Retrofit for isotherm turbocompressors
Guide Vane Actuating Unit
Optimised for maximum reliability
Horizontal installation of the guide vane actuating unit consisting of actuator and positioner
Assembly of guide vane actuating unit
As the previous actuating units for the guide vane adjustment at RIK turbocompressors did not prove the expected long-term reliability, MAN PrimeServ
developed a new actuator with an electro-pneumatic positioning unit. The new
guide vane actuating unit has been installed on all RIK turbocompressors since
2005. It is operating fully satisfactorily in more than 150 field installations and
recommended as a “plug & play” solution to all customers with previous installations of RIK turbocompressors.
