An Austrian customer, a manufacturer of fiber composites for wind turbines, sporting goods, industry and the aircraft industry, uses our IP68 watertight air motors as a safety system for its piping system.

Our customer requires a temperature of 230 degrees to process the composite materials. To do this, he uses oil heated to 230 degrees. He sends this through his production process via pipes. Our powerful Radial piston motors are used to close the pipe system immediately in the event of leaks and prevent large quantities of oil from leaking and thus contaminating the environment. In addition, it closes large valves in its sewer system at the same time as our pneumatic radial piston motors to prevent oil from entering the sewer system.

The advantages of our radial piston motors for such applications with liquids and humid environments are easy to list:
The motors can be controlled easily and without electricity. They can be loaded to a standstill without the use of limit switches and controls. A simple changeover valve closes the pipe system as far as it will go and the motor stops. An electric motor would run hot here.
Thanks to their purely mechanical design and their IP68 waterproof construction, they can withstand the weather and system-related damp environment without any problems.
Furthermore, the valve can also be closed manually as a redundant option.

Before our customer modernized its safety system with our air motors, the employees had to close the 50 cm diameter pipes by hand. This took far too long, up to 3 minutes in an emergency. Today, our IP68 waterproof motors perform this task within a maximum of 45 seconds, even outdoors. Solenoid valves, controlled by monitoring sensors on a PLC, open the compressed air supply so that the radial piston motors can carry out their rescue work in an emergency.
