Sales Launched of Newly Developed “Mitsubishi Selfjector-Hercules Series” of Oil Purifiers

Mitsubishi Kakoki Kaisha, Ltd. (MKK; President: Kikuo Yamanaka) has developed a new series in its lineup of “Mitsubishi Selfjector” oil purifiers, one of the company's main products. The “Mitsubishi Selfjector-Hercules (SJ-H)” is the first new series of oil purifiers developed by MKK in the last ten years (please see the attachment for product photographs). Sales began this month, with deliveries to commence in July 2013.
The new SJ-H series builds on the excellent reputation gained by the Mitsubishi Selfjector Genius (SJ-G) series for its stability and reliability. By integrating new technologies like higher centrifugal force and highly efficient new separation disks, the new SJ-H series was developed to offer even higher quality and greater stability, yet at the same time to reduce running costs.
The SJ-H series purifier is even more compact than its predecessor, and each model in the new lineup reduces overall sludge discharge volumes, an important feature in light of increasing environmental concerns. Models include the “H-HIDENS” type, which employs a new operating algorithm and is highly reliable for purifying low-grade heavy fuel oil; and the “SUPER HIDENS” type, which can discharge the separated water without opening and closing the main cylinder in bowl.
The quality of heavy fuel oils used in large marine diesel engines has changed dramatically over the years. Advances in oil refining technologies have enabled low quality oils with specific gravities close to that of water and containing high amounts of particulate matter to be used as fuel.
Mitsubishi oil purifiers employ high-speed centrifugal force to separate particulate matter and water from low grade fuel oils, and lubricants. Centrifugal separators discharge the separated matter outside the devices continuously, which are used primarily for large-scale marine and land use diesel engines, onboard ships or at inland diesel power plant.
MKK first developed and began selling the Mitsubishi oil purifiers in 1942. They are now being widely used in various industries, helping to prevent engine trouble and ensure stable operations. Over the decades, MKK has produced and delivered a total of 93,000 units of these devices (as of August 2012), which are colloquially referred to as OP (Oil Purifiers) or SJ(Selfjectors). The newly developed SJ-H series is the eighth generation.

(Some features of the SJ-H series are described below).

  • Full lineup includes eight models capable of processing up to 22,500 L/Hr (380 mm2/s @50℃), which is a considerable increase over the SJ-G series (nine models capable of processing up to 14,500 L/Hr).
  • Compact size and lightweight construction means 20% less space required for installation (compared to MKK’s earlier series of oil purifiers).
  • Compact bowl and more efficient replacement; 30% less discharge (compared to MKK’s earlier series of oil purifiers).
  • As with earlier Mitsubishi oil purifiers, the “H-HIDENS” system can process up to 1,010 kg/m3 of highly dense, low grade fuel oil; however, the adoption of a new algorithm enables the SJ-H series to cut down further of total discharge volumes.
  • Includes the “SUPER HIDENS” model, which can process separated water within the bowl without requiring any discharge via operation of the main cylinder (when processing oils with high water content (bigger than 0.5 vol.%) under the ISO8217 fuel standard.
  • Employs the pilot valve mechanism, of which MKK has produced 50,000 units.
  • Comes standard equipped with gear pump for processing low viscosity fuel oils.
  • Improved operation thanks to multi-monitor display showing flow rate, temperature, pressure and other information.
