Sub-Freezing Air Dryer with breakthrough refrigeration technology

26 February, 2018

By incorporating its 146 years of engineering knowhow, Ingersoll Rand has designed a dryer that is claimed by the company to be the first of its kind. The Sub-Freezing Dryer is said to provide -20degC (-4degF) pressure dew point at 70% lower energy costs and 40% smaller footprint than traditional desiccant dryers. The Sub-Freezing Air Dryer is compatible with oil-flooded rotary compressors, oil-free rotary compressors, centrifugal compressors and reciprocating compressors.

Rolf Paeper, vice president of product management and marketing for compression technologies and services at Ingersoll Rand, commented. “The new Sub-Freezing Air 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, -20degC dew point air, from a high performance regenerative refrigerant dryer in an efficient and economical package. This breakthrough technology provides very dry air without wasting energy or purging compressed air; customers have the full capacity of their compressor.”

He continued: “Whether customers’ needs are general purpose or they are manufacturing critical products such as pharmaceuticals, the Sub-Freezing Air Dryer delivers the air quality they need. The high-efficiency, superior operating cost alternative – Ingersoll Rand’s groundbreaking Sub-Freezing Dryer – provides real customer value.”

The Sub-Freezing Dryer is claimed to have a lower total cost of ownership than traditional regenerative desiccant dryers, and 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.
