Heat-Of-Compression Air Dryer

Heat-of-compression (HOC) dryers are dual-tower, desiccant designs. The HOC dryer is the most energy-efficient dryer available. It recovers the heat that is a natural by-product of the compression process. This “free” heat is utilized in the air-drying process to provide moisture-free air while consuming virtually no energy.


Reliability
Ingersoll Rand heat-of-compression (HOC) dryers, HC-Series, are the world’s simplest and most reliable regenerative dryers. Their design innovation, coupled with unsurpassed performance, will help assure the reliability of your compressed air system.

  • High Performance: HOC dryer includes proven highperformance two-way valves, providing years of troublefree operation. 
  • Unique Design: Unique design of the HOC dryer with its stripping and cooling cycles, enables it to achieve year-round dew points below -40°C.
  • Smart PLC based control system: Equipped with PLC based control system that maintains performance and monitors the health of unit, so downtime can be minimized. 
  • Expansion Flexibility: HC Series Dryers can be installed with multiple compressors, allowing maximum flexibility without sacrificing the integrity of the compressed air system.

Energy Efficiency 

Heat-of-compression dryers are the most cost-effective means to protect air lines, tools and expensive instrumentation. 

  • Reduced Electrical Cost: The HC series has a very reduced total electrical cost as they use very small strip heaters of neglible capacity.
  • Compressed Air Saving: The HC series design consumes neglible purge air
  • Minimum Pressure Drop: The HOC dryer is designed to minimize pressure drop by utilizing full-flow valves and minimal piping. 

Consistent Dew Point 

The HC-Series can constantly provide -40°C or lower dew points, at a fraction of the cost associated with other regenerative type dryers
