Ariel Compressor Guaranteed Performa...

Obtain all guaranteed performance in writing from Ariel.

Ariel guarantees a single design point as calculated by the current version of the Ariel Performance Program for each compressor manufactured. All other performance is "expected" and not guaranteed. A gas analysis is required to validate this guarantee. At this guarantee design point, performance is based on gas conditions at the cylinder flanges free of pulsation effects.

Rated capacity and power are guaranteed to a tolerance of ± 3% for specific gravity between 0.50 (14.482 molecular weight) and 0.80 (23.171 molecular weight).

Rated capacity and BHP are guaranteed to a tolerance of ± 6% for any one or more of the following conditions:

1. Specific gravity greater than 0.80 (23.171 molecular weight)

2. Specific gravity less than 0.50 (14.482 molecular weight)

3. Suction pressure less than 10 psig (0.7 barg)

4. Discharge pressure greater than 2500 psig (172.4 barg)

5. Compression ratios less than 1.8

Where:

• Molecular or Molar Weight of dry air (U.S. Standard Atmosphere) = 28.964

• Molecular Weight = Relative Molecular Mass

• Specific Gravity or Relative Density = Molecular Weight of gas divided by 28.964
