Aircel AHLD E-Series - Features & Options

AHLD Series | Heatless Regenerative Desiccant Air Dryer
10
FEATURES & OPTIONS
Standard Features
• Integrated Energy Management Purge Reduction System for ecient energy savings and reduced cost of operation.
• Optimal tower size for low velocities reducing desiccant uidization, and high contact time for ecient low dew point
performance.
• Tower pressure relief valves.
• Standard design capacity based on 100 psig, 100°F inlet air, 100°F ambient air, and Pressure dew point of -40°F.
• Purge exhaust muers for quiet operation.
• Tower pressure gauges for additional visual operation of dryer operation.
• Stainless steel desiccant supports and air diusers to prevent channeling.
• Counter-current reactivation for ecient desiccant regeneration.
• PLC Controlled Electrical System
• Adjustable (5 min., 10 min.) cycle times: 10 minute cycle for the standard -40°F Pressure dew point outlett dew point
systems, 5 minute cycle used in the optional -100°F Pressure dew point outlet dew point systems.
• Controlled repressurization to slowly repressurize the regenerated vessel to line pressure prior to switch over preventing
desiccant bed movement and attrition.
• Fail safe design: Failure of power and/or pilot air causes the purge exhaust valves to close, eliminating loss of air pressure.
The system also provides uninterrupted drying air ow, preventing a deadheading aect.
• Control pilot air lter provides clean air to air control system for long trouble-free reliable operation.
• Desiccant towers are designed, fabricated, and stamped according to ASME code.
• Desiccant ll and drain ports for ease of desiccant replacement.
• Structural steel frame.
• Highly reliable non-lubricated air inlet and outlet valves (APV) Automatic Piston Valve (AHLD 70 E - AHLD 750 E) and high
performance, non-lubricated buttery valves (AHLD-1000 E - AHLD-1500 E).
• Highly reliable angle seat design purge exhaust valves.
• Tower operating LED status lights (left and right tower dryer, left and right tower regenerating).
• On/O switch and power On light.
• NEMA 4 weather resistant electrical system construction.
Additional Options
• -100°F outlet pressure dew point.
• Failure-to-shift alarm with pressure transducers.
• Outlet dew point sensor with dew point readout on system display.
• High humidity alarm.
• Outlet dew point 4-20 ma signal.
• Mounted, piped, and wired ltration packages.
