Engineering · Auxiliary — Air Compressors
Intercoolers between stages of a multi-stage air compressor are fitted to:
- AIncrease the air temperature for the next stage
- BCool the air between stages, improving efficiency and reducing work✓ Correct
- CRemove oil from the air
- DStore the compressed air
Explanation
Cooling the air between stages reduces its volume and the work the next stage must do, raises efficiency, and lowers discharge temperature — also helping drop out moisture.
