DDNCY

Cleaning and decontamination of refrigerant circuits in refrigerating and air conditioning installations with change over in flow direction, including heat pumps.

Temporary uses:

new installations during start-up period for a very efficient protection of compressors against all types of dirts.
existing installations for an efficient cleaning of the refrigerant after compressor burnout.

Technical documentation

Maximal working pressure: 46 bar.
Bi-flow filter drier with very low pressure loss thanks to a CARLY patented internal check valve system ensuring an optimum circuiting of the flows.
High effectiveness in the neutralisation of acids and fixing of waxes and sludge at all temperatures thanks to a rigorous selection and a wise mixture of chemical agents present in the cleaning filter driers : molecular sieves, activated alumina, activated carbon.
Drying and depollution of the coolant fluid ensured for the subcritical CO2 applications at low temperatures.

Chemical agents in the form of free grain, for increased performance and elimination of the risk of polluting the circuit with solid particles, consecutive to drying core break-up.
No risk of discharge of the pollutants trapped inside the filter driers, during change over in flow directions.
Very economical cleaning process with no loss of time, because the installation is still running during the operation.
Environmental protection and savings of refrigerant, because using these cleaning filters allows re-use of the refrigerant after pollution control.
