Case Study: Energy Efficiency Optimization in Tire Extrusion Cooling

High-Efficiency Air Supply for Tire Extrusion Cooling

ofile as it leaves the cooling bath. The legacy 22 kW side-channel blower carried three penalties:
Full power draw regardless of actual process demand.
Discharge temperatures of 60–80°C, harmful to the temperature-sensitive rubber compound.
Performance degradation where anti-tack agents are present.

Air-knife station in the cooling section of a tire extrusion line.
2. The Solution: X720 High-Speed Turbo Technology
Field measurement puts X720 efficiency at 80.3% at the measured operating point (14.1 kPa) — roughly three times the legacy blower at the same duty.
Parameter Legacy Side-Channel Blower X720 Turbo Blower Improvement
Nominal Power 22.0 kW 7.5 kW >60% Reduction
Operating Pressure Variable 14.1 kPa Precision Control
Discharge Temp. ~60°C – 80°C ~40.1°C Better Thermal Stability

3. Quantifiable Results and Operational Impact
Power: 7.0 kW measured input versus 22 kW — one-third, at unchanged air-knife velocity.
Temperature: discharge holds near 40.1°C, eliminating localized re-heating and preserving dimensional stability through the cooling phase.
Control: live pressure (14.1 kPa) and flow (24.1 m³/min) monitoring, adjustable to line speed.
4. Conclusion
Swapping a 22 kW side-channel blower for a 7.5 kW X720 removes more than 60% of the installed power at identical duty — cutting electricity cost and carbon footprint directly, with a rapid return on the investment.
X720: 7.5 kW · +200 mbar · 18 m³/min · 22 kg · IP55 · Class H · <80 dB(A) · CE certified (0P250923.GTCQ05).
