Langh Tech designs and produces scrubbers for SOx removal from exhaust gases and water treatment units for closed loop scrubbers.
The water treatment units can be delivered also in combination with other manufacturers’ scrubbers. This unique water treatment method enables continuous closed loop operation causing only a minimal amount of sludge and hence reducing waste removal costs. The efficiency of the water treatment method is recognised throughout the shipping industry from cargo ship owners to cruise ship operators.
The closed loop process is based on wet scrubbing with fresh water and using sodium hydroxide (NaOH) for neutralising sulphur. In open loop mode sea water is used in the exhaust gas washing process. The small and lightweight Langh Tech scrubber can replace the silencer. The scrubber and water treatment units are designed for both retrofit installations as well as new buildings.
In addition to component delivery, Langh Tech takes care of commissioning and offers installation supervision, crew training and after-sales services.
Langh Tech’s mission is to find the best solutions for cleaner air and seas for the coming generations. We work tirelessly to seek out the most effective methods to reduce SOx emissions and waste in the maritime industry.
The research and development of Langh Tech technology stems from a strong history in industrial cleaning technology. It is the latest of Langh companies, established to provide technical advantage to combat exhaust gas emission and related waste management in all types of ships.
STRONG ROOTS IN INDUSTRIAL CLEANING AND MARITIME
Langh Tech is one of the Langh companies, which also include ship owning Langh Ship, steel carriage and bulk containers from Langh Cargo Solutions and Industrial and Ship Cleaning Services Hans Langh. The knowledge for water purification originates from the industrial cleaning company that Hans Langh started in 1973.
The work of Hans Langh, founder of the Langh companies, is characterized by innovation and the desire to find new solutions to practical problems. The Langh companies have grown to provide solutions in agriculture, seafaring, transportation and industrial cleaning. The insight gained through decades of experience gives the Langh companies the edge in technological solutions. Langh Tech is one of these prime examples.
LEADING THE WAY WITH STATE OF THE ART SOX REMOVAL TECHNOLOGY
Langh Tech started with the scrubber development project during year 2011, when there was a need to find alternatives how to solve the upcoming 0,1% sulfur in fuel limit for Langh Ships vessels. Langh Tech started to develop a fully closed loop scrubber, where water treatment plays a key role. The first full scale closed loop installation was done in May 2013. Further development lead to a hybrid scrubber with the option to operate the system also in open loop.
