“I am pleased with the cooperation with POLNA S.A. hitherto. The following systems were implemented in the previous years: PN 250 pneumatic actuators replaced GULDE actuators and have, so far, been working successfully. This was possible owing to the very good cooperation with our design and marketing department. Production of these actuators differed from standard / catalogue production. Mobility and willingness to cooperate on your side allowed performing this task.”
