Description
🛠️ Key Technical Data for Bitzer BSE 170
| Property | Value | Notes |
| Oil Type | Polyolester (POE) Synthetic Oil | Designed for excellent compatibility with HFC refrigerants. |
| Viscosity Grade | ISO VG 170 (typically) | Indicates the oil’s thickness or flow characteristics at a specific temperature. |
| Flash Point | approx 265^C (Open Cup) | The lowest temperature at which the liquid gives off enough vapor to form an ignitable mixture near the surface. |
| Relative Density | approx 0.95 (Water = 1) | The ratio of the oil’s density to the density of water at a given temperature. |
| Packaging Sizes | Varies (e.g., 1L, 5L, 10L) | Common commercial and industrial container sizes. |
| Refrigerant Compatibility | HFCs (e.g., R134a, R404A, R407C, R410A) | The POE base fluid provides the necessary miscibility for oil return in the system. |
| Primary Use | Refrigeration and Air-Conditioning Compressors | Specifically for Bitzer screw and reciprocating compressors. |
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.
