Currently on the market, mainly by iron radiator, aluminum radiator, steel radiator three cast iron radiator cast iron radiator depress its Order of the crude bulky shape, high energy consumption and production good many can not overcome the disadvantage, the market will gradually be phased out. 2, steel radiator, steel radiator style points mainly both plate and pillar. Especially steel column radiator with steel column Workers radiator, won the favorite of many consumers with its rich colors and beautiful appearance. To buy steel radiators to understand whether the district heating system to match, using open heating system heating consumers to carefully selected steel radiator, steel radiator case of oxygen oxidation corrosion prone to open the boiler and The oxygen content in the water, there are strict requirements, required full of water and maintenance of the primary system after a heating service, if maintenance is not good, the radiator will soon fill corrosion resulting in the final leaky radiator. 3, aluminum radiator aluminum radiator pressure cast aluminum and tensile aluminum alloy welding two. The advantages are mainly: ① aluminum heat better energy saving features are very obvious, in the same room, with the same specifications as the radiator, cast aluminum piece less than steel. ② resistance to oxidation of the aluminum corrosion, do not add any additives, the principle is that the aluminum memo to generate a layer of oxide film event of the oxygen in the air, and this layer is both tough and dense prevent further corrosion body material. Select aluminum radiator, the best choice for high-pressure cast aluminum module combined radiator. The radiator is a the overall die cast, so no weld leakage problem. And its biggest advantage is that the product is free from the restrictions of the district heating system, can not even open boiler system the oxygen corrosion due to the use of modular design, after heating a quarter, if the indoor temperature is not enough, but also hold one or two in the second year, plus to meet their own needs, rather like steel radiator needs to the entire group of Heating replaced. Aluminum radiator water quality requirements with steel (steel material requirement the system water PH value is less than 7, and aluminum materials require water PH value is greater than 7, resulting in contradictions) should avoid aluminum The radiator is installed mixed with other materials.
