Description

The Vertex-Pro is an anti-surge controller, designed to control and protect industrial-sized

motor-driven axial and centrifugal compressors. This purpose-built controller is available

in standard off-the shelf models or custom models. Standard off-the-shelf models are available

for one or two recycle loop applications, while custom models (Vertex-Pro-C models) are available

for larger three and four recycle loop applications.

OEM-qualified algorithms are used to ensure that proper start sequences are followed,

proper and accurate compressor load calculations are used, and proper protection and

recovery actions are performed.

Basic functionality includes:

 Motor Drive Interface Logic

 Inlet Throttle Valve Control

 Inlet Guide Vane Control

 Recycle Valve(s) Control

 Surge Control

 Performance Control (suction or discharge)

 Surge Anticipation Logic

 Surge Protection Logic

 Surge Recovery Logic

 Load Sharing
