Filter drier, shell
Types DCR and DCRE
Danfoss ELIMINATOR® filter drier with replaceable solid core.
Designed for applications requiring high moisture capacity and acid adsorption capacity.
Danfoss ELIMINATOR® filter driers with replaceable solid core, type DCR, are for use in liquid and / or suction lines in refrigeration, freezing and air-conditioning systems.
Besides being able to meet the demanding requirements of high working pressure levels when operating with R410A thanks to replaceable solid cores the DCR programme offers flexibility with respect to different applications.
Available with copper connections. DCRE programme offers to be used with flammable refrigerants A2L, Group .

Filter drier, shell, types DCR and DCRE
Features
DCR / DCRE housing:
•PED approved for PS up to 46 bar for the DCR and up to 50 bar for DCRE
•DCR / DCRE housing (including core holder) are made entirely of steel and are thus compatible with all refrigerants
•DCR / DCRE housings have undergone phosphate pre-treatment and have a corrosion-resistant powder-paint finish
•DCR / DCRE housings are helium leak tested
Top covers for DCR / DCRE housings:
• Zinc-chromated steel top covers with or without external access connection
Inserts for DCR housings - strainer 48 - F strainer - compatible with all refrigerants:
•Retains dirt particles larger than 15 μm
•For use direct in DCR housings
•Utilised in the suction or liquid line
Inserts for DCR housings - solid cores
48 - DM - 100% molecular sieve solid core suitable for HFC refrigerants:
•Provides high moisture adsorption at low and high condensing temperatures
•Effective protection against impurities
48 - DC - 80% molecular sieve and 20% activated alumina solid core suitable for HCFC refrigerants and compatible with HFC refrigerants:
• Adsorbs moisture and acid in the system throughout the entire temperature range
48 - DA - 30% molecular sieve and 70% activated alumina solid core suitable after compressor burnout and compatible with HCFC / HFC refrigerants:
Inserts for DCRE housings - solid cores:
•48 - DM
•48 - DC
All solid cores have an optimised uniform grain size ensuring effective dirt removal and low pressure drop. The robust solid cores withstand pressure surge and vibration.

Inner taper of core should always face towards filter outlet. This apply for DCR and DCRE components.
NOTE:
The DCRE can only be use for A2L when the solid core is placed. DCRE is not allowed to be used as receiver.
