TamerX has solved the problem of the EGR refrigerator. Most OEM chillers are failing due to cracks, which causes water and exhaust to mix or clog with exhaust reservoirs. We have developed a process that makes the cooler much more reliable and maintenance free. The TamerX design uses T304 stainless steel tubes to replace the turbulator design used in most OEM chillers. The stainless steel tube is welded TIG to precision laser cutting plates that are attached to the cooler housing. This will ensure that the cooler will work in the most difficult environments. This is essential for public transport vehicles such as school buses, ambulances and wrecker trucks.
