DE iTech 

Energy saving refrigerated air dryers

Air flow 0,4 – 37,7 m³/min

DE iTECH  is the new generation of energy saving refrigeration cycle dryers with which MTA not only renews its range of products for the processing of compressed air but reinterprets the concept of thermal mass to which the DE Hybrid dryers owe their success. The innovative Impulse Technology system offers important advantages in terms of energy savings, reliability and management costs thanks to the ability of DE iTECH to adapt perfectly to the real requirements of the system. The dryer adjustment system controls its operation and ensures the ideal energy solution for drying of the compressed air, allowing high savings and at the same time excellent stability of the dew point, even under dynamic conditions.

  • Innovative Impulse Technology system for control of the drying capacity via impulse adjustment of the refrigerant liquid flow or due to the thermal mass effect;
  • Compact 3-in-1 aluminium heat exchanger with optimised perfect countercurrent heat exchange, it contains a stainless steel condensate separator;
  • Minimal load losses (average 0.09 bar) through fluid dynamic optimisation and the large transfer sections;
  • Constant dew point under every operating condition;
  • Low environmental impact and reduced carbon dioxide emissions thanks to the Impulse Technology energy saving system and the use of R134a and R410A environmentally friendly refrigerants; 
  • Dual frequency power supply for models 101-165-190-230-270-320;
  • UL508A version: power supply 115V/1/60Hz, 230V/1/60Hz, 230V/3/60Hz, 460V/3/60Hz, depending on model;
  • Quick and easy installation;
  • Simplified maintenance;
  • Maximum reliability.
