Filter drier, shell Types DCR and DCRE

Danfoss ELIMINATOR® lter drier with replaceable solid core. Designed for applications requiring high moisture capacity and acid adsorption capacity.

Danfoss ELIMINATOR® lter 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 oers exibility with respect to dierent applications.

Available with copper connections. DCRE programme oers to be used with ammable 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

nish

• 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

• Eective 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 eective dirt removal and low pressure drop. The robust solid cores withstand pressure surge and vibration.

Figure 2: DCRE

Inner taper of core should always face towards lter 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.

Applications

Danfoss ELIMINATOR® lter driers with replaceable solid core, type DCR / DCRE, protect refrigeration, freezing and air-conditioning systems from moisture, acids, and solid particles.

With these contaminants eliminated, systems are safer from harmful chemical reactions and from abrasive impurities.
