Deskripsi
Cooling Tower Special Reducer
Series : NGW-LF
Brand : Hebei Heavy Machinery Equipment Co., Ltd.
NGW-LF series cooling tower reducers are specially designed for cooling towers. They use planetary gear transmission and are matched with motors with an IP55 protection grade. They use a load impeller for cooling and are characterized by high efficiency and energy saving, good sealing, low noise, stable operation, and ease of use.
They are widely used in the steel, refrigeration, chemical, petroleum and other industries.
