Ingersoll Rand®, a global leader in compressed air and gas systems and services, has introduced its new breakthrough dryer technology, the Subfreezing Dryer.

By incorporating its 146 years of engineering expertise and heritage, Ingersoll Rand has designed a dryer that is the first of its kind. The Subfreezing Dryer is the world’s first dryer that provides -4 degrees Fahrenheit pressure dew point at 70 percent lower energy costs and 40% smaller footprint than that of traditional desiccant dryers. Ingersoll Rand’s new Subfreezing Dryer is compatible with oil-flooded rotary compressors, oil-free rotary compressors, centrifugal compressors and reciprocating compressors.
“The new Subfreezing Dryer achieves class leading air quality, previously only attainable with far costlier drum or desiccant dryer technology. We have developed new technology that provides our customers with high quality, -4 degrees Fahrenheit dew point air, from a high performance regenerative refrigerant dryer in an efficient and economical package,” said Nathan Blasingame, Global Portfolio Leader for Air Treatment and System Components for Compression Technologies and Services at Ingersoll Rand. “This breakthrough technology provides very dry air without wasting energy or purging compressed air; customers have the full capacity of their compressor.”
The Subfreezing Dryer supplies a constant ISO Class 3 -4 degrees Fahrenheit pressure dew point air, regardless of changes in demand or ambient temperatures. This allows customers to dependably meet the compressed air needs of their operation.
“Whether customer’s needs are general purpose, or they are manufacturing critical products such as pharmaceuticals, the Subfreezing Dryer delivers the air quality they need,” Blasingame said. “The high-efficiency, superior operating cost alternative – Ingersoll Rand’s groundbreaking Subfreezing Dryer – provides real customer value.”
The Subfreezing Dryer has a lower total cost of ownership than traditional regenerative desiccant dryers and has an 80% lower maintenance cost than drum dryers. Unlike drum and desiccant dryers, there is no costly periodic desiccant replacement, and with no desiccant required, downstream particulate filtering is not needed.
