The Alfa Laval Oil Cleaning Module (OCM) provides rapid, effective separation of the oil, water and sludge components in contaminated mineral lubricating and hydraulic oils.

OCM 640x360

The Alfa Laval Oil Cleaning Module (OCM) has been designed to rapidly and effectively separate the oil, water and sludge components in contaminated mineral oils used throughout industry for lubrication and in hydraulics. If an emergency arises, even a high level of water can be removed.

The Alfa Laval OCM unit is a modularized system with all the component systems fully integrated and pre-configured on a skid, for easy, rapid installation, and ensuring unattended operation while engaged on oil cleaning duties. At the heart of this compact, easy-to-use equipment is an Alfa Laval solid bowl disc stack centrifuge of supreme efficiency.

An OCM provides continuous purification of oil while the equipment in which it is used is in operation. If required, the OCM can continue operating while the primary equipment is at a standstill.

The importance of clean oil

Clean oil is crucial for the safe, reliable and economical operation of virtually all kinds of equipment that uses oils for either lubrication or hydraulic systems. Clean oil reduces wear and corrosion on all equipment installed downstream, thus helping to avoid breakdowns and cutting back on downtime throughout a plant or installation.

The benefits include lower operating costs due to reduced oil consumption, lower disposal costs and improvements in both product quality and the working environment.

How it works

The oil cleaning module is normally installed in a by-pass system, treating a specified percentage of the full flow of contaminated oil.
Tank-to-tank installation is also possible.

Separation takes place in a disc stack centrifuge. The feed is pumped into the centrifuge where centrifugal force separates the feed liquid into its different phases.

The heaviest of these phases – sludge and water – are forced to the periphery of the bowl. The sludge component is deposited in the sludge space and must be removed manually at regular intervals. The clean oil and the separated water are discharged on a continuous basis.
