Refrigeration Dryers

MD Series (direct expansion) and HTMD Series (thermal mass) refrigeration dryers are based on the principle of condensation by compressed air cooling, through a refrigeration circuit. The dryers are available in both the stand-alone version and integrated in the compressor. Mattei’s MD Series dryers use an aluminium ultra-compact drying module for compressed air treatment. Aluminium guarantees high resistance to corrosion, excellent thermal conductibility and mechanical resistance, together with a high level of recyclability.
 

ADVANTAGES

  • Limited pressure drop, even in case of extreme load
  • Extremely constant dewpoint also under variable working conditions
  • Excellent performances, thanks to the counter-flows of air-refrigerant exchanger  
  • Large exchange surface, favouring a correct and complete refrigerant evaporation (avoiding liquid backflow in the compressor)
  • Low maintenance and excellent air drying


MD refrigeration dryers have air flow ranging from 0.6 to 147.2 m3/min and working pressure from a minimum of 7 to a maximum of 14 bar. HTMD Series air flows range from 0.5 to 17 m3/min and working pressure from 7 to 16 bar.
According to environmental protection regulations Mattei uses recyclable materials and low GWP (Global Warming Potential) refrigerants for its dryers.


Both solutions are ideal for various kinds of applications, such as the mechanical, graphics, food, chemical, textile industry; for pneumatic cylinders and coating plants.
