Jul 14, 2016 · A heat of compression dryer is a type of regenerative desiccant dryer. These machines dry air through adsorption, a chemical process in which a highly porous material attracts and holds on to surrounding water molecules, effectively removing moisture from the air.

By removing moisture from compressed air with a pressure dewpoint as low as -45°C/-49°F, MD, MDG and ND heat-of-compression rotary drum dryers eliminate system failures, production downtime and costly repairs. Atlas Copco's proven rotary drum technology ensures maximum reliable process continuity thanks to the use of high-quality materials.

All desiccant dryers regenerate the wet bed by creating low RH purge air to remove the water vapor on the surface of the beads. A common way of doing this is to add heat to increase the RH differential. This is called “heated type” – one heated type …

The result of nearly 10 years of development work by Henderson Engineering Co., Inc., the SAHARA-PAK heat-of-compression air dryer is considered by many industry observers to be the most significant development ever made in the design of equipment for drying compressed air.

Heat-of-compression (HOC) dryers feature dual-tower, desiccant design technology with the most energy-efficient design available for oil-free applications. HOC dryers recover heat that is a natural by-product of the compression process to offset virtually all electricity costs other than operating the controller -- the cost of powering a light ...

Feb 15, 2018 · What are heat of compression dryers? Heat of compression dryers are regenerative desiccant dryers that use the heat generated during compression in an oil-free compressor to accomplish desiccant regeneration. What are the different types of heat of compression dryers?

Energy Conservation by Heat of Compression type compressed air dryer is a breakthrough in compressed air drying technology. The hot air from the oil-free air Compressor at 120°C or higher temp, is used directly for regeneration of the desiccant bed in the compressed air dryer.

The Heat Compression Air Dryer is designed to take advantage of the natural tendency to desiccant to established equilibrium with their surroundings and can deliver super dry compressed air. These types of Dryers are the most economical …

Jun 25, 2012 · When considering waste heat for a compressed air dryer, the most obvious available waste heat source is the compressor’s heat of compression (HOC) but waste heat can be from any source. Many waste heat designs have been devised in the quest to reduce the high cost of compressed air and provide a more energy efficient total air system.

Why Heat of Compression? The DHC Series heat of compression desiccant air dryers from Gardner Denver provide an energy efficient solution to remove moisture from compressed air. Thermal energy generated during the air compression process of the compressor is utilized to regenerate the offline desiccant tower.
