1. The material of American Weil-McLain boiler is excellent pearlite with low sulfur and low phosphorus, the elastic modulus is large and tenacity is strong. It has strong anti-corrosion feature because of the unique intergranular structure and the life long of the cast iron boiler is 40 years. The long life is one of the biggest features of cast iron boiler.2. Tininess is another big feature of cast iron boiler: The overall installation size of cast iron boiler is half of the ordinary boiler, which decreases the investment cost of boiler room greatly. And it can be assembled and used in narrow spaces that are not easy to access.3. Manufacturing and installation period is short: The body of cast iron boiler is assembled by many slices, so the manufacturing period is short. The installation of cast iron boiler is convenient and there is no mass welding and complex special equipment, which shortens the installation period of boiler.4. Security feature is high: the cast iron boiler is assembled by slices and the unique structure and material make it nonexplosive products.5. Thermal efficiency is high: thermal efficiency actually measured is up to more than 90%. The heating surface in the smoke flow place is full of heat collection cone, it strengthens the disturbance of smoke at the same time of increasing the heating surface so that the heat conductivity coefficient is increased greatly, which guarantees the high efficiency. 6. Enough output and small pollution: The outputs of cast iron boiler are obtained through actual inspection. The assorted burners in our company are all products with the international brands, such as RIELLO, Oilin, Nu-way, etc. The technology is advanced and the burning efficacy can be up to 99.9%. It not also guarantees the fully burning of fuel, but also declines the emission of pollutant, which is accordance with the requirements of the state A-class regions and the busy area in downtown area. 7. The inspection and regulation functions are completed: It has automatic purging procedure of the furnace, gas leakage alarm system, chain protection procedure of security operation, flame-out protection procedure, automatic protection when the gas pressure higher or lower than the set value and protection of default of the motor overload of the burner. 8. Automatic control level is high and security performance is high: Control the pressure, temperature, over pressure, over temperature and water depletion of the boiler and can conduct interlock protection. At the same time, it is equipped with burner of the excellent brand and complete controlling system, which can realize automatic operation of the boiler and unattended operation.9. It can realize combination control of many machines. Many American Weil-McLain boilers can be used in large scale constructions. We can trace the change of thermal load accurately and decrease the operation cost maximally. And boilers can be standby for each other, which can reduce the investment.
