25 Ton Industrial FRP Counter Flow Cooling Tower - Injection Molding
The ZL-25T FRP counter flow cooling tower delivers 87.92 kW heat rejection at 25 refrigeration tons with 19.51 m3/h water flow rate. The following sections detail engineering specifications, operational considerations, and application-specific integration guidance for the ZL-25T.
The ZL-25T cooling tower's 19.51 m3/h flow rate is calibrated for injection molding mold cooling circuits at standard 5°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 optimal heat transfer. For a 200-ton injection molding machine with 4-cavity mold and 30 second cycle time, the ZL-25T provides sufficient cooling capacity for approximately 150 tons of injection machine clamping force per tower. The 32°C leaving water temperature from the ZL-25T enables consistent mold surface temperatures of 30-40°C (depending on chiller setpoint), which is critical for part quality and cycle time optimization. Closed-loop configuration prevents contamination between cooling tower water and hydraulic oil or mold release agents.
Consistent mold cooling water temperature is critical for injection molding cycle time and part quality. The ZL-25T's leaving water temperature of 32°C under design conditions provides predictable cooling performance regardless of ambient wet-bulb variations within +/- 2°C. For tighter cooling water temperature control (32.0°C +/- 0.5°C), the ZL-25T can be paired with a trim chiller to absorb wet-bulb variations. Cycle time consistency within +/- 1 second is typical with stable ZL-25T operation, compared to +/- 3-5 seconds with inadequate cooling water temperature control. The economic impact of cycle time consistency is significant: a 1-second cycle time reduction across 1250 molds per year yields approximately 3650000 kg additional part production.
For injection molding plants with multiple presses, the ZL-25T cooling tower can be sized for centralized cooling or distributed cooling configurations. Centralized cooling: multiple presses share a common cooling water loop served by the ZL-25T at 87.92 kW total capacity, enabling load balancing and peak shaving across the plant. Distributed cooling: each press has its own dedicated ZL-25T, providing redundancy and isolation but at higher total cost. For a 20-press plant with average 200-ton presses, centralized cooling requires 160 ZL-25T units, while distributed cooling requires one ZL-25T per 2-3 presses (10 units total). ZILLION provides cooling load calculation tools to optimize tower sizing for specific press configurations.
The ZL-25T's 32°C leaving water temperature is compatible with all standard mold materials including P20, H13, S7, and S50C tool steels. For tool steels with high hardness requirements (HRC 48-52), the cooling water temperature must remain stable to prevent mold thermal fatigue cracking. The ZL-25T's stable leaving water temperature prevents thermal cycling that can cause premature mold failure. For high-polish or chrome-plated mold surfaces, stable cooling water temperature preserves surface finish quality and extends mold life. For aluminum molds (lower temperature range), the ZL-25T can be paired with a chiller for 10-15°C mold surface temperatures used in thin-wall or optical part molding.
The ZL-25T cooling tower's 87.92 kW heat rejection capacity represents significant waste heat from injection molding operations that can be partially recovered for facility heating or water preheating. Typical injection molding energy consumption: 30-40% mold heating/cooling, 20-30% hydraulic system, 20-30% plastic melting, 10-20% auxiliary systems. The ZL-25T rejects all mold cooling heat to atmosphere, but 30-50% can be recovered through exhaust air heat exchangers or hot water extraction from the cooling water loop. For a 25-ton injection machine cluster, recovered heat of 26 kW can provide domestic hot water for 50-100 employees or supplement building heating in cold climates.
The ZL-25T cooling tower enables closed-loop cooling water circulation for injection molding operations, providing significant advantages over once-through cooling with city water. Closed-loop benefits: (1) Stable cooling water chemistry enables precise corrosion inhibitor dosing; (2) Consistent cooling water temperature independent of city water supply variations; (3) Water consumption reduced by 95% (only evaporation and drift losses); (4) Reduced water cost in metered city water markets; (5) Environmental compliance with industrial discharge regulations. The ZL-25T's 19.51 m3/h circulation rate supports closed-loop mold cooling for 200 tons of injection machine clamping force, with payback period of 2-3 years versus once-through cooling.

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.
