Introducing …the next generation in natural gas compression.

The New E-Select CA Series.

A Unique CombinationCaterpillar Engine Electric Motor Ariel Compressor

Patented technology combining a natural gas engine AND an electric motor coupled to a compressor packaged on one skid.

How it Works…A Unique Combination

After ignition, the natural gas engine is brought to operating speed with the electric motor spinning.

At a specified rpm, the motor takes over the compression load.

A clutch engages to allow the natural gas engine to coast while “cooling down” as it slows to a stop.

A Unique Combination

Transfers or load shifts are made between the engine and motor via remote controls or manual “at site” operations.

There is virtually no interruption of gas flow during transfers back and forth between the engine and motor.
