Arrow Pneumatic Dryers

Arrow Blower Purge Dryers

Arrow's "BP" series blower purge regenerative dryers are more 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 only for plant operations.
Standard Features:
• Fully automatic to provide the most efficient operation
• Panel mounted Gauges to monitor pressure
• Indicator Lights that display tower operating status
• Reliable pneumatic valve operation
• Controlled repressurization to eliminate line surges and desiccant attrition.
• Removable stainless steel diffuser screens
• Nema 4 electrical construction
• Universally accepted 120V/1ph/60Hz
• Power on indicator to show dryer status
• Tower relief valves to prevent overpressurization.
• ASME coded and stamped pressure vessels.
• Microprocessor controls or PLC for controls.
• Control air line filter with replaceable element to protect pneumatic circuitry.
• Exhaust purge muffler for quiet operation
• Pressure alarm package that indicates failure to shift, failure to depressurize, failure to repressurize and failure to purge.
• Heater Thermostat to control and maintain user adjusted regeneration temperature to account for changing flow or seasonal moisture variations.
• Interlock circuit to protect units from heater burnout due to loss of purge air flow.
