DDCY - Bi-directional flow and anti-acid filter driers


Technical description
• Refrigerant filtering, drying and acid neutralization for refrigerating and air conditioning installation liquid lines with change over in flow direction, including heat pumps.
DDCY - Bi-directional flow and anti-acid filter driers
CARLY advantages
  • Maximal working pressure: 46 bar. 
  • Two-way filter drier with very low pressure loss thanks to a CARLY patented internal check valve system ensuring an optimum circuiting of the flows. 
  • No risk of discharge of the pollutants trapped inside the filter driers, during change over in flow directions.
  • 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. 
  • Filter driers sizes that ensure interchangeability with most products of the market. 
  • 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 up to a diameter of 3/4’’ - 18 mm facilitate the brazing and allow using brazing alloys with a low silver percentage.
