Air System Troubleshooting Guide

If your
system is:

Experiencing High Dew Point (as indicated by the dew point monitor) Providing Low Performance Experiencing Frequent Starts and Stops Shutting Down Due to High Temperature Experiencing High Amp Draw and Motor Trip Out Lag Alarm Going Off (multiplex systems) Desiccant Dryer Going into Switching Failure

WE SUGGEST YOU CHECK THIS:

A. The system may be equipped with a storage tank that is too small for the demand. The tank acts as a "buffer" between the compressor and the point of demand. If the tank is too small, the compressor will start and stop excessively to keep up with demand.

B. The total demand may be more than anticipated for the system design. Similar to point A above, the facility demand may exceed what the compressor and storage tank were designed to provide. This may be corrected by upsizing existing compressors or adding another compressor and larger storage tank.

C. The system's pressure switches may be set too close together. The wider the pressure switch settings, the longer the compressor will have in the off cycle between starts. With close pressure switch settings, the compressor will frequently start to maintain the desired pressure.
