Anti-acid filter driers DCY-P6 / 64 bar

  • Model DCY-P6 for 64 bar (928 psig)
  • CO2 subcritical
  • Hermetically sealed outer steel enclosure with paint to ensure a high resistance to corrosion


Filtering and drying of refrigerants and acid neutralization for liquid lines of refrigerating and air conditioning installations, running with high working pressures.

Technical specifications

  • Products are compatible with HFC and CO2, as well as with their associated oils and additives
  • Products are designed for use of non-hazardous refrigerants from group 2 of PED 97/23/EC
  • Product classification in CE categories is done with the PED 97/23/EC table, corresponding to a volume-based selection
  • Hermetically sealed outer steel enclosure with paint to ensure a high resistance to corrosion
  • Filtering at outlet preventing propagation within the circuit of particles bigger than 25 microns, with a very low pressure drop
  • No desorption, even at a high temperature

Several types of connections are possible on standard products:

  • To be screwed type SAE
  • To be brazed for tubes in inches (S)
  • To be brazed for tubes in millimeters (MMS)


  • Max working pressure: up to 64 bar with CO2 in subcritical compression systems
  • Great drying and acid neutralization capacity at all temperatures, thanks to a rigorous selection and a judicious mix of the chemical agents present in the filter driers (activated alumina in order to neutralise the acids and molecular sieves to adsorb moisture); the volume of free-grains drying agents used in a CARLY filter drier is greater than that present in an equivalent model with a solid core
  • Initial drying capacity guaranteed by a 200°C oven drying and airtight sealing
  • Drying ensured for the subcritical CO2 applications at low temperatures
  • A dispenser located at the inlet ensures optimal distribution and permanent treatment of the whole refrigerant, inside the filter drier
  • The copper-plated steel connections facilitate the brazing and
  • allow using brazing alloys with a low silver percentage
  • Installation possible in all positions


  • Refrigeration and air conditioning
