Van
Air HB Series heated regenerative compressed air dryers are
designed to protect pneumatic equipment and processes from
the harmful effects of moisture within compressed air lines.
When you don't have compressed air to spare, Van Air HB Series
air dryers provide the solution requiring no purge air for
adsorbent desiccant regeneration.
Van
Air HB Series heated regenerative air dryers are able to
process large volumes of compressed air both economically
and efficiently. Unlike a heatless regenerative air dryer,
Van Air HB Series air dryers require no compressed air to
regenerate the desiccant. Instead, our HB Series air dryers
utilize an externally mounted heater and centrifugal blower
to drive hot atmospheric purge air through the desiccant
bed to regenerate the adsorbent desiccant.
Wet compressed air is directed downward through the drying
tower where moisture is adsorbed on the desiccant. In the
regenerating tower, moisture is stripped from the desiccant
by atmospheric air drawn in through the blower and passed
over the heater. As the hot purge air flows through the
bed, it collects moisture and is discharged through the
purge valve(s). The eight-hour MENA cycle includes four
hours of drying, three hours or heating and one hour of
cooling per tower.
By using
a Van Air HB Series heated regenerative compressed air dryer,
you are able to dry your compressed air in the most efficient
and cost-effective way. You may even eliminate the need
for an extra air compressor to compensate for purge air
usage. There are significant savings when compared to the
air usage in a heatless or heated purge dryer of the same
size, keeping more air available for your production processes.
Constructed
and tested to the most demanding standards, our HB Series
compressed air dryers are built in-house with quality and
efficiency in mind. All HB Series desiccant vessels are
ASME certified and insulated with an aluminum jacket for
the greatest safety and operating efficiency. The Incoloy
heater is also insulated with an aluminum jacket and is
resistant to high temperatures and corrosion, guaranteeing
a long life. The centrifugal blower contains only one moving
part for minimal vibration and ensures a long operating
life. Standard on all HB Series air dryers, our patented
Interlock valve ensures the most reliable tower cycling.
•
Fully Insulated Towers and Heater
Aluminum jacketed insulation on both towers and heater for
greatest safety and operating efficiency.
•
Centrifugal Blower (3000 scfm & up)
Less vibration, no gears to wear out and only one moving
part for long operating life.
•
Long Heater Life
Incoloy heater resists high temperatures and corrosion.
•
Interlock Logic Valve Control
Patented valve control for the most reliable tower cycling.
Each phase of the drying cycle must be completed before
the next can begin. Protects against loss of flow or pressure
because the offstream tower is fully repressurized before
air flow is redirected to it and a tower can only depressurize
after the inlet transfer valve is fully seated.
•
Failure to Switch/Pressurize Light and Contact
Pressure switches sense offstream tower pressure. Failure
to switch is indicated when inlet valve does not shift or
when tower does not repressurize.
• Polishing Purge Selector
Cools desiccant bed to minimize dew point temperature spikes
at tower changeover.

Filtration Recommendations
Lubricated Compressors - Dryer must
be equipped with proper Van Air pre-filters. These filters
must be drained and maintained as specified. Desiccant
beds should be checked periodically and replaced if
contamination has occurred. Failure to do so may result
in hazardous operating conditions and will void the
warranty. An after-filter should be installed downstream
of the dryer to prevent desiccant particle migration.
Non-lubricated
Compressors - A particulate or coalescing
pre-filter is recommended to prevent pipe scale and
dust from fouling the dryer. An after-filter should
be installed downstream of the dryer to prevent desiccant
particle migration.
