ELIMINATOR Hermetic bi-flow filter drier Types DMB and DCB

Transcription

1 Data sheet ELIMINATOR Hermetic bi-flow filter drier s DMB and DCB Hermetic bi-flow filter driers, types DMB and DCB are for use in liquid lines on heat pumps. Hermetic bi-flow filter driers have built-in check valves which ensure that refrigerant liquid always flows through the filter driers from the outer side of the filter core towards the center. Thus all dirt particles are retained irrespective of flow direction. DMB and DCB filter driers ensure fast and effective adsorption of moisture as well as organic and inorganic acids. When building heat pump systems, the use of bi-flow filters can, depending on the type of system, save up to ten solder connections. This reduces production costs and the number of potential leakage points. Available with flare and solder (cu-plated steel) connections. For other connections please contact your Danfoss Sales Representative. Features The Core type DMB 00% 3Å Molecular Sieve core High drying capacity minimizing the risk of acid formation (hydrolysis) Recommended for use with HFO, HC, HFC and HCFC refrigerants Will not deplete oil additives The Core type DCB 80% 3Å Molecular Sieve with 20% activated alumina Perfect core blend for systems that operate at high condensing temperatures and require high drying capacity Recommended for use with HFO, HC, HFC and HCFC refrigerants The Shell PED approved for PS 46 bar Available with flare and solder (cu-plated steel) connections Optimum flow characteristics and dirt retention The check valves are not sensitive to dirt and give minimum restriction, irrespective of flow direction The Filter Effective dirt removal to 25 μm No dirt released by reversing the flow direction Available in sizes 8 30 cubic inches Danfoss DCS (za) DKRCC.PD.ED0.D H098

Many oil additives are also polar substances and can be adsorbed by the activated alumina, rendering them useless, and reducing the drier s acid capacity, though this is not harmful to the system Selection example Select the appropriate type (DMB or DCB) based on refrigerant and oil type. Then select the drier size based on the adsorption and liquid capacity required. a. Amount of charge: 5 kg R34a at tl = 24 C To dry 5 kg R34a at 24 C from 050 to 60 ppm moisture, a DMB 6 is necessary b. Cooling capacity: Qe = 25 kw To obtain a mass flow corresponding to 25 kw cooling capacity with a DMB 6 filter drier, a 2 inch connection must be chosen. Larger connections can be chosen in accordance with the liquid line dimension c. Result DMB 64 or DMB 65 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.
