CGDL Series Marine High Efficiency Low Noise Centrifugal Fans
General
CGDL series marine high-efficiency low-noise centrifugal fans (hereinafter referred to as the fans) are new energy-saving, low-noise marine products. The fans are specially designed with a special design of impeller, inlet and outlet, so that the fan has high efficiency (η > 80%), low noise, overload, stable operation and can meet marine conditions. It is suitable for cabin ventilation, air conditioning and also applicable to other similar places.
Features
The fans are specially designed with aerofoil blade and inlet. The dimension and line of the casing are designed specially according to characteristic of speed. The impeller are processed specially so that air flows perfectly and the fan have the advantages of high efficiency and low noise. When power gets to large flow, it gets down steadily. Therefore the motor can’t be damaged due to overload.
During the course of design & manufacture, we had thought fully of the marine special conditions. The impellers are made of aluminum alloy with strict dynamic balance & over speed test. Therefore, the fans also have the features of anti corrosion, Resistance swing, shock resistance and vibration resistance, stable turning, safety & reliability etc.
Structure
The fans are horizontal with motor direct coupling. However it can also be constructed into a vertical type.
The impellers are aluminum alloy and blades are aerofoil. They are adjusted strictly by dynamic balance, thus have good aerodynamic performance. The casing and inlet are made by common galvanized steel sheet.
The outlet directions of No. 40~80 of the fans are 0°~225° and change by 22.5°.
