3.2 OPC UA for Compressed Air Systems terms

3.2.13 Main Function [of a Component]

The actual main function of Components is not specified in this specification. The following examples of Main Functions do not imply the actual function of the referenced Component.
EXAMPLE 1 Charging system: to keep pressure upstream above a set minimum pressure or within a set pressure range
EXAMPLE 2 Compressor: to deliver compressed air into the piping with an expected volume flow and at an expected pressure
EXAMPLE 3 Condensate drain: to remove condensate from the compressed air piping or a condensate storage to outside the pressure system
EXAMPLE 4 Condensate separator: to separate the hydrocarbon contents from the condensate to create a clean condensate that can easily be disposed of
EXAMPLE 5 Converter: to eliminates hydrocarbons from the compressed air stream to create class 1 (and better) oil free air
EXAMPLE 6 Cooling system: to reduce the compressed air temperature to a desired level
EXAMPLE 7 Dryer: to remove moisture from compressed air and dry compressed air to a pressure dew point below the required value
EXAMPLE 8 Filter: to remove particles and aerosols from the compressed air flow
EXAMPLE 9 Heat recovery system: Main function: to heat up a material or substance flow by using the heat generated by the compressed air system
EXAMPLE 10 Receiver: to store compressed air and provide a buffer
EXAMPLE 11 Sensor: to measure specific parameters in the compressed air system and provide the data
