CDZ series marine low noise axial fan (hereinafter referred to as “fan”) is a new energy-saving, low noise marine unit our company designed with Shanghai research institute of the ship; it can be used to transport the air, the ocean air with salt mist. It’s applicable to cabins ventilation of the vessels and some other occasions.
CDZ-25~80 series marine low noise axial fan
“D”： low noise
“25~80”： impeller diameter
Fan is mainly composed of casing, impeller, motor support and marine motor.
Fan is mainly used for cabin ventilation, it also can be used to ensure unit normal operation.
Fan has the features of low noise, large air volume, big pressure head, high efficiency, and light weight. It has good corrosion resistance, shock resistance, the running is stable and safe, reversible operation can be selected according to users’ requirements.
· air flow：1500～27000m3/h
· total pressure：50～470Pa
· Power supply: standard configuration AC 3PH 380V/50Hz，AC 3PH 440V/60Hz，if need can choose：AC 3PH 415V/50Hz，AC 3PH 460V/60Hz，AC 3PH 480V/60Hz，AC 3PH 690V/60Hz.
· Casing: structure is barrel type; the main function is to gather gas and guide gas, improve fan efficiency, support motor and protect impeller
· Impeller: it is pressed by aluminum plate mould, wide shape blade; it has passed strict dynamic balance correction, over-speed test.
· Motor support: it is welded by common steel plate.
· Marine motor: It has good anti-moisture, anti-mould and anti-salt mist, stable operation, and low noise. The winding and metal parts of the marine motor all according to humid tropics motor requirement passed the special dipping and treatment. On the basement surface of the motor, there is a radiation rib which increases the cooling effect. Marine motor can add the space heater according to the requirement.
· Marine motor can choose Dezhou HL, Jiangsu Dazhong, Yuandong and other domestic brands, also can choose ABB, Siemens and other foreign brand
It was broadly used on the passenger vessel, cargo ship, warship and offshore platform.
