20 Ton Industrial FRP Counter Flow Cooling Tower - Injection Molding
The ZL-20T 16 m³/h flow at 5°C range covers typical injection mold cooling circuits:
Mold cooling water flow: Typical flow rate 4-8 L/min per mold cavity. ZL-20T supports 33-67 cavity molds (or 2-4 large multi-cavity molds) at design flow.
Temperature stability: Mold cooling water at 25-30°C maintained within ±1°C by ZL-20T leaving water temperature control. Critical for cycle time consistency and part quality.
Cooling water quality: Filtered to 50 µm to prevent nozzle clogging in mold cooling channels. ZL-20T integrated strainer removes larger particulates.
Heat load per shot: 200-ton press at 200g shot weight dissipates 15-25 kW during injection cooling. ZL-20T supports 3-4 such presses at peak load.
Annual operating cost: ZL-20T USD 482 fan energy + USD 200 pumping + USD 150 water treatment = USD 832/year per cooling tower serving injection molding line.
Consistent mold cooling water temperature directly affects injection molding cycle time and part quality:
Cycle time impact: ±2°C cooling water variation causes ±3-5% cycle time variation. Maintaining 32°C ±1°C supports tight production scheduling.
Part quality: Cooling water temperature drift causes warping, sink marks, and inconsistent shrinkage. ZL-20T 5°C approach stability minimizes these defects.
Process capability: For Cpk targets 1.33+, cooling water temperature variation must stay below ±1°C. ZL-20T approach stability supports statistical process control requirements.
Production rate: 5% cycle time improvement from stable cooling = approximately USD 50,000/year additional production value for typical mid-size molding facility.
Scrap reduction: Stable cooling reduces part rejection by 10-15%, supporting lean manufacturing goals.
The ZL-20T 70 kW capacity covers typical multi-press plant configurations:
200-ton press + ZL-20T: Single 200-ton press at 30 kW peak heat load. ZL-20T 70 kW capacity supports 2 presses at average load with 100% overhead for peak demand.
350-ton press + ZL-20T: Single 350-ton press at 50 kW peak. ZL-20T covers 1 press with moderate peak load margin.
Multi-press plant (4 presses, 200-300 ton): Total peak load 100-150 kW. 2-3 ZL-20T units in parallel support full plant cooling with N+1 redundancy.
Injection molding facility planning: ZL-20T units scale with production capacity. Standard practice: 1 ZL-20T per 2-3 presses depending on shot weight and cycle time.
Centralized vs distributed cooling: Single ZL-20T serves 2-3 presses at point of use (distributed), or multiple ZL-20T in central plant serve larger facility (centralized). Both configurations supported.
The ZL-20T cooling water chemistry compatible with common mold materials:
P20 tool steel: Standard injection mold material. ZL-20T cooling water at 25-30°C supports P20 with corrosion inhibitor treatment.
H13 hot work steel: High-temperature mold material for engineering plastics. Compatible with ZL-20T standard water treatment regime.
S136 stainless: Corrosion-resistant mold material for PVC and corrosive plastics. ZL-20T SS316L upgrade recommended for these applications.
Beryllium copper mold inserts: High thermal conductivity inserts. Compatible with ZL-20T standard water chemistry.
Cooling channel corrosion: Standard ZL-20T water treatment prevents corrosion in steel mold cooling channels. Annual mold inspection recommended.
For high-end mold applications, ZL-20T SS316L upgrade minimizes cooling system corrosion risk.
The ZL-20T 70 kW heat rejection represents significant thermal energy that can be recovered:
Heat recovery options: ZL-20T heated water (35-40°C leaving water at peak load) can pre-heat facility domestic hot water or feed absorption chillers for combined cooling and heating.
Energy savings: 30% of mold cooling waste heat recoverable at 50% efficiency = 10 kW thermal energy = USD 5,000/year value at commercial gas rates.
Carbon impact: Heat recovery offsets gas consumption, reducing facility Scope 1 emissions by 15 tonnes CO2/year per ZL-20T.
Implementation cost: Heat exchanger piping USD 500-1,000 per ZL-20T installation. Payback 1-2 years for facilities with year-round heating demand.
For plastic processing facilities pursuing circular economy or net-zero emissions, ZL-20T heat recovery is a viable component.
The ZL-20T supports both closed-loop and once-through cooling configurations for injection molding:
Closed-loop (recommended): ZL-20T cools tower water, which circulates through mold cooling circuits. Closed system minimizes water consumption and treatment requirements.
Once-through (legacy): Cooling water drawn from facility source, used once, and discharged. Higher water consumption but no cooling tower requirement.
Hybrid configuration: ZL-20T supplements once-through cooling during peak summer loads. Reduces water consumption by 40% compared to pure once-through.
Water cost comparison: Closed-loop ZL-20T operating cost: USD 832/year energy + water. Once-through cost: USD 5,000-15,000/year water (depending on local rates). Closed-loop is 6-18x more cost-effective.
For injection molding facilities with significant water costs, ZL-20T closed-loop configuration delivers rapid ROI.

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.
