The ZL-10T's 10 RT (35.2 kW) cooling capacity matches a single 200-ton injection molding press (the press tonnage rating, not cooling tonnage) for direct mold cooling without a chiller:
Heat load from a 200-ton press: Barrel heater (10-15 kW), hydraulic system (8-12 kW), mold cooling (10-15 kW), and miscellaneous (2-3 kW). Total: 30-45 kW.
ZL-10T matching: 35.2 kW cooling capacity aligns with the typical 35 kW heat load of a 200-ton press running at 70-80% utilization. For presses running >90% utilization, the ZL-10T is undersized — step up to ZL-15T (52 kW) or ZL-20T (60 kW).
Direct cooling (no chiller): For applications where mold temperature of 30-35°C is acceptable (commodity-grade parts, non-precision applications), the ZL-10T can deliver 32°C cooling water directly to the mold without intermediate chilling. This eliminates chiller capex (USD 5,000-7,000) and chiller energy consumption (USD 1,500-2,000/year) for a significant total cost reduction.
For injection molding factories operating their own scrap recycling, the ZL-10T + ZL-PC plastic crusher pairing creates a closed-loop material flow:
Step 1 — Scrap generation: Injection molding produces 5-15% scrap (runners, sprues, defective parts). Typical 200-ton press generates 50-100 kg/day of plastic scrap.
Step 2 — Size reduction (ZL-PC): ZL-PC180 (2.2 kW, 120-150 kg/h capacity) or ZL-PC300 (5.5 kW, 250-350 kg/h) crushes scrap into 5-8 mm flakes. Crushes PET bottles, PP containers, PE film, and engineering plastics (ABS, PC, PA).
Step 3 — Cooling the crusher: Plastic crushing generates heat through friction — bearing temperature rises 10-20°C above ambient. For continuous operation, crusher bearings require active cooling. The ZL-10T's 7.81 m³/h flow provides adequate cooling water for one ZL-PC180 or one ZL-PC300 crusher.
Step 4 — Recycled material: Crushed flakes are mixed with virgin resin at 10-30% ratio for re-injection. Cooling tower water temperature consistency (32°C ± 2°C) ensures consistent crusher operation and flake quality.
This closed-loop configuration is particularly valuable in regions where scrap disposal is expensive or regulated (Europe, Japan, coastal China).
For injection molding applications requiring precise mold temperature control (typically ±3°C), the ZL-10T pairs with a ZL-MTC mold temperature controller. The pairing is:
ZL-10T (primary cooling): Delivers 32°C water to the MTC's heat exchanger. The MTC's primary loop circulates cooling tower water to absorb heat from the secondary loop.
ZL-MTC (precise temperature control): Heats or cools the secondary loop to the precise mold temperature (typically 80-120°C for thermoplastics, 150-200°C for engineering plastics). Returns cooled water to the mold at the target temperature with ±1°C accuracy.
Typical MTC sizing for 200-ton press: 6-12 kW heating capacity, 0.37-0.75 kW pump. Common MTC models in this range: ZL-MTC6 (6 kW), ZL-MTC9 (9 kW), ZL-MTC12 (12 kW).
The ZL-10T + ZL-MTC9 pairing is the most common configuration for 200-ton injection molding lines, providing both primary cooling (ZL-10T) and precise temperature control (ZL-MTC9). Total cooling system cost: approximately USD 850 + USD 2,800 = USD 3,650 — substantially less than air-cooled precision chillers (USD 6,000+).
Injection molding machines' hydraulic systems generate substantial heat through pump inefficiencies and throttling losses. Typical 200-ton press hydraulic heat load: 6-10 kW. Without active cooling, hydraulic oil temperature can exceed 70°C, accelerating oil degradation and reducing system efficiency.
The ZL-10T can provide indirect hydraulic oil cooling through a plate heat exchanger:
Configuration: ZL-10T basin water circulates through plate heat exchanger; hydraulic oil circulates through the other side. Heat transfer rate: 6-10 kW per heat exchanger. The cooling tower water temperature must be 5-8°C below target oil temperature for effective heat transfer.
