The Turbo Air® 3000 Centrifugal Compressor Compressor Handbook

The Turbo Air 3000 Centrifugal Compressor Operator’s Manual
Surge — a compressor operating condition characterized by a momentary reversal of airflow back
through the compressor.
System Pressure — the pressure of the compressed air measured after the compressor check valve.
Transducer — a sensor that converts a measured parameter (such as pressure or temperature) to a
voltage output in an established way.
Transmitter — a specific type of transducer that converts a measured parameter (such as pressure)
to a current output (typically 4-20 mA).
Trip — a shutdown initiated by the Vantage Control System to protect the compressor.
Trip Recall Function — a Control Panel Diagnostics function that allows the operator to review
compressor operating data at the time of a compressor Trip condition.
Turndown Range — the extent to which the airflow through the compressor may be throttled without
encountering surge while maintaining setpoint pressure.
Unloaded — an operating condition where airflow through the compressor, and thus power
consumption, are at a minimum.
User Interface — the part of the Vantage Control Panel that allows the user the view data, monitor
compressor operating, and adjust operating parameters (such as setpoints).
“Worst Case” Operating Condition — the ambient circumstances (also referred to as a “hot
summer day”) when the air is less dense and filled with water vapor resulting in adverse compressor
performance.
