DRYPOINT® AC 410-495 / HL reliable, innovative and safe

The adsorption dryer from the DRYPOINT AC and the DRYPOINT HL design series guarantee  and stable compressed air supply with increased quality by utilising a high-quality desiccant. The desiccant removes the compressed air humidity down to a pressure dew point of -40 °C, optionally down to -70 °C. This ensures smooth, trouble-free economical production processes.

The Pressure dew point control system and the compressor-simultaneous control system utilise the energy-saving potential particularly efficiently and reduce the operating costs considerably.

The innovative shuttle valve of DRYPOINT AC 410-495 with an internal purge air line allows for adequate purge air flow even in the event of a power failure, making the system „fail safe“. Sturdy galvanised press fittings, easy transport by means of a lift truck and access to all system components show that the unit has been designed with practicability in mind.

The combination of integrated CLEARPOINT upstream and downstream filters as well as BEKOMAT condensate drain off, in conjunction with the simple and intuitive operation, guarantee increased operating safety, not only with DRYPOINT AC but also with DRYPOINT HL.

 

DRYPOINT AC 410

Operating principle of the DRYPOINT® AC / HL

The cold-regenerated DRYPOINT AC adsorption dryer guarantees a continuous supply of qualitative high-quality compressed air. Two vessels filled with desiccant (3) are arranged in parallel. The compressed air is routed through the CLEAR POINT upstream filter and the BEKOMAT condensate drain off (1), which remove particles and condensate from the compressed air as well as the lower switching valve (2) and into the adsorption vessel (3). It is then dried there to the required degree of dryness (pressure dew point). It subsequently flows through the upper switching valve (4) and a CLEARPOINT downstream filter (5), in which any possible resulting abrasion from the desiccant is retained. The dried and purified air is now available for use. While the compressed air is dried in one vessel, the regeneration of the adsorption agent takes place in the other. For this purpose, a partial flow of already dried air is relieved via a nozzle (6) to atmosphere pressure and routed through the desiccant bed for regeneration before it is subsequently released through a silencer (7) into the atmosphere. The switch over between both containers is executed as time-dependent in a specified cycle, optionally also as dew point-dependent. The dew point measured value can, of course, be transferred on optionally to a data logger such as the METPOINT BDL.

DRYPOINT® AC HP high pressure dryer 100-350 bar

When working under high pressure, the requirements for safety and reliability for a system are particularly high. The enormous pressures involved mean that the compressed air is considerably more contaminated by solid particles, oil shares and condensate. The DRYPOINT AC HP adsorption dryer is the linchpin in a performance-capable and safe high-pressure system. It not only removes moisture but also contamination reliably and economically from the compressed air.

Efficiency, quality and service for high-pressure drying

The DRYPOINT AC HP dryer is equipped with a compressor synchronisation control system as standard. The intelligent control system automatically saves the respective status of the process programme. The programme will be continued from the point at which it was interrupted with a restart. This therefore prevents an overload for adsorption desiccant. Operational safety and energy-saving coupling to the compressor operation are the advantages of this solution.

A highly effective calming space with separator and storage function is located at the inlet to the desiccant container. This ensures that condensate is kept away from the desiccant, bound together and transported away during regeneration.

DRYPOINT AC HP

Exceptional solutions for exceptional requirements

  1. The adsorption vessels are made in profiled stainless steel and have a large opening with a screw lid. This makes maintenance easy and even allows for proper inspections of the vessel inside..
  2. The high-performance stainless-steel filters reliably remove solids and oil..
  3. Pressurised components are made in stainless steel as standard..
  4. Two separate pressure reducers for control and regeneration air respectively ensure reliable operation at all times.
  5. The low pressure section is protected by a safety valve..
  6. The control and regeneration air is drawn off behind the afterfilter, ensuring extra reliability and accurate control..
  7. The DRYPOINT AC HP is equipped with a number of individual valve units. Their separate fixtures ensure that there is no extra load on the pipes and also protect the dryer against vibration. This enhances the operational safety of the dryer and reduces maintenance and spare parts costs.

Thanks to the compact design, the dryer fits into virtually any plant.
