The Alfa Laval Oil Cleaning Module Ex (OCM-Ex) provides rapid, effective separation of the oil, water and sludge components in contaminated mineral lubricating and hydraulic oils – all at the same time. The ex-proof module is designed for operation in ATEX II 3 G (Zone 2) II B T3. The benefits include lower operating costs due to reduced oil consumption, lower disposal costs and improvements in both product quality and the working environment. The Alfa Laval Oil Cleaning Module is a modularized system with all the components fully integrated, ensuring easy operation. At the heart of this compact, easy-to-use equipment is an Alfa Laval disc stack centrifuge of supreme efficiency. Alfa Laval Oil Cleaning Modules are available with all components and systems pre-configured on a skid, for easy, rapid installation and ready for immediate use. They ensure the effective removal of particles and water in the oil. If an emergency arises, even a high level of water contaminants can be removed. An OCM provides continuous purification of lubricating and hydraulic oils while the equipment using the oil is in operation. If required, the OCM can continue operating while the primary equipment is at a standstill.
