The new Ingersoll Rand Heat-of-Compression (HOC) dryers provide constant, moisture-free, high-quality air with almost no energy consumption.

Manufacturing applications like pharmaceutical, food and beverage, chemical and automotive industries that require high quality, oil free and low-moisture compressed air can now increase their uptime, sustainability and efficiency while minimising their total cost of ownership thanks to the new industrial Heat-of-Compression (HOC) desiccant dryers from Ingersoll Rand, states the company. The new dryers work with oil-free rotary and centrifugal compressors providing constant, moisture-free and high quality air with almost no energy consumption.

The new HOC dryers from Ingersoll Rand, a global leader in compressed air and gas systems and services, use heat that is a natural by-product of the compression process and would normally be wasted. Instead, the dryers use it to regenerate the desiccant throughout the drying process, which makes them the most energy-efficient type of desiccant dryer available on the market today, opines the firm.

The dryers feature a dual-tower design using reliable desiccant as the drying agent. They utilise the ‘free heat’ resulting from the compression process to provide moisture-free air, while consuming almost no energy. As with all dual-tower designs, the HOC dryer offers a continuous supply of dry compressed air by switching the towers between desorption and adsorption cycles to constantly regenerate the desiccant. According to the company, this allows the compressed air to be in contact with the absorbent media for longer, versus other technologies in the market, which ensures less dependency on working conditions to deliver the required air quality.

Other features of the new Ingersoll Rand HOC dryers include:

• Airflow of 800-6,000 m3/hr for rotary screw compressors and 3,900-15,300 m3/hr for centrifugal compressors.

• State-of-the-art controller with connectivity capabilities and the ability to be installed with multiple compressors. This allows for maximum flexibility in maintaining performance, as well as monitors the health of the unit without sacrificing the integrity of the compressed air system and minimising downtime.

• Full-flow valves and optimised piping layout, that deliver moisture-free quality air and minimise pressure drop.

• Year-round stable dew points down to negative 40 degrees Celsius and below.

• High temperature coating on wet parts to enhance corrosion resistance and extending dryer life.
