CAB Series - Legendary Blower Purge Drying Technology

Superior Efficiency - Legendary Design

CAB Series dryers use multi-stage centrifugal blowers to deliver 100% inlet-to- outlet compressed air capacity and superior energy efficiency. In regeneration mode, atmospheric air, stored heat absorption and a high efficiency external heater combine to evacuate the collected water vapor. Operating at full, design load conditions, inlet-to-outlet air volume remain constant and -40 degree fahrenheit pressure dew points are produced. CAB Series dryers deliver superior efficiency by design.

Patented Automated Moisture Load Control (AMLOC)

Today's air system auditors know that it is rare to find a dryer that operates under full load conditions. This is why AMLOC is a standard equipment on every CAB Series dryer. AMLOC Energy Management Systems generate ten-of-thousands of dollars in energy saving annuities of industry leaders. It reduces cycle frequency to extend component life and ensures consistent dew points.

Moist filtered compressed air enter down flow drying Chamber 1 via valve (A). Water vapor is absorbed into the desiccant and dry compressed air exits through valve (B) where abrasive desiccant dust is captured by a high temperature after filtered. In regeneration mode, atmospheric air is drawn through a muffler / filter and compressed by a multi-stage centrifugal blower (C). Balanced heat distribution in Chamber 2 comes from a natural heat-of-absorption and an external, low watt density heater (D). Blower discharge flows through the heater, through valve (F) and then through the desiccant and evacuates through valve (E). Once desorbed, the heater and blower turn off and the bed is allowed to cool. Finally valve (E) and (F) close and Chamber 2 is repressurized through valve (G). No further energy will be consumed until AMLOC determines the on-line bed is fully utilized. Whereupon, operations will switch and Chamber 1 will be regenerated.

AMLOC governs this process with precision. Patented capacitance probes senses the dielectric strength water vapor imparts on the desiccant. Low moisture loads extend the drying cycle while eliminating energy use. Fewer flow reversals and minimal thermal stress yields longer desiccant and valve life. Serious performance, reliability and energy savings result consumption mirrors plant air usage.
