• 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
• Stainless steel vessels, support screens and air diffusers
• Furnished in cabinet for easy wall mounting

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
• Automatic operation for reliability and long desiccant life.
• Allows off-stream tower to fully repressurize before going on-stream…prevents bed movement and loss of pressure downstream

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)

Stainless steel vessels, support screens and air diffusers (top and bottom of vessels)
• Easily removed for cleaning
• Filters out gross contaminants…protects valves
• Prevents channeling
• Maximum corrosion resistance

Furnished in cabinet for easy wall mounting
• Completely assembled, piped and wired
• Shipped with full charge of desiccant
• Only hook-up of utilities is needed to operate
