Ingersoll Rand Introduces New Energy-Saving Dryers for Small Compressed Air Systems
Ingersoll Rand rolls out D-EC Series refrigerated cycling dryers for energy-conscious manufacturers
DAVIDSON, N.C., February 27, 2013 – Ingersoll Rand,  a world leader in creating and sustaining safe, comfortable and  efficient environments, is introducing a new line of energy-saving,  refrigerated compressed air dryers. The Ingersoll Rand D-EC Energy-Saving Refrigerated Compressed Air Dryers are available in eight models, ranging in capacities from 10 to 125  standard cubic feet per minute (SCFM). The D-EC dryers are ideal for  small commercial compressed air users such as machine shops, automotive  repair and refinishing businesses and light manufacturing applications.
The D-EC cycling dryers incorporate a thermal mass that stores cold energy, providing enhanced  operating efficiency over competitive non-cycling products in this  range. The thermal mass cools the air flowing through the dryer,  allowing the refrigeration system to turn off during periods of low  demand without degrading air quality.
The new D-EC dryers offer many features that are not typically  available on small capacity models. The patented, multi-layer heat  exchanger combines the chiller, evaporator and pre-cooler/reheater to  optimize the efficiency of the dryer and compressed air system. In  addition, the precooler/reheater exchanger warms the air exiting the  dryer, thereby eliminating the potential for ambient moisture to  condense on the outer surface of the downstream piping.
A timer-based solenoid drain is installed on the D-EC dryers to  automatically empty moisture from the dryer at regular intervals. Air  temperatures affect the amount of moisture in a compressed air system;  users can adjust the timer to empty more frequently during the summer  when there is more humidity in the air.
The D-EC dryer is configured to minimize pressure drop, which  maximizes the efficiency of the entire compressed air system. The dryer  includes a digital controller that automatically adjusts the airflow and  temperature to keep the system within the parameters defined by the  plant manager. This ensures worry-free operation and extends the dryer’s  usable product life.
 
“Most facilities have varying degrees of compressed air use where  first shift, for example, may have higher demand than second and third  shifts,” explained Christopher Ursillo, marketing manager – air  treatment, Ingersoll Rand. “Non-cycling dryers run at full power  continuously,
while Ingersoll Rand D-EC cycling dryers automatically adjust to the  current compressed air volume. This enables operators to minimize  energy consumption and operating costs.”
The energy-efficient D-EC dryer uses a minimal amount of refrigerant  to cool the compressed air. This maximizes its environmental stability  and helps facilities adhere to sustainable manufacturing practices. The  compact design also minimizes the dryer’s footprint and installation and  shipping costs.
