FMD - Refrigeration Air Dryers

The new FMD series of refrigeration dryers replaces the “Original” AMD and has been redesigned considering:

• The use of R513A refrigerant gas with very low environmental impact (GWP = 631_CO2 ton/eq);
• An improved dew point at 3°C;
• New compactness ALU-DRY heat exchangers;
• New component layout;
• A new frame design for greater strength.

Symbolised by a four-leaf clover, FMDs have four indispensable features for compressed air treatment.

• Consistent and guaranteed performance over a wide range of temperature use.
• Cost-effectiveness due to their compatibility with the compressor sizes on the market.
• Functionality with user-friendly electronic controllers (INDUSTRY 4.0 ready) for managing condensate drainage and condensation, stainless steel hot gas by-pass valve and ALU-DRY heat exchanger on the entire range.
• Ecology: the materials used are highly recyclable and R513A refrigerant gas comply with current regulations.

MAXIMUM WORKING CONDITIONS

• Ambient temperature: + 45°C
• Air inlet pressure: 16 barg
• Inlet air temperature: + 55°C

Data refer to the following nominal conditions: ambient temperature +25°C; air inlet pressure 7 barg; air inlet temperature +35°C; and a pressure dew point of 3°C.
