Developed by Techcross, ECS is a direct electrolysis BWMS and ECS-HYCHLOR is an indirect electrolysis system. These products utilize proprietary electrolysis technology to provide more perfect disinfection. They are top products recognized by the world for effective installation and swift customer response.

  • ECS

    ECS (Electro-Cleen™ System) is a BMWS using direct electrolysis technology. Since Techcross received basic approval from the IMO for the world's first BWMS in 2006, the company has been providing this optimal customer- acclaimed solution with easy installation, low maintenance costs, and experience-backed services.

    The sea water coming into the vessel passes through the ECU and is simultaneously sterilized through a direct electric process. The processed sea water goes to the ballast tank, where the remaining hypochlorite acid perfectly prevents the regrowth of microorganisms. Later during the deballast, the remaining TRO is neutralized to minimize the impact on the marine environment. Unlike during the ballasting, the sea water is directly discharged without going through the ECU during deballasting.


    HYCHLOR (ECS-HYCHLOR™ System) is a BMWS using indirect electrolysis technology. Techcross has enabled high efficiency for its proprietary electrodes; to respond to various customer needs, the company developed HYCHLOR, supported by another electrolysis method. HYCHLOR may be a good alternative for customers with a system with pipes that cannot directly host an electrolysis chamber.

    HYCHLOR is composed of filter units, indirect electrolysis units, neutralizer, and other devices. Using the AFU installed in the main pipes, the system removes sediments and microorganisms over 50㎛. Then, only 1% of the sea water taken into the ship is sent to the indirect electrolysis unit to generate high-concentration TRO, which is then sent back to the main pipes. The water is diluted to maximum TRO concentration of 5.0mg/L, with the goal of disinfecting remaining microorganisms. During deballasting, the later bypasses AFU, only neutralizing the remaining TRO to be sent outside of the ship.


    The key to electrolysis technology is in the electrodes. Techcross has proprietary technology on the electrodes, and the company can independently manufacture the devices, enabling quality and cost control. Strict quality control and manufacturing know-how are required to produce electrodes because all manufacturing elements from materials to coating liquid and methods determine the resulting performance. Techcross electrodes are made using catalysts with high reaction factors in fresh water with insufficient chlorides. Furthermore, Techcross uses a special coating method with higher efficiency that generates cracks on the surface of the titanium electrodes to ncrease the surface area. Also, electrodes lose their lifespan with more use because of scale buildup on the negative surface, which increases resistance and requires higher current to maintain the remaining oxidants. Techcross solved this problem by reducing the scale buildup by coating special materials on the titanium electrode surfaces.

    Low Power Consumption

    Techcross BWMS uses the proprietary high-efficiency electrodes, which lead to an extremely lower power consumption compared to competitor's (ECS consumes 3.4kW and HYCHLOR consumes 5kW for 100 tons of sea water). That is, no additional devices are required to manage power consumption; the lower power consumption means savings on operating costs.

    Convenient Installation

    The compact Techcross BWMS can be installed on various vessels regardless of type or size. The products can be flexibly installed in limited spaces, which means that minimal structural changes are needed, in addition to guaranteeing the best cost efficiency by reducing the installation time.

    Low Maintenance and Operating Costs

    Techcross BWMS treats ballast water only once during ballasting, which reduces operating costs and eliminates the necessity for regular part replacements. Techcross operates a reliability laboratory that enhances device and part durability to reduce maintenance costs.
