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 provides a new robust rebuild process for EGR coolers to avoid the coolant flow being leaked and ensure the cooling effect. Utilizing 304 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 f rom ZHIFA ensures that the EGR cooler will continue to operate properly even when the flow of coolant has been inhibited. Its special features include: T304 stainless steel tube Brazing the tube with header Reduce engine emissions Improve fuel economy Prolonged engine life Custom design solutions Whether it's a personal vehicle or a work vehicle, f rom light duty to heavy duty engines, ZHIFA offers a wide range of EGR and Oil Cooling products.
