Fuji Innovative Laser SCRUBBERS

Laser Gas Analyzer for Ship Scrubbers(SO2/CO2)

Innovative laser technology surpasses many performances of traditional infrared ray gas analysis. Its stable measurement with almost no drift allows to be free from frequent calibration and gas cylinder reservation on board. In addition, maintenance costs are less than half of those required when using conventional analyzers.

This lightweight and compact unit can be installed easily without taking care of heating tube.

Features a compact and lightweight cyclone design with low pressure loss

Regulations on emissions of sulfur oxide (SOx) and particulate matter (PM) in exhaust gas are being gradually strengthened by the International Maritime Organization (IMO).

Although ships need to use low sulfur fuel oil to comply with the regulations, operators have been concerned that price differences between conventional high sulfur fuel oil and low sulfur fuel oil will increase their operating costs.

With the recognition of exhaust gas cleaning systems (EGCS) by the IMO, these systems are accepted as equivalent measures for reducing emissions and they enable the continued use of high sulfur fuel oil.

It functions as,


  • Open-loop system
    • While the ship is underway on the ocean, an open-loop system is operated in which seawater is pumped in for use and can be drained back into the sea. An open-loop system uses less auxiliary equipment and helps keep the investment burden smaller,


  • Hybrid system (Open-loop and closed-loop switchover)
    • When the ship is in a drainage-regulated area such as in coastal regions or rivers, the system is operated in closed-loop mode in which the used seawater is treated with a chemical and reused. A hybrid system can operate in either open-loop or closed-loop modes.


  • Compact design
  • High desulfurization efficiency
    • The world’s first SOx scrubber with a cyclone design. The highly diffused spray of wash water inside the unit increases the area and time of contact between the exhaust gas and water.
    • Fuji Electric has been granted a patent for the technology used for this product (US 9770690 B2, KR 101570466 B1).
  • Low pressure loss
    • The cyclone design features a simple structure that uses only spray nozzles inside the Sox scrubber.
  • Occupying less space gives it a major advantage with easy installation
  • Stable performance & longer maintenance cycle
  • Compatible with all sea areas
