Oil Separator With Capillary Throttle — Special Design for Small Hermetic Compressor Freezers to Oil Successfully (BOS4808) Overview The BOS4808 oil separator with integrated capillary throttle is engineered specifically for small hermetic compressor freezers. Its purposebuilt design improves oil to the compressor, helping maintain lubrication, reduce wear, and stabilize refrigeration performance in compact systems. Key benefits Restores and maintains oil circulation: The capillary throttle controls refrigerant and oil flow so oil is returned efficiently to the compressor crankcase. Reduces compressor wear and downtime: Proper oil protects bearings and moving parts, extending compressor life and lowering service frequency. Designed for small hermetic compressors: Optimized geometry and flow characteristics make it suitable for compact freezer systems where conventional separators may underperform. Simple replacement or upgrade: Designed for direct use in refrigeration service and maintenance without complex system changes. Main features and attributes Functionality: Separates oil from refrigerant vapor and meters oil through an integrated capillary throttle to ensure steady, controlled oil flow back to the compressor. Compatibility: Intended for small hermetic compressor freezers and refrigeration systems that require improved oil management. Model: BOS4808. Design: Specially shaped internals and capillary throttling element sized for smallcapacity hermetic compressors to optimize oil recovery without compromising refrigeration flow. Construction: Built for refrigeration use with materials and sealing methods appropriate to system pressures and refrigerants (designed as an OEM/service part for compressorfreezer applications). Performance: Promotes reliable oil under typical operating conditions for small freezers, reducing oil logging in evaporator coils and improving system stability. Use cases / applications Freezer compressor maintenance and : a worn or ineffective separator with BOS4808 to restore proper oil after compressor servicing. OEM or retrofit in compact refrigeration units: Integrate BOS4808 into small hermetic freezer designs or retrofit older units that show oil carryover or poor oil circulation. Commercial and household small freezers: Improve longterm reliability in medical, laboratory, or consumerfreezer equipment that uses small hermetic compressors. Installation and service notes Intended as a component replacement; follow compressor and system manufacturer instructions for mounting orientation, brazing/welding, and leak testing. Match system refrigerant and service practices; verify compatibility with the compressor model and line sizes before installation. Routine monitoring of oil level and compressor performance after installation is recommended to confirm proper operation. Model identification Model: BOS4808 — oil separator with capillary throttle, specially designed for small hermetic compressor freezers to oil successfully. This product is focused on improving oil management in small hermetic compressor freezer systems by combining oil separation and capillary throttling in a compact, applicationspecific design.
