Regenerative Dryers have been specially designed to provide compressed air pressure dew points down to -40 through -100 degrees F lower than the compressed air temperature entering the dryer when operating at rated conditions.

Performance and Specifications Models available, Air Flow from 10 to 12000 SCFM.

REGENERATIVE HEATLESS DRYERS
Twin tower regenerative dryers are the dryers of choice when  traditional refrigerated dryers do not provide sufficient air quality required for today's applications.  Arrow's reliable "RH" series of heatless twin tower regenerative dryers normally produce a -40ºF and can optionally be as low as -100ºF dew point.  The dryer utilizes activated alumina for efficient drying of compressed air and will operate under extreme environmental conditions.  Activated alumina is aluminum oxide that is highly porous and exhibits tremendous surface area (350 sq. meters/gram).  It has a smooth uniform ball size that prevents channeling of the air flow, which maintains low bed velocities.  This maintains air contact time for efficient moisture removal and minimal pressure drop.  Arrow's microprocessor dryer controls are housed in a NEMA4 rated enclosure and provide control of pneumatically piloted valves chosen for long life and high air flow.

Externally Heated Regenerative Dryers

Arrow Pneumatics heatless and heated regenerative dryers are energy efficient with state-of-the-art humidity control and also offer a wide range of options to suit any need.

EXTERNALLY HEATED REGENERATIVE DRYERS

The Arrow Pneumatics externally heated twin tower regenerative dryers combine the high reliability of our "RH" series desiccant dryer and adds external heaters to form the "RE" series dryer.  Dew points, normally -40ºF can optionally be as low as -100ºF.  Purge air is approximately 7% of rated flow, thus reducing the operating costs of the heated twin tower regenerative dryers compared to the heatless regenerative dryers.  Purge air in the "RE" series is heated by a 100% efficient incoloy sheath electric heater allowing long life and energy savings.  The heater and purge piping are insulated for safety and further energy savings.  Arrow "RE" series heated dryers have microprocessor controls housed in a NEMA4 rated enclosure.  Pneumatically actuated valves have been chosen for long life and high air flow.

Arrow Pneumatics "BP" series blower purge regenerative dryers are made economical to operate than heated or heatless regenerative dryers.  An external blower supplies heated atmospheric air as the purge air source for regeneration.  
This allows total air compressor capacity for plant operations.  Eliminating the use of compressed air as purge allows the plant to more economically size the compressor for only plant operations. The blower purge offers the same easy maintenance features found in our heated regenerative dryer.  The blower is designed for industrial applications and has an intake filter that protects the blower and dryer from damaging air born particles.
