Blower Purge Heat Reactivated Desiccant Air Dryer -TWB Series

Parker Airtek TWB Series Externally Heated Blower Purge Desiccant Air Dryers use heat and the adsorption method to remove moisture from compressed air. 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.
    Parker Airtek TWB Series Blower Purge Desiccant Air Dryers will effectively remove these contaminants.  The traditional adsorption principle used in this design is simple, robust and flexible using compressed air for regeneration therefore eliminating any need for an outside energy supply.
    Continuous drying is accomplished by the operation of two desiccant towers.  

    Compressed air is dried through one tower while the other desiccant tower is being regenerated.  The regeneration heating cycle of the desiccant is accomplished using a hot air flow delivered by an atmospheric blower and external electric heater (other means of heating are optional).  The regeneration cooling cycle is performed using a small flow of dry compressed air taken from the blower purge dryer outlet to ensure dewpoint performance. High levels of reliability are achieved by the use of proven engineering technology and components.

    • Flow rate starting at 200 scfm (340 m3/hr)
    • Delivered air quality is in accordance with ISO 8573.1: 2001, the international standard for compressed air quality.
    • Pressure dewpoints of -100°F (-70°C) & -40°F (-40°C) (ISO 8573.1: 2001 Classes 1 & 2) are available.
    • Parker Airtek pre- and after compressed air filters - Standard
    • PowerLoc Energy Management System* - Standard
    • Low-wattage high incoloy sheathed heater for efficient regeneration
    • High-efficiency, quiet running regenerative (up to 3000 scfm) or centrifugal blowers (4000 scfm and larger)
    • Parker non-lubricated full-flow angle seat valves, which carry a FIVE YEAR VALVE WARRANTY, are standard on dryers up to 800 scfm.
    • High performance, actuated butterfly switching valves, which carry a FIVE YEAR VALVE WARRANTY, are standard on dryers 1000 scfm and larger.
    • Insulated tower, heater and purge lines increase dryer performance and efficiency by reducing radiant heat loss plus keeps the unit with the safety parameters set forth by OSHA.
    • Easy to use Control Center affords superior dryer control along with digital telemetry for remote analysis of performance.
