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
