Stack Presses
Our stack presses support the technical testing of fuel cell and electrolysis stacks. The pre-assembled stack, which consists of a large number of plates, is compressed to a defined height until a certain pressure is reached within the stack, and this pressure is then maintained unchanged for several hours.

Machine concepts
On the basis of the following machine concepts we find the optimum solution for you:
Precision with maximum safety
In order to be able to guarantee assembly work during operation with maximum safety, we avoid hydraulic drives deliberately. Instead, the stack is compressed inside the press by means of servomotor-driven spindle units. These are operated synchronously and thus enable particularly homogeneous compression of the stack.
A special feature is the compensation of production-related stacking tolerances. Stacking tolerances are unavoidable, but when the stack is compressed, they cause transverse forces which can damage the stack. In order to eliminate these and to build up an even pressure distribution within the stack, these transverse forces must be continuously compensated for during compression of the stack. This is done with short-stroke cylinders that are located under the spindle lifting elements.
