DRYTECH ENGINEERS

We the team of 'Pneumatic engineers, from "Drytech" offers RD Series refrigerated drying unit can deliver the compressed air with quality of air as per ISO specification recommended to various applications.

Exessive leakages in compressed air piping ! Sluggish pneumatic tools / machines operation !! Malfunctioning of precious pneumatic instruments !!! Etc.

Are unlimited problems faced by compressed air users in industries. The root cause of these problems is moisture, oil and dust particles in compressed air.

We the team of 'Pneumatic engineers, from "Drytech" offers RD Series refrigerated drying unit (RDU). the RDU can deliver the compressed air with quality of air as per ISO specification recommended to various applications.



Salient Features

  • Compact and Suitable for indian atmospheric conditions.
  • Complete dryer operation overview through front panel display.
  • Inlet / outlet digital Compressed air temp indication as an option.
  • Least pressure drop.
  • Adopted enviorment friendly refrigerant system.
  • Reliable, automatic drain valve with by pass arrangement.
  • Compact design with maintenance friendly work man ship.

Operation

We Compressed air enters into Compact, highly, efficient corrugated fin & tube 3 in 1 type heat exchanger, where Compressed air is cooled by refrigerant cycle upto +30c. At this temperature moisture from gasious form to into liguid form and separates by in-built moisture separator. This condensate will be effectively removed by automatic drain valve, further air is filtered by fine filter combination and dry air is delivered to down application.
