2 Structure and Specifications of the Compressor
Screw Compressor J-series 2.8 Variable Vi Control
2-30
2.8.3.2 Fixed Vi Mode
The J-series also allows for fixed Vi if the operating conditions are stable and the automatic variable Vi
control is not necessary.
Note, however, a specified controller is required to adjust the variable Vi slide valve to the desired Vi
value. It is able to set Vi to the following three ports: L port (Vi=2.5), M port (Vi=3.5), H port (Vi=5.0).
Note 1: For the J-series, a specified controller is always required.
