Profile: Digital Harvest, Inc. offers industrial use air compressors. Our products include reciprocating air compressors, Ingersoll-Rand air compressors, centrifugal air compressors, towable air compressors, and oil-free air compressors. We also offer air compressors in a wide variety of horsepower ranges from 50 HP up to 200 HP. We supply refrigerated dryers and desiccant dryers. Refrigerated air dryers work by chilling the air in an air compressor to a low temperature that causes moisture in the air to condense and form into droplets. These are then separated from the air and removed.
