The BTC series closed cooling tower utilises water and air as cooling media, exchanging heat with the high-temperature working fluid within the coil. The high-temperature working fluid releases heat and transforms into ambient-temperature fluid. Internally equipped with a water distribution system, cooling coils, and water separators, externally fitted with a circulating water pump and electronic water treatment, with an axial fan mounted at the top. During operation, the axial fan creates a negative pressure environment inside. Cooling water is distributed uniformly across the coil surface via the water distribution system, enabling heat exchange between the high-temperature working fluid and the water and air surrounding the coils. This enhances the cooling effect significantly. After absorbing heat from the coil walls, the cooling water temperature rises sharply. Part of the cooling water vaporises into steam, while the non-vaporised portion returns to the sump tank. The sump pump then recirculates this water back into the water distribution system for continued operation. Water lost to the atmosphere is replenished promptly via a float valve in the sump tank, which regulates the water level.
