing. Manufactured from 316L stainless steel to withstand acidic exhaust condensate. We add optional internal turbulators to raise overall heat transfer coefficient, maintaining reliable EGR gas cooling performance for heavy-duty Cummins, MTU and Perkins diesel generators over long operating cycles.
