For more information about available capacities, please check the table shown below and go to the Defender 500 documentation section to download the product data leaflet. The Defender 500 has a capacity of up to 500 litres of blow-by gas per minute and is recommended for diesel and gas engines with displacements higher than 16 litres.
The Defender 500’s capability to minimize oil aerosols and soot particles in crankcase gas will help builders of industrial diesel and gas engines for a broad range of applications to comply with the more stringent global emission regulations (Tier 4, for example) coming into force from 2015 onwards. The Defender 500 will provide high cleaning performance and maintenance-free operation for the toughest engine duties. Special features make the Defender 500 highly resistant to higher operating temperatures and allow operation at various angles, conditions often encountered in marine, offroad or rail applications. Cleaning efficiency is more than 98% which is superior compared to most oil removal technologies. Only clean blow-by gases are then returned to the engine turbo or to the ventilation outlet. Oil droplets and soot are removed from the blow-by and returned to the oil sump. The Defender 500 uses centrifugal separation technology to clean the ventilated crankcase gases. Among others, it can be installed on construction vehicles, workboats, ferries and genset power stations.ĭefender 500 fulfills emission legislation, ensures environmental and health safety as well turbo protection for CCV applications and it is maintenance free. The unit is designed for built-on installation on off-road, marine, rail, military and stationary engines covering a wide range of industries. By protecting the turbocharger and intercooler, the Defender 500 helps maintain high engine performance and prolong engine life for closed ventilation systems (CCV). It serves as a complete engine crankcase ventilation system, including cleaning of gases and built in crankcase pressure control. The Alfa Laval Defender 500 oil mist separator minimizes crankcase gas emissions.
