Alu Treater

Precision Chemical for Cold Rolling 

In aluminum cold rolling, process oil purity is essential. Contaminants such as water and fine particles increase conductivity, clog filters, and destabilize the oil. Left untreated, this leads to shorter filter cycles, higher consumption, reduced strip quality, and increased operating costs.

No Changes needed

Alu Treater is a breakthrough additive engineered to continuously purify process oils. By keeping systems cleaner, it helps improve efficiency and supports compliance with environmental standards. Also it is a very simple way to improve your cold rolling operations.

  • Keep your oil.
  • Keep your filtration system.
  • Apart from a simple dosing unit, no additional equipment is required.

How Alu Treater works

Alu Treater is designed for continuous purification of rolling oils. By stabilizing conductivity and binding microscopic contaminants into filterable clusters, they safeguard oil quality, protect equipment, and reduce costs – all without additional hardware investment.

  • Stabilizes Conductivity – Neutralizes soaps and alkaline residues, keeping conductivity within the optimal 100–500 µS range.
  • Aggregates Contaminants – Binds soot and fine metal particles into larger, filterable clusters.
  • Improves Filtration – Reduces DP rise, extending filter cycle
  • Improves output Quality – Cleaner oil maintains strip surface integrity and rolling efficiency.

Lucent Alu Treater has a clear impact on the conductivity of cold-rolling oils. In untreated systems, conductivity typically continues to rise, often reaching levels above 750–1000 µS. Such high values indicate a destabilized oil system, increased filter load, reduced process stability, and a higher risk of strip surface defects.

With Alu Treater, the oil stabilizes quickly. Within 15 minutes from adding Alu Treater, conductivity drops significantly and levels off around 100 µS. During operation, values remain within the optimal range of 100–300 µS for about 90% of the time and rarely exceed 500 µS.
This balanced stabilization ensures cleaner oils, extended filter cycles, and consistent rolling performance – delivering measurable improvements compared to untreated oils

More on Conductivity

While high conductivity signals a destabilized oil system, excessively low conductivity can also be problematic. If the oil’s conductivity drops below approx. 50 µS, electrostatic charges generated in the rolling gap may not dissipate effectively. This increases the risk of static build-up, sparking, or electrical discharges. In extreme cases, such discharges can lead to strip surface markings, disturbances in strip tracking, or even safety hazards in the mill environment. By keeping oil conductivity within the balanced range of 100–300 µS, Lucent Alu Treater ensures both process stability and operational safety.
