New Energy Efficient HOC Dryers

Ingersoll Rand has presented its new green lineup of heat of compression dryers (HOC), which use an energy efficient method to treat the compressed air.

The new HOC dryers not only offer energy efficiency, but also flexibility and reliability in a low-profile form. Wasted heat is converted into energy by the dryers, concluding in dry, oil free air that costs a fraction of mainstream desiccant dryers.

Clean, dry air is essential for an effective and productive compressed air system.  This high-tech, low energy solution is far less expensive to operate than alternative traditional desiccant dryers without losing out on productivity and efficiency, said Christopher Ursillo, marketing manager for air treatment products at Ingersoll Rand. HOC dryers are a great alternative to traditional desiccant dryers, delivering instrument quality air while making use of waste heat from the air compressor.

In order to quantify the HOC’s energy efficiency, you can compare the estimated cost of operating a traditional 1,000 scfm desiccant dryer operating at 8,700 hours a year at $.10/kWh to a comparable HOC dryer. Totaling up the operating costs of electricity and compressed air for purge requirements, the heatless desiccant dryer costs $24,000 yearly to run, and the blower purge desiccant dryer costs $18,000. In the same conditions, Ingersoll Rand’s HOC dryer costs $120 yearly to operate.

No-loss drains that prohibit the waste of compressed air are just one of the featured components of Ingersoll Rand’s HOC dryers. These drains feature a low-pressure drop design that allows the air compressors to run at a lower pressure, thereby conserving energy. Other unique components of the HOC dryer’s drain include stainless steel heat exchangers that provide optimum performance even in the worst conditions, and guaranteed removal of condensation via its automatic drain bypass feature.

The low profile form of the HOC dryers mean that they can be installed in many areas, including those with low overhead clearance. Ingersoll Rand HOC’s low profile design also allows for service personnel to easily service dryers when necessary. The HOC is unique in its class as it was designed to accommodate the use of multiple compressors, allowing its footprint to be reduced as well as installation costs.
