A 120 mm primary extruder paired with a 65 mm co-extruder produces more waste heat than any single-screw arrangement, and the tower must absorb all of it without drifting outside the process window. The VihoX 120 Ton unit moves 93.7 m³/h nominally and uses the larger 2,900 mm shell so the packing area keeps pace with that volume.
Airflow reaches 48,000 m³/h through a 2.2 kW axial fan with a sweep between roughly 1410 and 1800 mm. The wider blade set lets the fan turn more slowly for the same air volume, which is why the noise signature stays close to that of smaller frames. Returning water passes a rotary sprinkler, soaks the PVC pack, and settles in the base basin where a float valve holds the level steady.
All flow and approach figures assume 27 °C design wet-bulb, 37 °C hot water inlet and 32 °C cold water outlet, a 5 °C spread. Share your local climate data and we will verify the selection.
| Specification | VihoX 120T Data | Effect on Uptime |
|---|---|---|
| Nominal circulation | 93.7 m³/h | Covers a 120+65 tandem extrusion train |
| Suggested pump duty | 98.385 m³/h | Enough reserve for long return mains |
| Fan power | 2.2 kW | High air volume with a modest electrical load |
| Air volume | 48,000 m³/h | Sustains cooling as ambient humidity climbs |
| Fan diameter | Approx. 1410 to 1800 mm | Slow rotation, low vibration, quieter hall |
| Connection size | DN125 to DN150 | Choice of flange to suit existing pipework |
| Net weight | Approx. 530 kg | Delivered assembled for a single lift |
| Working weight | Approx. 1,690 kg | Confirm structural capacity at the mounting point |
| Overall dimensions | Approx. Ø2900 × H2500 to 2560 mm | Taller shell than the 100T at the same diameter |
| Recommended pump | 11 kW clean-water unit | Single set, inlet and outlet flanged |
Specify an 11 kW pump for 98.385 m³/h at 20 to 30 m head, then have your piping contractor confirm that figure against the installed route. With DN125 to DN150 ports there is scope to pick the flange that matches pipework already on site. Most tandem lines feed the calender stack, the embossing roll and the mould circuits from one manifold.
Not always. It depends on melt output, calender width and how many mould circuits run at once. Send us those figures and we will size it rather than estimate.
DN125 and DN150 both fit the outlet range of this frame, so you can match whichever flange your pipework already uses without an adapter.
With the pump and fan running together, the loop reaches its working range in a few minutes, well before the extruder is thermally stable.
One frame means one pump set, one electrical drop and one maintenance schedule. Two units only pay off when you need staged capacity or redundancy.
Yes. Fan speed can be reduced at lower heat loads, which cuts energy use while keeping the basin temperature stable.
A sprinkler head, a float valve assembly and fan bearings cover almost every routine failure on this frame.
If approach temperature widens noticeably at the same load and flow, scale or deformed fill is usually the cause. Inspect the pack before replacing it.
The shell is pigmented FRP rather than painted, and colour options can be discussed at order stage if you need to match plant branding.
Send the layer structure of your tandem line, the calender width and the target line speed, and our technical team will verify the 120 Ton duty together with the pump selection. You can also look at our co-extrusion sheet lines and three-station thermoformers to see how the same loop supports downstream equipment.

Adding a 20HP air-cooled chiller lets the tower work at bulk rejection while the chiller holds the set point. A 50HP PM VSD compressor serves the pneumatic side, and on the production side this frame is normally sized around cup making machines running multiple moulds.
