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.

Multi-press plant support: centralized cooling with predictable performance across all presses. For a 20-press plant with average 400-ton presses, ZL-10T array delivers total cooling capacity with standardized interfaces. Simplified spare parts inventory and operator training across the plant.
Closed-loop strongly recommended over once-through cooling. Benefits: stable cooling water chemistry, consistent temperature independent of city water variations, water consumption reduced 95%, reduced water cost, environmental compliance. Payback period: 2-3 years versus once-through cooling for most applications.
Variable load handling: stable 32°C leaving water maintained across 30-110% of nameplate capacity. Off-design performance: at 50% airflow (VFD), fan power drops to 12.5% of design (cube law), enabling 80% energy savings during shoulder seasons. Cycle time stability within ±1 second across load variations.
Tool steel compatibility: P20, H13, S7, S50C all supported with stable thermal management. For high-tonnage molds (HRC 48-52), cooling water temperature must remain stable to prevent thermal fatigue cracking. ANTEC technical papers confirm optimal heat extraction rates for high-tonnage automotive molds.
