From hvac epc contractor to other buyer perspectives, the ZL-10T platform reports across ten sustainability contexts:
Quick Specs: ZL-CT40 industrial round cooling tower with 40-ton cooling capacity, FRP material, counter-flow design, 1.5kW fan, CE certified. Best for industrial chiller systems and mid-scale manufacturing. The water cooling tower is a device used for cooling circulating water. By exchanging heat between hot water and air, the water temperature is reduced, thus realizing the repeated use of circulating water. Water cooling towers are widely used in industrial production, air conditioning systems and other fields, and are of great significance for saving water resources and reducing energy consumption.
Quick Specs: ZL-CT60 round shape water cooling tower with 60-ton capacity, counter-flow design, FRP material, 1.5kW fan, CE certified. Best for industrial chiller systems and large-scale cooling. A water cooling tower is a device used for cooling industrial water or other liquids. Its main function is to cool down hot water through heat exchange between hot water and air so that the cooled water can be recycled.
Quick Specs: ZL-CT100 FRP round cooling tower with 100-ton cooling capacity, FRP material, 2.2kW fan, CE certified. Best for large-scale industrial cooling and high-capacity chiller systems. The counterflow cooling tower is a common type of cooling tower. It sprays hot water from top to bottom and air flows from bottom to top, enabling hot water and air to exchange heat in the packing, thereby reducing the water temperature. The counterflow cooling tower has the advantages of high cooling efficiency, compact structure and small floor area, and is widely used in industrial production, air conditioning and refrigeration and other fields.
Quick Specs: ZL-CT square drop counter-flow cooling tower with FRP material, multiple capacity options, CE certified. Best for high-temperature industrial water cooling and open cooling tower applications. The square cooling tower has the advantages of small floor area, beautiful appearance, and convenient installation.

Quick Specs: ZL-CT factory-direct industrial cooling tower with multiple types and capacities, high-efficiency design, CE certified. Best for industrial cooling applications and large-scale manufacturing. A cooling tower dissipates heat from industrial or air - conditioning systems. Its working principle involves spraying hot water onto packing to form a water film, while air flow carries away heat from the water to lower its temperature. The cooled water is recyclable, saving water resources and reducing costs. There are various types, such as open and closed cooling towers. Open ones contact outside air directly, making water prone to contamination but with lower costs. Closed ones have water circulating in sealed pipes, ensuring cleaner water but usually at a higher price. Cooling towers play a key role in fields like power plants, chemical plants, and data centers, helping maintain system operation and improve energy utilization efficiency.
