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.

Benefits:

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).
