Description
🎯 Key Application and Features
The exceptionally high viscosity of BSE 170 dictates its specialized application.
Primary Application
The BSE 170 is the standard oil fill for most of Bitzer’s compact screw compressors (CSH, CSVH series) and is essential for the reliable lubrication and sealing of the large rotor clearances in these units.
Features
- Screw Compressor Optimization: The high viscosity is necessary to create the required thick oil film for sealing and lubricating the rotors and bearings in screw compressors, especially at high operating temperatures and pressures.
- Refrigerant Compatibility: Like the other BSE oils, it is fully compatible with HFC refrigerants (e.g., R134a, R404A, R407C, R507A, R410A) and low-GWP HFO refrigerants.
- Thermal Stability: It offers high chemical and thermal stability, which is crucial given the high discharge temperatures often found in screw compressor operation.
- Hydroscopic Nature: As a POE oil, it is hygroscopic (absorbs moisture), requiring careful handling to minimize contact with ambient air during system charging.
