Cannon evaporators consist of a high speed blower system, water supply system, atomising nozzle system, chassis system, etc. An atomising nozzle system to break the water pumped into pieces for a second atomisation through a high speed blower system for quick evaporation. Height of the equipment is adjustable through the chassis system, allowing it to fit in different sites. Includes an electronic control system to start or stop equipment. The weather monitor system allows observing wind forces, wind direction, temperature, humidity to control the water-drop drifting limits and the operational costs of the system, making sure a high-effective evaporation is achieved.
