Description
🛢️ Bitzer BSE 32 Refrigeration Oil Technical Data
The BSE 32 is a lower viscosity lubricant compared to BSE 55, typically used in smaller compressors or systems operating at lower temperatures.
| Specification | Detail |

| Acid Value | < 0.2\ mg KOH/g |
| Density | Approx. 0.94 to 0.99 (at specific temperature) |
| Application | Refrigeration compressors (reciprocating and screw types) |
| Main Refrigerants | HFC and HFO refrigerants |
| Examples of Compatible Refrigerants | R-134a, R-404A, R-507A, R-407C, R-407A, R-407F, R-513A, R-450A, R-448A, R-449A, R-1234yf (HFOs) |
| Special Use Case | Recommended for HFC/HFO compressors where the condensing temperature (tc)le 55^C (for higher temperatures, the higher viscosity BSE 55 is typically required). |
Compressor Application
BSE 32 is widely used in many Bitzer ECOLINE semi-hermetic reciprocating compressors and various screw compressors that use HFC refrigerants (like R-134a, R-407C, R-404A) and the newer HFO/HFO blends (like R-450A, R-513A, R-448A/R-449A). The lower viscosity is often preferred when the oil needs to travel longer distances or o
