EGR(exhaust gas recirculation) cooler is used to cool off the exhaust gases before they are recirculated back into the combustion process. By cooling the gas, it helps to reduce engine emissions and improve fuel economy for commercial-duty diesel applications and provide superior heat rejection with less soot and hydrocarbon buildup. ZHIFA provide a new robust rebuild process for EGR coolers to avoid the coolant flow being inhibited and ensure the cooling effect. Utilizing T304 stainless steel tube, ZHIFA-EGR eliminates the turbulator design used in most OEM EGR coolers. Then, this new stainless steel tube is brazing welded to precise cut plates attached to the cooler housing. This new design from ZHIFA ensures that the EGR cooler will continue to operate properly even when the flow of coolant has been inhibited.
