Danfoss Filter driers 数据表 8 Pages
Danfoss Filter driers, with their solid core technology, excel in removing moisture and acid from liquid lines in refrigeration, A/C systems, and refrigerated containers. Choose the DN filter for systems using HCFC refrigerants or the DU filter for HFC refrigerants. Both models offer effective filtering down to 20 µm and can be installed in any position with the arrow indicating flow direction. Their robust solid core withstands pressure surges and vibrations without releasing dust into the system, ensuring reliable performance.

Filter driers with solid core, type DN and DU
DN and DU filter driers with solid core are for use in liquid lines in refrigeration and freezing systems, A/C systems and refrigerated containers.
DN filters have a solid core composed of
Molecular Sieves and activated aluminium oxide.
This makes the DN filter suitable in applications where moisture and acid must be absorbed. DN is the correct choice for systems using HCFC refrigerants, but can also be used for HFC refrigerants.
DU filters have a solid insert with 100%
Molecular Sieves, which are recommended for refrigerating systems using HFC refrigerants, R
134a, R 404a, etc.
DU filters have been specially designed for refrigerating and A/C systems where high water adsorption is required. DU filters do not contain aluminium oxide and can therefore be used with all types of compressors. They are therefore particularly suitable for systems using polyolester with additives.

Selection
Example
Type designation
Filter driers with solid core, type DN and DU
DN and DU are selected on the basis of:
1. Refrigerant and oil (see table).
2. The quantity of refrigerant in the system.
3. The refrigerant capacity of the system.
The refrigerant quantity is used to determine the amount of desiccant necessary to dry the refrigerant and oil.
The refrigerant capacity is used to determine the necessary pressure connection size.
Type selection is made considering the application

1 ) For CFC systems, DN filter driers are recommended. In these systems, circumstances may require the use of a filter drier with acid adsorbing properties.
2 ) Use of filter driers containing activated alumina are not recommended in systems with oils containing additives.
)
1. Amount of charge:
7 kg R 22 at t l
= 24°C
To dry 7 kg R 22 from 1050 to 60 ppm moisture, a DN 08 is necessary.
2. Cooling capacity:
Q e
= 27 kW
To obtain a mass flow corresponding to 27 kW cooling effect with a DN 08 filter drier, a 12 mm connection must be chosen.
Larger connections can be chosen in accordance with the liquid line dimension.
3. Result
A DN 084 or DN 084s can be used.
If the initial moisture content is very small or a planned change of the filter drier is considered, a smaller filter drier size can be chosen.

Dimensions and weights
Filter driers with solid core, type DN and DU
The relatively large diameter of the filter drier means that through-flow liquid velocity is suitably low and pressure drop slight.
Powder formation is eliminated since the solid core grains cannot move against each other.
