Ingersoll Rand has innovated the modular dryer category with desiccant dryers that are compact, fully integrated units which install at point-of-use; which means you pay for drying only the air required. Plus, fast and easy on-site maintenance.

For those looking for a low capital investment option; heatless desiccant dryers use twin desiccant towers with strategically positioned valves to dry compressed air. The 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.

Ingersoll Rand's externally heated dryers divert significantly less dry air from the air system for regenerating desiccant than is required by heatless dryers, resulting in increased energy efficiency while maintaining the reliability and safety of a heatless dryer.

Ingersoll Rand's heated blower desiccant dryers are equipped with dedicated durable centrifugal blowers to provide purge air for regeneration, which directs ambient air through an external heater and then through an off-line tower to regenerate the desiccant. This eliminates the need to divert dry compressed air from the system so more compressed air is available for critical downstream applications.

HOC dryers use heat already generated by the air compression process, which would normally be considered waste, making them the most energy-efficient type of desiccant dryer on the market. The Ingersoll Rand HC Series delivers -40°F (-40°C) pressure dew point air consistently under all load conditions at operating costs well below those of typical desiccant dryer designs
