Heatless Desiccant Dryers
Air Compressor Dryers
If you are looking to purchase an air compressor, you most likely will also need a compressed air dryer. Water is a natural by-product of any compressed air process. When air is compressed, the moisture that is naturally present in the air is also compressed. When air leaves an aftercooler and moisture separator, it is typically saturated and as it cools while moving through distribution piping, it can condense, causing corrosion, contamination and other detrimental effects that result in low productivity, high maintenance costs and excessive downtime.
Ingersoll Rand Heatless Desiccant Dryers
IR heatless desiccant dryers use twin desiccant towers with strategically positioned valves to dry compressed air. The simple technology of heatless dryers divert a portion of dried compressed air to an off-line tower. The dry air then flows through and regenerates desiccant. Although operating costs run higher than the heated desiccant dryers, the HLA series requires the lowest capital investment.
Available in flows ranging from 2.5 nm3 /min. (90 scfm) to 141.6 nm3 /min. (5,000 scfm), Ingersoll Rand HLA heatless desiccant dryers are designed to ensure a constant -40°C (-40°F) or optionally -70°C (-100°F) pressure dew point, virtually eliminating costly interruption of production due to moisture. Clean air is further assured by use of strategically placed filters: a pre-filter to remove oil and contaminants in air entering the dryer, and an after-filter to make sure that only clean dried air exits the dryer.
