OCM Oil Cleaning Module

The Alfa Laval Oil Cleaning Module (OCM) is a modular oil purification system that continuously removes water, sludge and solid particles from mineral lubricating and hydraulic oils. At its heart is a high-efficiency Alfa Laval disc-stack centrifuge, supplied on a compact, pre-configured skid that is easy to install, operate and maintain.

Product Benefits

  • Water and solids removed together: The centrifuge separates free water, sludge and solid particles at the same time, on a continuous basis.
  • Less wear and corrosion: Clean oil reduces abrasion, friction, filter clogging and corrosion on the equipment downstream, helping avoid breakdowns and downtime.
  • Longer oil and equipment life: Continuous purification extends the service life of both the oil and the machinery it protects.
  • Lower running costs: Reduced oil consumption, no filter cartridges to dispose of and lower disposal costs keep operating costs down.
  • Simple to live with: A robust skid-mounted design with an easy start-up procedure, low maintenance requirements and easy access.

Where It's Used

  • Steam turbines: Continuous cleaning of turbine lubricating oil, with capacity sized to the turbine's total oil charge.
  • Hydraulic systems: Hydraulic oil circuits where contamination clogs filters and wears components.
  • Steel and paper industries: Cleaning lubricating and hydraulic oils in steel mills and paper machines.

Good to Know

  • Five models: The range covers OCM 103, 104, 304, 305 and 206, each with a different cleaning capacity, in mobile or stationary versions.
  • Standard equipment: Each unit comprises a disc-stack centrifuge, separator motor, electric heater, feed pump, starter and control unit, and a mobile or stationary frame.
  • Separation performance: The system typically removes about 90% of the water and 90% of particles of 5 microns or smaller, along with about 70% of particles of 3 microns or smaller.
  • How it runs: Clean oil and separated water discharge continuously, while sludge collects in the bowl and is removed at regular intervals; the module can keep cleaning even while the main equipment is stopped.
  • Installation and support: Normally installed in a by-pass loop or tank to tank, and backed by Alfa Laval preventive maintenance, technical support, operator training and genuine spare parts.
