Reheat Systems


The traditional methods of drying compressed air can be expensive to operate and maintain. A typical arrangement includes an aftercooler and a refrigerated dryer. In this arrangement up to twenty percent of the total compressed air energy can be lost when the air is cooled to condense and remove moisture in the stream. As a result, many plants are turning to the Reheat System from R.P. Adams.

 ADAMS Reheat Systems are custom packages specifically designed to add energy back into your compressed air system. This package is unique in the industry, utilizing the heat of compression to recover the lost gas volume and deliver clean, dry air without the need for an external energy source. Therefore, free heat is being provided to your compressed air proces. The system is efficient enough to take the place of a refrigerated dryer, depending upon pressure dew point required and coolant available. Typical dew points achieved range from 37°F to 90°F. The system also reheats the compressed air to temperatures desired for your process.

(arranged as shown above).


How does it work?





  • Cooling the air
  • Moisture removal
  • Reheat the air



Adams Reheat systems come in a variety of configurations. The Economat / Reheat System is used with a single or multiple cooling water source. When a refrigerant is available at the plant, such a ammonia refrigeration in a food processing facility, then the AKU Reheat System is recommended. (Reheat Bulletin for more details)

 Factors Effecting a Reheat System Design:

  • Air flow rate
  • Final dew point temperature desired
  • Final air temperature desired after it is reheated
  • Air pressure drop allowed through the system
  • Types of coolant available

Benefits of a Reheat System

  • Provides a gas dew point between 35°F and 90°F
  • Offers dry, high temperature air for production or process
  • More economical than a refrigerated dryer
  • Minimal space required for installation
  • Dry, high temperature air ranging from 90°F to 300°F for your process
  • Produces more air volume for the same power consumption
  • Conserves cooling water -- the reheat unit pre-cools the air prior to the Aftercooler, thereby reducing the cooling load on the aftercooler
  • No external power costs to reheat the air
  • Virtually maintenance-free with no moving parts or control mechanisms requiring annual labor
  • Elimination of condensate in the air distribution system and external line sweating
  • No moving part making it virtually maintenance free
