Hitachi Shipbuilding received 2 sets of high-pressure selective catalytic reduction (SCR) equipment orders

It is reported that Hitachi Shipbuilding has received an order from Dalian Marine Diesel Engine Co., Ltd. to supply two sets of high-pressure selective catalytic reduction (SCR) devices. This is the first exhaust gas emission equipment order from a major Japanese diesel engine manufacturer that meets the Tier III nitrogen oxide (NOx) emission standards that came into effect in January 2016.

The two sets of high-pressure selective catalytic reduction (SCR) devices received by Hitachi Shipbuilding will be installed on two 7999 DWT chemical tankers built by China Aviation Dingheng Shipbuilding Co., Ltd. for a European shipowner. The NOx reduction system will help users meet the Tier III Nox emission limits for the North American and Caribbean Emission Control Areas that have been in effect last year, as well as the Tier III Nox emission limits for the Baltic and North Sea that will be in force in 2021.
According to Jitsuhiro Yamaguchi, Director of Hitachi Shipbuilding and Marine Machinery and SCR Business Unit, "Hitachi Shipbuilding is the only commercial agent for SCR systems that has been officially certified by Mann Diesel and Turbo. Our goal is to make marine SCR systems a device that meets Tier III environmental regulations. Industry standard."
According to Hitachi Shipbuilding, the company is the only manufacturer that produces both two-stroke and SCR systems, and two high-pressure selective catalytic reduction (SCR) units are scheduled for delivery in October and November.

Vane Damper


The internal structural design is vane, vane damper is more suitable for soft close. ABD vane dampers are used to dampen drives, control speed, and many other applications. The damping direction of the vane dampers with continuous rotation can be clockwise, counter clockwise, or in both directions. Vane dampers are widely used in automobile interior decoration, household electric appliances, furniture and bathroom products, etc. Our dampers can make the movement of structures soft, quiet and safe to mitigate the impact, avoid the damage, increase the mechanical life, reduce noise, and improve product quality.


When the axis of rotation is moving, the blades that are connected to the axis of rotation rotate at the same time. The silicone oil in the oil chamber is squeezed between the blade andthe body to the back of the blade. The resistance formed by the pressure of the silicone oil to the area of the blade is the damping torque of the rotating shaft and the blade. The torque generated during rotation is determined by the oil viscosity, the pressure area of the blade and the clearance between the blade and the body.
