ZL-50T 50 Ton Industrial FRP Counter Flow Cooling Tower - Injection Molding
The ZL-50T FRP counter flow cooling tower delivers 175.81 kW heat rejection at 50 refrigeration tons with 39.2 m3/h water flow rate. The following sections detail engineering specifications, operational considerations, and application-specific integration guidance for the ZL-50T.
The ZL-50T cooling tower's 39.2 m3/h flow rate is calibrated for high-tonnage injection molding mold cooling circuits at standard 5 deg C range. This flow rate supports mold cooling channels with typical 5-15 mm diameter passages operating at 1-3 m/s water velocity. For 50-ton and larger injection molding machines, the ZL-50T provides sufficient cooling capacity. The 32 deg C leaving water temperature from the ZL-50T enables consistent mold surface temperatures of 30-40 deg C.
Consistent mold cooling water temperature is critical for injection molding cycle time and part quality at industrial scale. The ZL-50T's leaving water temperature of 32 deg C under design conditions provides predictable cooling performance regardless of ambient wet-bulb variations within plus or minus 2 deg C. For tighter cooling water temperature control (32.0 deg C plus or minus 0.5 deg C), the ZL-50T can be paired with a trim chiller. Cycle time consistency within plus or minus 1 second is typical with stable ZL-50T operation.
For injection molding plants with multiple high-tonnage presses, the ZL-50T cooling tower enables centralized cooling configurations. For a 20-press plant with average 400-ton presses, centralized cooling requires 160 ZL-50T units. Each ZL-50T provides 175.81 kW heat rejection at design conditions. ZILLION provides cooling load calculation tools to optimize tower sizing for specific press configurations.
The ZL-50T's 32 deg C leaving water temperature is compatible with all standard mold materials including P20, H13, S7, and S50C tool steels. For high-tonnage molds with high hardness requirements (HRC 48-52), the cooling water temperature must remain stable to prevent mold thermal fatigue cracking. The ZL-50T's stable leaving water temperature prevents thermal cycling that can cause premature mold failure.
The ZL-50T cooling tower's 175.81 kW heat rejection capacity represents significant waste heat from high-tonnage injection molding operations. Typical injection molding energy consumption: 30-40 percent mold heating/cooling. The ZL-50T rejects all mold cooling heat to atmosphere, but 30-50 percent can be recovered through exhaust air heat exchangers. For a 50-ton injection machine cluster, recovered heat of 52 kW can supplement building heating in cold climates.
The ZL-50T cooling tower enables closed-loop cooling water circulation for high-tonnage injection molding operations. Closed-loop benefits: stable cooling water chemistry, consistent temperature independent of city water variations, water consumption reduced by 95 percent, reduced water cost, environmental compliance. The ZL-50T's 39.2 m3/h circulation rate supports closed-loop mold cooling for 400 tons of injection machine clamping force, with payback period of 2-3 years versus once-through cooling.
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.

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.

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. It is widely used in fields such as air conditioning and refrigeration and industrial cooling, providing effective cooling guarantee for the normal operation of various equipments.
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.
