Class StartupProfile

java.lang.Object
neqsim.process.equipment.compressor.StartupProfile
All Implemented Interfaces:
Serializable
public class StartupProfile extends Object implements Serializable
Defines a startup profile for compressor startup sequences.

This class defines the sequence of speed/time points that define how a compressor should be started. It includes safety checks and holds during the startup process.
