Closed-Circuit Cooling Tower
The cooling tower features a compact structure and high heat dissipation efficiency. It is typically installed outdoors or on rooftops of liquid-cooled data center facilities. With a rated heat dissipation capacity of 3000 kW @ ΔT=3℃ (under standard conditions: wet-bulb temperature 31℃, tower outlet water temperature 34℃), it can provide primary cooling water at temperatures ranging from 25°C to 45°C. Depending on project requirements, the cooling tower can be configured with 2N or N+1 redundancy. Cooling towers are commonly used in areas where water sources are readily available. They utilize water and air as cooling media to exchange heat with the overheated medium inside the coils. Heat released during the cooling process of the internal medium is dissipated through partial evaporation of water outside the tubes.
Product Features:
◆ Closed-loop cooling tower with a cooling capacity range of 30–3000 kW.
◆ Specialized cooling tower motors with high efficiency, high protection rating, and insulation class.
◆ Fan speed adjustable via VFD, allowing airflow to adapt dynamically to load conditions.
◆ SUS304 stainless steel heat exchange coils offering high corrosion resistance and system reliability.
◆ Outlet fluid temperature control accuracy within ±2°C.
◆ Flanged water supply and return connections for easy installation and maintenance.
◆ Compact design with high heat dissipation efficiency.
