Non Intercooled Applications

At times, more commonly with refrigeration units, multiple stages of compression may be necessary due to the compression ratios, but may not require interstage gas cooling due to low discharge temperatures from the low gas k-value. Operating without an interstage gas cooler can be done with special considerations:

The suction temperatures to each stage, and mean cylinder gas temperatures must be limited as noted in the Suction Temperature topic.

All considerations for condensation have been reviewed and confirmed to avoid all condensation at the interstage. Condensate considerations include periods of shutdown and cool down.

A bottom suction cylinder arrangement may be possible on some applications to allow interstage piping routing from the top of one stage to the top of the next stage, avoiding areas that can trap liquids on the interstage.

All non-intercooled applications must be reviewed and approved by Ariel Mount Vernon prior to quotation.
