Having established a firm position on the market for supplying scrubbers and water treatment systems, Langh Tech is now expanding its water treatment technology to new areas.
Langh Tech has been working in close cooperation with MAN Diesel & Turbo (MDT) to develop a water treatment system to be used for cleaning the process water of Exhaust Gas Recirculation (EGR) systems. EGR is a method to reduce NOx emissions to meet Tier III requirements. In the EGR process, approximately one third of the exhaust gas is recycled back into the engine, first removing the particles from the redirected gases with a small scrubber. The process water from exhaust gas washing is continuously cleaned during EGR operation and this is where Langh Tech’s water treatment technology is applied. Langh Tech water treatment is based on membrane filtration, meaning that the operational costs are kept low and the waste consists only of small amounts of compact dry sludge.
Langh Tech, the Finnish manufacturer and supplier of scrubber solutions, will deliver scrubber systems to two large cruise vessels.
Two newbuildings of the Breakaway Plus class on order at Meyer Werft in Papenburg for Norwegian Cruise Line (NCL) will be equipped with scrubber systems from Langh Tech. The scrubbers are of hybrid type, enabling unrestricted operation in closed loop mode. The delivery includes scrubber units for all five engines on each ship and treatment plants for the scrubber water. ”The scrubber tower is of our design but will be manufactured at the shipyard. The components for the water treatment plant will be manufactured at our production facility at Piikkiö, Finland, and delivered to the shipyard,” Laura Langh-Lagerlöf, Commercial Director of Langh Tech, explains.
Supplying the cruise industry with environmental technology is a new land winning for Langh Tech. Prior to the order for the NCL vessels Langh Tech delivered water treatment systems for scrubber water...
Langh Tech has bought Deltamarin Ltd’s share of the previously jointly owned DeltaLangh Ltd, which manufactures scrubbers and water treatment systems.
”The cooperation with Deltamarin continues and Deltamarin Floating Construction can still provide turnkey scrubber installations”, states Laura Langh-Lagerlöf.
The method developed by Langh is based on an environmentally friendly closed-loop scrubber that can also be used in open-loop mode. “The hands-on experience has been excellent. We can see that the closed-loop water treatment system can, as it is a reliably functioning and an affordable solution, offer a very good opportunity for updating also other manufacturer’s scrubbers in order to meet the tightened regulations”, tells Langh Group’s managing director Laura Langh-Lagerlöf pleased.
From 1 January 2016 the scrubbers and the water treatment units carry the trademark Langh Tech. Sauli Vahtokari from Langh Group’s production sees the change very positive. “I believe that throug...
