Abstract (en)
[origin: EP1048909A2] A refrigerant dehydration filter has an external tube (11,12) sealed at one end to define a return cavity. An internal tube (20) is provided coaxially with the external tube (11,12) and a first external connection (30) is made to the external tube (11,12) with a second external connection (31) being made to the internal tube (20) to facilitate the transfer of refrigerant between the tubes. At least one of the tubes includes desiccating material (21). Preferably, the desiccating material (21) is contained within the external tube (11,12) and the external tube (11,12) provides a substantially larger cross-sectional area compared to the internal tube (20). <IMAGE>
