1.Air dryer gas liquid separator uses a three-stage separation: direct collision separation high speed centrifugalseparation stainless steel wire mesh demister separator. 2.Domestic evaporator welding is basically using copper pipe welding, distribution pipe and collecting pipewelding contact surface is small, poor welding strength and easily lead to false welding. We use the domesticlatest pull whole process, a great increase in the copper welding surface. It resolves the evaporator leakageproblem in present market basically. 3.The new designed air dryer uses stainless steel triple plate or alloy aluminum plate to replace the traditionalcarbon steel material, avoid the secondary pollution problems from carbon steel corrosion and reduce the risk ofleakage. Greatly enhance the product performance, reduce the size of equipment, but also bring visual aestheticsto the customer.
