Mattei's MD Series (direct expansion) and EMD 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 aluminum ultra-compact drying module for compressed air treatment. Aluminum guarantees high resistance to corrosion, excellent thermal conductibility and mechanical resistance, together with a high level of recyclability.

MD dryers are also available in high pressure version (MDH).
