Project Description

CleanSOx Compact

The optimal EGCS solution for 

Through its significant size and weight reduction design allowed by the unique patented gas recirculation technology, CleanSOx Compact 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 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.

Efficiency and fast ROI

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.

Future-proof system

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


  • 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 at overboard)
