CleanSOx Compact

cleanSox compact

The optimal EGCS solution for SOx compliance The new CleanSOx Compact EGCS, through its significant size and weight reduction design allowed by the unique patented gas recirculation technology , brings maritime scrubbers to the next level. The compact size of this scrubber does therefore not necessitate or involve a major design change or rebuilding of a vessels to fit the equipment onboard. The CleanSOx Compact scrubber therefor represents the optimal solution for owners opting for scrubbers when considering parameters like: hybrid, Allstream, Size, Weight, Design and the Total Cost to have it installed and commissioned.

The patented CleanSOx EGCS is designed to meet the needs of the maritime industry and offers proven Allstream exhaust gas handling meaning all exhaust sources on board can be served by one common EGCS unit; enabling a fast return on investment.

 Our EGCS systems works equally well in open (liquid one time through) and closed (liquid recirculation) modes while seawater and alkali is used to regulate the sulphur trapping efficiency in both modes. The EGCS can operate in all types of water (including low alkaline and saline water) in either mode and without loss of efficiency. 

The CleanSOx EGCS is therefore an optimal solution for the marine environment and represents a futureproof system for the ship owner, adhering to regulatory variety in all waters. Our system has also the ability to combine natural and added alkalinity in open loop operation. This means it will provide high cleaning efficiency while maintaining a pH>6 at the outlet, making the effluent compliant with all IMO and regional/local regulations. The CleanSOx Compact EGCS are tailor made too any engine size and vessel.

Key features

 No back pressure: 

  • No fuel penalty
  • AE’s can start connected to EGC unit(s)
  • No restrictions running AE’s in part load – no impact on - engine parameters (EIAPP)
  • Boilers connected

Closed loop/open loop operation:

  • Open loop 0,5% Sulphur – sea water only when - Sulphur < 3,5%
  • Open loop 0,1% Sulphur – sea water + NaOH dosing; can transit any water – no alkalinity restrictions
  • Closed loop – sea water + NaOH dosing; only required - where zero discharge is called for pH
  • Open loop 0,5% Sulphur – process water + cooling water + dilution device
  • Open loop 0,1% Sulphur – plus NaOH (pH 6,5 at 4m or pH 6 - overboard) 

Footprint and savings:

  • Height reduced by 66%
  • Weight reduced by 30%
  • Cost reduced by 30%


  • Operates with one fuel in all areas and harbours
  • No need for major rebuilding of the vessel; minimum footprint requirements
  • Reduced installation and commissioning time
  • Future proof solution
  • Minimum CAPEX and OPEX
