Manufacturer: Van Air Systems

HB Series Heated Desiccant Dryers 350 through 10,000 SCFM

  • Rated Flow (SCFM) : 10000
  • Dimensions (in.) Height x Width x Depth : Contact ACS
  • Heater (kW) : Contact ACS
  • Blower HP : Contact ACS
  • In/Out Conn.(FLG) : Contact ACS

    * For total desiccant weight, multiply by two. Desiccant is installed on HB 350 and 500 units and shipped separately on larger units. Due to our policy of continuous improvement, dimensions and specifications may change without notice. Request certified drawing for pre-piping. Contact ACS for larger or special models.

    RATED FLOWS BASED ON 100 PSIG, 100F INLET AND 100% RH. CONSULT ACS FOR OTHER CONDITIONS.

Main Features

Van Air HB Series blower purge regenerative compressed air dryers process large volumes of compressed air economically since no compressed air is required to regenerate the desiccant. An externally mounted blower and heater drive hot atmospheric purge air through the desiccant in the offstream tower. A -40F/C pressure dew point protects critical equipment and processes.

All Van Air HB Series dryers feature...

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 always 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.

Operation

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 NEMA cycle includes four hours of drying, three hours of heating and one hour of cooling per tower.

Dew Point Demand Switching

Holds the drying tower on stream until the desiccant bed is fully saturated. At this point, the moisture sensor signals the dryer controls to switch the process flow to the dry tower and regenerate the wet tower. Includes indicator light for in-tower high dew point with dry contacts for remote indication.

Energy Saver

Reduces the heating cycle to match actual moisture loading conditions for operation under low flow or low inlet moisture loading conditions, thus lowering operating costs. A thermostat registers a rise in purge air outlet temperature, which indicates the bed is regenerated, so the heater is turned off. The relay is automatically reset at the end of the cycle.

High Dew Point Indicator

Light is activated when the outlet dew point is higher than the set point. Includes contacts for alarm or remote indicator.

Filtration Recommendations

Regenerative dryers must have clean, oil-free inlet air!

Lubricated compressors

Dryer must be equipped with coalescing prefilters as shown in our filter brochure. Failure to do so may result in hazardous operating conditions and will void warranty. A high temperature afterfilter is recommended to remove desiccant particles.

Non-lubricated compressors

A coalescing or particulate prefilter is recommended to keep pipe scale and dust from entering the dryer. A high temperature afterfilter is recommended to remove desiccant particles.
