BOGE -Adsorption Dryers

 

DAV Series
Externally heated regeneration with vacuum drying, complete with pre-filter and after-filter

Vacuum regenerated adsorption drying is the energy efficient solution for higher volumes of compressed air. Dewpoints to -70°C are possible!

 

 

Before entering the dryer, a BOGE ‘F’ series micro-filter removes solids and impurities from the compressed air to 0.01 mg/m3. In the drying tower, the desiccant media removes moisture from the air to a dewpoint of -40°C (standard models).

 

The parallel tower regenerates the wet desiccant bed. First it de-pressurises to atmosphere, simultaneously the vacuum pump begins to draw ambient air, that is pre-heated on entry, through the wet desiccant to complete the regeneration process.

 

The advantages of using the BOGE DAV Adsorption Dryer

 

• Energy efficient system
  Savings of up to 25% compared to conventional systems

• 2-stage drying
  Optimised flow distribution through media bed
  Self cleaning media reduces Δp and increases moisture separation

• Low regeneration temperature
  Vacuum regeneration ensures energy efficient moisture removal at lower temperatures than traditional heat regeneration

• Vacuum cooling
  After drying the media the heater switches off and the vacuum pump sucks ambient air through the bed to cool it

• Pressure equalisation on wet side
  Regeneration takes place at atmospheric pressure. Venting tower is therefore total purge loss

• Consistent pressure dewpoint in operation
  Because ambient air drawn in from the drying process

• Constant pressure dewpoint at changeover
  Because compressed air re-pressurises dry tower

• Pressure dewpoints to -70 °C
  Possible as well as the standard -25°C or -40°C

• Function display
  For pressure, temperature, heater operation, vacuum pump and changeover

• Alternative energy
  Regeneration using steam, hot water and other is available as an option

• Modular options:
  Purge air by-pass, thermistor controlled heaters, frequency controlled vacuum pumps
