Ariel Compressor Performance Testing

1. Testing for guaranteed performance must occur within 90 days of commissioning. If the design

point cannot be reached in this time frame, a mutually agreed upon alternate point will be tested.

2. In questions of capacity delivered or horsepower consumed by an Ariel compressor, check these

common discrepancies: inlet pressure drop, excessive interstage pressure drop, leaking bypass

valves, volume decrease due to liquid drop out, gas analysis different than the quoted gas analysis,

compressor and driver mechanical condition, driver fuel gas consumption, etc.

3. If doubt still remains, conduct a performance test. Ariel reserves the right to conduct or supervise

any performance field test. All comparisons to predicted performance will comply with this document.

Ariel is not responsible for test costs.
