Filtering - Drying - Decontamination


Refrigerant filtering and drying, and acid neutralization for refrigerating and air conditioning installation liquid lines.

The filter driers receivers provide a permanent reserve of dehydrated and filtered refrigerant, for a better supply of the expansion valve, whatever the operating conditions.

The filter drier receivers are particularly suited to low capacity installations that operate with a thermostatic pressure relief valve and that are equipped with an air-cooled condenser or a plate condenser.

Filter drier receivers fit perfectly within the heat pump systems.

Carly advantages

  • Maximal working pressure: 46 bar.
  • Compared to an assembly with two separated components (filter drier + receiver)
    – Space gain on the installation
    – Optimisation of assembly time
    – 2 connections to be screwed or brased instead of 4 ; therefore, reducing the risk of leakage
    – One reference to manage instead of two.
  • 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 intake ensures optimal distribution and permanent treatment of the whole refrigerant, inside the filter drier receiver.
  • The copper-plated steel connections facilitate the brazing and allow using brasing alloys with a low silver percentage.
