This dryer features a unique refrigeration technology

By Chemical Engineering |

Ingersoll-Rand

The Subfreezing Dryer (photo) provides a –4ºF pressure dewpoint at 70% lower energy costs and 40% smaller footprint than that of traditional desiccant dryers, says the manufacturer. The Subfreezing Dryer is compatible with oil-flooded rotary compressors, oil-free rotary compressors, centrifugal compressors and reciprocating compressors. This new dryer technology provides very dry air without wasting energy or purging compressed air. Furthermore, maintenance costs are reduced when compared to traditional regenerative desiccant dryers and drum dryers. The Subfreezing Dryer requires no costly periodic desiccant replacement, and with no desiccant required, downstream particulate filtering is not needed. — Ingersoll-Rand plc, Dublin, Ireland
