Step up from the smallest frame and the arithmetic changes quickly: extrusion output rises, mould count rises, and the cooling loop has to shed noticeably more heat. The VihoX 60 Ton tower balances that load with a 46.8 m³/h nominal flow, which is the volume most 105 mm and 110 mm single-screw PP/PS sheet lines need once their three-roll stack and mould circuits are included.
Air movement comes from one 1.5 kW axial fan capable of 25,200 m³/h, drawn upward through the fill pack for maximum contact time with falling water. Distribution uses a rotary sprinkler head rather than fixed nozzles, which avoids the dead spots that appear when spray patterns drift. The basin is moulded into the base and refills through a float valve, while the surrounding casing uses glass-reinforced plastic to shrug off condensation and airborne plastic dust.
The published duty is quoted at a 27 °C wet-bulb design point, with hot water arriving at 37 °C and returning to the process at 32 °C, a spread of 5 °C. Sites with a higher wet-bulb may need one frame larger.
| Operating Figure | Recommended Setting | Practical Reading |
|---|---|---|
| Circulation rate | 46.8 m³/h | Covers a 105 or 110 mm single-screw extrusion line |
| Pump flow to specify | 49.14 m³/h | Allows for elbows, valves and long return runs |
| Fan power | 1.5 kW | Same motor as the 40T, so spares stay interchangeable |
| Air throughput | 25,200 m³/h | Holds approach on typical Asian summer wet-bulb |
| Fan sweep | Approx. 1150 mm | Balanced blade set keeps vibration low |
| Connection size | DN100 | One size up from the 40T for lower velocity |
| Shipping weight | Approx. 240 kg | Crated in one piece, forklift accessible |
| Filled weight | Approx. 1,250 kg | Confirm slab loading before commissioning |
| Envelope | Approx. Ø2145 × H1960 mm | Fits most mezzanine-mounted installations |
| Recommended pump | 5.5 kW centrifugal | Vertical or horizontal body, single set |
Specify a 5.5 kW clean-water centrifugal pump for 49.14 m³/h at 20 to 30 m head, then have your piping contractor verify the real figure against the installed route. The DN100 ports accept standard flanges. Common practice is to feed the three-roll stack and the mould loop from one manifold so both see the same supply temperature.
One 60T usually wins on pipework, floor area and maintenance count. Two smaller units only make sense if you need staged capacity or complete redundancy.
Choose a clean-water centrifugal pump whose duty point sits near its best efficiency area at that flow and your measured head, not at its maximum rated output.
Yes. The 110 mm class is exactly the band this tower was sized for, together with its calender stack and mould circuits.
Evaporation tracks the heat load, and drift adds a small fixed amount. The automatic make-up covers both without operator attention.
Isolate the tower, drain the basin, then flush the pack from the top with low-pressure water. Avoid high-pressure jets, which deform the PVC sheets.
The 60T ships as one assembled body. If access is tight, tell us the opening dimensions and we will advise on site assembly options.
Standard supply is 380 V, 50 Hz, three phase. Other voltages and frequencies can be built to order.
Yes, and it is common. Balance them with a manifold and individual valves so neither circuit starves the other.
Send your extruder model, calender configuration and mould count, and we will size the 60 Ton tower and its pump against your actual heat load rather than a rule of thumb. Browse our sheet extrusion lines and three-station thermoformers to see what else the same cooling loop can serve.

Pair this frame with a 5HP air-cooled chiller when part of the circuit needs a tight set point rather than bulk rejection. The pneumatic side is normally a 20HP PM VSD screw compressor, and the heat load typically comes from mid-size cup making machines.
