Refrigeration Dryers

Air flow 0,35 – 35 m³/min

DE-X refrigeration dryers offer accurate dew point control in an easy-to-use package with very wide operating parameters and a strong focus on reducing overall global impacts. Unique features and patented technologies ensure the requirements of individual industrial applications are fully catered for.


  • Market leading pressure drops, on average below 0,12 bar, ensuring significant energy savings.
  • Environmentally friendly low Global Warming Potential (GWP) refrigerant R513A on DE-X 003-090, with a GWP of only 573.
  • Unique patented 3-in-1 X-MODULE heat exchanger, designed by MTA.
  • Always operates in all conditions, with extensive air inlet temperature, ambient temperature and maximum pressure limits.
  • High reliability, with field proven technologies and premium components.
  • Easy to install thanks to compact dimensions, a single wired power source and full frontal access.
  • Easy to use: intuitive microprocessor, avoids field adjustment requirements, low maintenance needs.
  • Multiple condensate drain configurations covering every User need.
  • Accurate dew point control across the full 0-100% load spectrum, with quick reactions in response to sudden peaks.
  • Low Load Function (LLF) protects against freezing, simplifies seasonal adjustment needs, allows stand-by savings at low ambient temperatures.
  • Industry 4.0 ready, with multiple remote connectivity options.
  • Extensive individual factory testing (operating sequences, refrigerant leakages, safety devices, electrical safety).
