SPX Hankison Descicant Air Dryers

Consistent Outlet Pressure Dew Points: Industry-Leading Desiccant Beds

Premium grace desiccant beads offer enhanced surface area and high crush strength vhidi prolongs bed life

Large desiccant beds ensure 4.8 seconds of contact time…allows wet, saturated air at the dyer inlet to be dried to the required dew point

30% extra desiccant provided to compensate for natural bed aging…ensures top performance over expected 3 to 5 years of desiccant bed life

Large flow diffuses ensure even flow distribution through the bed and eliminate channeling

Towers are sired so that air velocity through he bed won’t fluidize the desiccant which prevents bed movement and desiccant dusting

Up-flow drying a loins water and heavy contaminants to drop out of the air stream as they enter a tower which Protects the bed from contamination. This makes it simple to discharge he contaminants when the tower depressurizes.

Cleanable stainless steel how diffuses / support screens and separate fill and drain ports for ease of desiccant replacement

Slash Purge Air Energy Costs

Since 1948, compressed air users have relied on Hankison to provide compressed air treatment products with integrity. Global demand for Air Quality Class 3 and our advanced Ambient Air Amplification (A3) Purge Technology'” wades us to offer you externally heated purge desiccant dryers with dew mint performance guaranteed tom 8.5 to 90.6 Nm3/min.

Standard HPD Series Dryers —20°C to —40°C Pressure Dew Points

Designed for applicantions that were previously forced to accept a -40°C pressure dew point when simple protection against seasonal freezing is the issue. The standard design delivers ISO 8573.1 dew points between Class 2 and Claw 3 automatically. Class 2 (-40°C) dew mints protect against freezing during low ambient conditions and Class 3 (-20°C) dew mints keep your air system bone dry during the heat of summer. applications that require Class 2 (-40°C) dew points year round simply need to select the Free-Air (FA) Supercharger option package.

PROTECTS AIR SYSTEMS EXPOSED TO TEMPERATURES BELOW FREEZING

Produces pressure dew point of -40°C

Fully Enclosed Wall-mounted Package delivers dew points of ISO 8573.1 Class 2 (-40°C, -40°F). Labs, Hospitals, and Hi-Tech installations all benefit with dry air and more floor space.

  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

Moisture can be a real problem in a compressed air system. The air outlet temperature of a compressor / after-cooler package is typically 25-50C and saturated with water vapor, which results in significant amounts of liquid downstream. The moisture in a compressed air system can cause serious problems ranging from products spoilage to equipment malfunction, thus making an air dryer is a critical component in any compressed air system.

Our HDB series compressed air dryer reduces the concentration of water vapor and decreases the pressure dew point of the air to -40C (Optional: -73C)

HDB compressed air dryers use porous materials (desiccants) to adsorb moisture from the compressed air. For regeneration, heated ambient air is used instead of expensive purge air to desorb moisture from the regenerating bed. No purge loss means DRYER-IN is almost same as DRYER-OUT.

• Minimize the dew point spike during tower change
• Stable -40C PDP (Optional -73C PDP)

Energy saving
