Your start-up compressor solution
Offering high torque and high efficiency, the Vosycon, is the ideal start-up compressor solution.
The biggest challenge when large compressors are in operation is the start-up. Single shaft gas turbines don’t produce sufficient torque to accelerate the compressor. Furthermore, large electric motors often can’t be started due to the inrush current.
The Vosycon provides the perfect solution by disengaging the driver and load during start-up.

How the Vosycon works
Installed between the driver (turbine or motor) and the compressor, the Vosycon torque converter impeller is connected to the drive and the turbine wheel to the compressor. The unit disconnects the driver and compressor during startup, enabling an unloaded start. It should be noted that to facilitate this; the torque converter is drained.
Once the driver is up to speed, the torque converter is filled, and the Vosycon accelerates the compressor. By opening the Vosycon guide vanes, the compressor speed can be adjusted to the input speed. When the two speeds match, the lock-up device is engaged, which connects the driver and compressor mechanically. In this phase, power is mechanically transmitted at very high efficiency while the integrated gear provides the required speed increase for the compressor. After that, the load can even be further increased.
