Overview
Valeo® has announced an update to the lubrication specification used across its TM series compressor range.
To support the increasing adoption of modern refrigerants, Valeo® is transitioning from ZXL100PG oil to VC100YF oil as the new production standard for TM compressors.
This change is designed to simplify servicing, improve compatibility, and ensure compressors remain suitable for both current and future refrigeration systems.
Affected Compressor Models
The lubrication update applies to the following Valeo® TM compressors:
-
TM08
-
TM13
-
TM15
-
TM16
-
TM21
The estimated implementation date for compressors supplied with the new oil specification is July 2026.
Dual Refrigerant Compatibility
The new VC100YF lubricant has been developed to support operation with both of the following refrigerants:
-
R134a
-
R1234yf
This allows a single compressor specification to be used across different systems and reduces the risk of incorrect oil selection during installation or servicing.
Benefits of VC100YF Oil
The introduction of VC100YF oil provides several advantages.
Universal compressor application
VC100YF oil allows Valeo® TM compressors to operate with both R134a and R1234yf refrigerants.
Simplified maintenance
Using a single oil type across multiple compressor models reduces the risk of incorrect oil usage during servicing.
Future-ready design
The new oil specification ensures compressors remain compatible with evolving environmental standards and refrigerant technologies.
Oil Technical Characteristics
The new VC100YF lubricant provides similar viscosity performance to the previous ZXL100PG oil while enabling compatibility with both refrigerant types.
| Characteristic | VC100YF | ZXL100PG |
|---|---|---|
| Target refrigerant | R134a / R1234yf | R134a |
| Viscosity grade @100°C | VG9 | VG10 |
| Viscosity @100°C | 9.6 mm²/s | 10.4 mm²/s |
| Viscosity index | 216 | 215 |
| Density @15°C | 0.9886 g/cm³ | 1.006 g/cm³ |
| Flash point | 182°C | 215°C |
| Pour point | -50°C | -50°C |
These properties ensure reliable compressor lubrication across a wide range of operating conditions.
Validation Testing
Valeo® conducted multiple validation tests to confirm the performance and reliability of the new oil specification.
Testing included:
-
Thermal stability testing
-
Sealed tube and FALEX wear testing
-
O-ring compatibility testing
-
Performance testing
-
High speed interruption testing (7000rpm ON/OFF)
-
Gas shortage testing
-
Oil migration testing
-
Liquid compression testing
-
Electric erosion testing
All tests confirmed acceptable performance with the VC100YF lubricant.
