Press release: Diinef technology enables launch of world’s first digital hydraulic motor with Imenco Bauer Hydraulics

Diinef, a specialist developer of advanced valve systems, has joined forces with Imenco Bauer Hydraulics to launch the world’s first digital high torque low speed hydraulic motor at Nor-Shipping 2017. Although it is both a young and relatively small firm, Diinef believes its valve technology has the potential to transform maritime efficiency, turning high torque low speed motors into digital motors – enhancing power, reducing energy loss and increasing energy efficiency.

Diinef develops and sells valve systems to manufacturers of hydraulic motors, with Imenco Bauer being both the Norwegian firm’s first customer and development partner. Its technology allows for simpler motor layout, significant cost reductions and enhanced monitoring, data sharing and overall control.

Per Lindholt, Diinef CEO, explains more: “In layman’s terms you can say that the addition of the valve system is like equipping traditional motors with electronic injection. But there’s much more to it..

“Having complete control of when oil is let in and out of each cylinder enables control functions not previously seen in hydraulic motors. Being able to disconnect cylinders not required makes it possible to change displacement and thereby control torque, speed or position, as well as enhancing energy efficiency. Additionally, this gives a range of features such as dynamic braking, hydraulic locking, freewheeling and reversing without the use of any extra valves. An extremely precise positioning is possible, within less than 0.25 degrees.”

Lindholt adds that the power output and power density of the motor can be doubled, and in some cases tripled, when compared to traditional solutions. He believes the benefits are compelling enough to shift the balance between hydraulic and electric drives in favour of pure hydraulic solutions.

“We see this as a game-changer for the maritime industry, with significant potential beyond that,” Lindholt concludes.

“This technology, with these advantages, is equally as relevant within any sector where high torque and controllability is required. We see no reason why industries such as mining, paper, plastic, waste, metal industry and renewable energy cannot enhance their performance, control and efficiency with Diinef’s valve systems.”
