SPX Hankison Descicant Air Dryers HEA Series

PROTECTS AIR SYSTEMS EXPOSED TO TEMPERATURES BELOW FREEZING

Produces pressure dew point of -40°C

Delivers dew points of ISO 8573.1 Class 2 (-40°C, -40°F). Labs, Hospitals, Hi-Tech, and Light Industrial installations all benefit with dry air and more floor space.

• Flow rates from 1.5 Nm3/min to 17.3 Nm3/min (55 to 600 scfm)
• Highly accurate solid state timer
• Front mounted control panel
• Clean, streamlined piping and utility connections simplify installation
• Automatic operation and stored absorptive energy result in long desiccant life
• HK Series coalescing filter packages available
• ASME steel vessels, support screens and air diffusers

FEATURES

• Consistent outlet pressure dew points – large desiccant beds produce -40°C (-40°F) pressure dew point [equals an atmospheric dew point of -57°C (-71 °F)]
• Minimum purge air usage – saving the heat of adsorption maximizes the moisture holding capacity of the purge air, minimizing the amount required
• Long desiccant life – beds sized to prevent fluidization plus slow and complete regeneration prevent desiccant movement and deterioration
• Heavy duty purge exhaust muffler for quiet operation
• Non-lubricated, soft seated control valves

Highly accurate solid state timer

• Provides increased desiccant life over units operating on shorter cycles
• Allows off-stream tower to fully repressurize before going on-stream…prevents bed movement and loss of pressure downstream

Accurate and durable process valves

• Inlet/outlet shuttle valves automatically shift to the low pressure side of the circuit to control process flow
• Shuttle valve life tested to >500,000 cycles
• Purge/repressurization valves are normally closed, pneumatic piston actuated y-angle poppet valves or direct acting solenoid valve.

Front mounted control panel

• Power on light
• Lighted on-off switch
• Active tower indicator lights

HK Series coalescing filter packages

• Type H oil removal prefilter to 0.01 micron
• Type D dry desiccant afterfilter (1 micron)

ASME code vessels, support screens and air diffusers

(top and bottom of vessels)

• Easily removed for cleaning
• Filters out gross contaminants…protects valves
• Prevents channeling
• Completely assembled, piped and wired
• Shipped with full charge of desiccant
• Only hook-up of utilities is needed to operate
