3 MAKING MODERN LIVING POSSIBLE Eliminator Filter driers DCR Excellent moisture and acid adsorption - compact and user friendly Danfoss DCR Eliminator filter driers with replaceable solid cores are a compact and user friendly solution. As well as being able to meet even the most demanding requirements (e.g. high working pressure levels when operating with R410A and CO 2 ) the wide product range gives you the possibility to perfectly match the filter drier to the plant. The drier shell can be supplied to fit one to four cores. The solid cores are supplied in three distinct options. The DCR can be supplied with pure copper or steel connections for soldering or welding in various sizes. DCR is available in both standard and high pressure versions. REFRIGERATION & AIR CONDITIONING DIVISION

4 DCR: compact design for easy installation and service DCR filter driers protect refrigeration and air conditioning systems from moisture, acids and solid particles. They utilise (a) replaceable solid core(s) and are suitable for liquid and suction line installation in both single and multi-compressor configurations. The solid core assures a high drying capacity and avoids acid formation in the system. Features Corrosion-resistant powder-paint finish including zinc-phosphate pre-treatment Core holder for fixing the core in position. The welding version allows soldering into copper tubes with Silver-flo 55 and Easy-flow flux. Connections for solder (copper/steel) or welding (steel). Standard or high pressure top cover. Standard program for working pressures below 35 bar. High pressure versions available for applications up to 46 bar. Filter to catch possible loose particles. Helium leak tested housings for 1-4 cores. Three different core types available. Strainer is an option. Top cover with or without external access port. Applications Advantages Facts Commercial plants with fluorinated refrigerants or CO 2. Industrial plants with fluorinated refrigerants or CO 2. Highly efficient dirt retaining capabilities on both the suction and the liquid line. Can be used in all environments, including marine applications. The new core holder requires minimum free space to remove the core for replacement. One of the 8 holes for fixing the screws in the cover has a split screw hole to keep the cover in place (very easy to place the cover back in position and fix the screws). Can be installed in any position DM core for liquid line application (100% molecular sieve for HFC). Provides high moisture adsorption at low and high condensing temperatures. Effective protection against impurities DC core for liquid line application (80% molecular sieve and 20% activated alumina for CFC and HCFC). Effectively adsorbs moisture and acid in the system DA core for suction line after a compressor burn-out (30% molecular sieve and 70% activated alumina for CFC/HCFC/HFC) F strainer for suction line.
