Bitzer compressor oil BSE 170

Bitzer BSE 170 is a high-performance Polyol Ester (POE) synthetic lubricant engineered explicitly for the heavy-duty bearings of Bitzer screw compressors. It acts as the vital protective layer that prevents metal-on-metal friction under intense pressure, while seamlessly blending with modern chlorine-free refrigerants to ensure proper oil circulation through the cooling loop.💡 Key TakeawaysThe Oil Type: 100% Synthetic Polyol Ester (POE) with a thick, high-viscosity profile (ISO VG 170).The Match: Purpose-built for Bitzer Screw Compressors (HS, CS, and CSV lines) and heavy-duty multi-compressor industrial racks.Refrigerant Synergy: Fully compatible with HFCs and HFOs like R134a, R404A, R507A, R407C, and R410A.Primary Perks: Delivers exceptional film strength, prevents sludge buildup under extreme heat, and extends compressor lifecycle.Critical Warning: Highly hygroscopic (absorbs moisture from air incredibly fast). Keep containers sealed tight until the exact moment of charging to prevent acid formation.If you are currently servicing a machine, please let me know:The exact model number of your Bitzer compressorThe refrigerant gas currently inside the systemIf you need help finding the right oil capacity (litres) for a full refillI can verify if BSE 170 is the manufacturer-recommended match for your specific unit
