Water aluminum radiators with pleasing shape,durable quality,reasonable price and safe capability. And our radiators are die casted by die casting machines in one step. Features: 1) The adoption of European-style aluminum fins in radiator complies with the long-winged design in fluid mechanics 2) The special aluminum alloy has good thermal conductivity and is capable of producing heat under max power output 3) Process of degreasing and oxidation of radiator surface prior to spray painting, which ensures that the paint will not fall off 4) The water chamber is twice treated against corrosion to ensure it is corrosion-proof while operating in pH<12 water 5) The complete test method, including 1.8MPa hydro test and alternating cold and heat test under the pressure for the individual fin and for the fin group is a good guarantee of the safety and reliability of products Specifications: Model NO.
