The Natural Draft Cooling Tower is an open, direct-contact system It works using a heat exchanger, allowing hot water from the system to be cooled through direct contact with fresh air. To increase the heat transfer surface area (and optimize the cooling process), hot water is sprayed from nozzles within the tower. The air flow is obtained by pressure difference obtained from its structure i.e. chimney effect. The offered Natural Draft Cooling Tower is very useful and made for industrial uses.
