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. Advantages Limited pressure drop, even in case of extreme load. Extremely constant dew point, also under variable working conditions. Excellent performance, thanks to the counter-flows of air-refrigerant exchanger. Large exchange surface, favoring a correct and complete refrigerant evaporation (avoiding liquid backflow in the compressor). Low maintenance and excellent air drying. MD Series refrigeration dryers have an air flow ranging from 0.6 to 147.2 m3/min and working pressure from a minimum of 7 bar to a maximum of 14 bar. MD dryers are also available in high-pressure versions, through our MDH Series. Compressed air is used in industrial productive processes, as it is a clean and convenient energy source. However, to optimise the efficiency of the system, this important resource needs to be properly treated to assure top efficiency. The ambient air intaken by a compressor always contains the water vapour, the value of which depends on the temperature and the relative humidity degree. When the air is compressed, the volume decreases proportionally but all the exhausted water vapour still remains in the air.Condensate corrodes piping, solenoid valve, pneumatic tooling and the user is then obliged to stand expensive repair interventions; especially the expensive “down times” cannot be controlledvery easily.