Oil temperature targets: 40-50°C for most hydraulic systems (above 50°C accelerates seal degradation; above 65°C risks oxidation). With ZL-10T delivering 32°C water, plate heat exchanger can maintain oil at 40-45°C under typical 6-10 kW load.
For plants operating multiple presses with shared hydraulic systems, the ZL-10T can serve both mold cooling and hydraulic cooling through separate plate heat exchangers. This shared cooling approach reduces total cooling system cost by 20-30% versus individual chillers per press.
Beyond injection molding, the ZL-10T serves plastic extrusion lines for film, pipe, sheet, and profile production:
Film extrusion: Typical 50-90 mm extruder generates 15-25 kW heat through barrel heaters and screw motor. ZL-10T provides primary cooling for the cooling rolls and chill rolls that set the film thickness and surface finish.
Pipe extrusion: PVC, PE, and PP pipe extrusion requires precise cooling water at 15-25°C for sizing and quality. ZL-10T delivers 32°C water which is acceptable for thick-wall pipe (>5 mm) but requires a chiller for thin-wall precision pipe.
Profile extrusion: Window profiles, decking profiles, and similar applications use the ZL-10T's 32°C water for calibration table cooling. Calibration table typically requires 3-5 m³/h flow per line.
Sheet extrusion: PET, PP, and PS sheet extrusion uses chilled water for roll cooling (typically 10-15°C). ZL-10T alone is insufficient; pairs with chiller for <15°C supply.
For facilities running multiple extrusion lines, a single ZL-10T can typically serve 2-3 small extruders (<60 mm) in parallel, distributing the 7.81 m³/h flow across multiple cooling circuits.
For plastic crusher installations, the ZL-10T provides bearing and motor cooling for the crusher's rotor shaft. Crusher heat loads:
ZL-PC180 (2.2 kW crusher): Rotor bearing heat load 0.3-0.5 kW. ZL-10T provides adequate cooling water at 0.5 m³/h flow per crusher.
ZL-PC300 (5.5 kW crusher): Rotor bearing heat load 0.8-1.2 kW. ZL-10T provides adequate cooling at 1.0 m³/h flow per crusher.
ZL-PC800 (30 kW crusher): Rotor bearing heat load 3-5 kW. ZL-10T is undersized — use ZL-30T or larger.
For a recycling line with one ZL-PC300 + one ZL-PC180, total cooling water flow requirement is 1.5 m³/h — well within the ZL-10T's 7.81 m³/h capacity. The remaining 6.3 m³/h capacity serves the injection molding press's mold cooling circuit.
For ZL-PC crusher buyers interested in adding on-site crushing capability, the ZL-10T + ZL-PC combination delivers a complete closed-loop recycling system without requiring separate chiller capacity.
The ZL-10T's 35.2 kW cooling capacity matches a single 200-ton injection molding press at 70-80% utilization. For presses >90% utilization, step up to ZL-15T (52 kW) or ZL-20T (60 kW).
Yes. ZL-10T + ZL-PC180 or ZL-PC300 forms a closed-loop recycling system. The cooling tower provides both mold cooling (7 m³/h) and crusher bearing cooling (0.5-1.0 m³/h).
For 200-ton presses, the ZL-MTC9 (9 kW) or ZL-MTC12 (12 kW) mold temperature controllers pair well with the ZL-10T. The ZL-10T delivers 32°C primary cooling; the MTC provides ±1°C precision control at 80-120°C for thermoplastics.
Yes. The ZL-10T cools hydraulic oil indirectly through a plate heat exchanger. For 200-ton presses with 6-10 kW hydraulic heat load, the ZL-10T maintains oil temperature at 40-45°C. Multiple presses can share a single ZL-10T through separate plate heat exchangers.
For film extrusion (50-90 mm extruder, 15-25 kW heat load), the ZL-10T is adequate. For pipe extrusion, the ZL-10T serves thick-wall (>5 mm) pipe but requires chiller for thin-wall precision pipe. For sheet extrusion, the ZL-10T pairs with chiller for <15°C supply.

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.
