Manufactured in Europe, the new range of Ingersoll Rand desiccant dryers includes two main configurations, heatless and with heated blowers.

Ingersoll Rand desiccant dryers are designed to eliminate costly production interruptions which can result from moisture. All of the dryers use twin desiccant towers and strategically positioned valves for drying compressed air. The basic difference between the two dryer technologies is the manner in which moisture is desorbed from the desiccant, also known as regeneration. Heatless dryers use compressed air to purge the towers of moisture while heated blower dryers utilize externally heated ambient air. Heatless dryers are lower in capital investment, but may be more expensive to operate because they require a portion of the dried compressed air to be diverted from the air system for desiccant regeneration. Heated blower dryers require the highest initial capital investment due to the centrifugal blower, but with little or no diversion of compressed air from the system for regeneration, they offer significantly lower operating costs.

Energy consumption is a major consideration for both heatless and blower desiccant dryers. They are available with the Energy Management System (EMS). This reduces purge air consumption by monitoring dryer performance in low demand situations. While maintaining a constant dew point, EMS extends the dryer cycle so as to initiate the desiccant purge only when needed. On IB models (with blowers) the heater and blower are controlled by outlet regeneration temperature that shuts off to save electrical power once desiccant has been thoroughly regenerated. The solid-state soft starter limits the inrush current, reducing electricity consumption and making for a smooth start that extends motor life.

Both heatless and heated blower dryers have several standard features to guaranty high quality operation as well as options to customize dryers to fit the needs of your air system. Dryer operation can be run with 50 Hz, 60 Hz, and pneumatic (IL models only) power supplies. They are equipped with a digital electronic multi-function controller controlling valve switching as well as monitoring dryer operations. They are Modbus compatible and have an LCD display for easy viewing.
