TWP Series Externally Heated Desiccant Air Dryers
Replaced by NextGen TWP Series
A Parker Airtek TWP Series Externally Heated Desiccant Air Dryer will effectively remove contaminants such as dirt, water, and oil. The traditional adsorption principle used in this design is simple, robust and flexible. Continuous drying is accomplished by the operation of two desiccant towers.
Pressure dewpoint of -40°F (-40°C) and flowrate of 200 – 7500 scfm depending on model.

Compressed air is polluted with dirt particles, water, oil, oil vapor, and condensate. These contaminants result in high maintenance costs, premature wear, spoiled products and the failure of control systems. Compressed air is dried through one tower while the other desiccant tower is being regenerated. The regeneration heating cycle of desiccant is accomplished using a dry air purge flow heated by an external electric heater. The regeneration cooling cycle is performed using the same flow of dry compressed air taken from the desiccant air dryer outlet to ensure continuous dewpoint performance.
Features & Benefits of Parker Airtek TW Series Air Dryers:
• Flow rate starting at 200 scfm (340 m3/hr)
