Thus all dirt particles are retained irrespective of flow direction. DMB/DCB filter driers ensure fast and effective adsorption of moisture as well as organic and inorganic acids.

3 Introduction, are for use in liquid lines on heat pumps. 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/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 Biflow 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. DMB filter driers These filters contain a solid core consisting of 00% Å Molecular Sieve. DMB filter driers are especially suitable for heat pumps with HFC refrigerant and polyolester oil with additives. DCB filter driers These filters contain a solid core consisting of Å Molecular Sieve and activated aluminium oxide. DCB filter driers can be used in heat pumps with HCFC refrigerants and mineral oil, and also with HFC refrigerants and polyolester oil. Features Optimum flow characteristics and dirt retention The check valves are not sensitive to dirt and give minimum restriction, irrespective of flow direction Effective dirt removal to 2 μm No dirt released by reversing the flow direction Available with solder (copper) and flare connections Approvals C US UL file no.

Then select the dri er size based on the ad sorp tion and liquid ca pac i ty required. a. Amount of charge: kg R4a at t L = 24 C To dry kg R4a at 24 C from 00 to 60 ppm moisture, a DMB 6 is necessary. b. Cooling capacity: Q e = 2 kw To obtain a mass flow corresponding to 2 kw cooling capacity with a DMB 6 filter drier, a ½ inch connection must be cho sen. Larger connections can be chosen in accordance with the liquid line dimension. c. Result DMB 64 or DMB 6 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.
