1. Wide Refrigerant Compatibility (Versatility)
-
One-Oil Solution: It is marketed as a single lubricant that can be used across a broad range of refrigerant types, simplifying inventory and service procedures.
-
HFCs: Excellent performance with standard Hydrofluorocarbons like R-134a, R-404A, R-407C, R-410A, and R-507A.
-
HFOs: Compatible with new Hydrofluoroolefin refrigerants such as R-1234yf (common in car A/C) and various HFO blends.
-
A2L Refrigerants: Works well with mildy flammable refrigerants like R-32 and R-454B.
-
Natural Refrigerants: Applicable for systems using CO2 (R-744).
-
Note: It is generally Not Recommended for Ammonia (R-717) systems.
2. Enhanced Oil Return and Miscibility
-
Patented Technology: The blend of mineral oil and POE is engineered to leverage the strengths of both.9 The technology ensures effective oil return to the compressor, which is a critical function, especially in systems using HFC/HFO refrigerants where pure mineral oil would not be miscible enough.
3. Performance and Stability
-
Outstanding Lubricity: Provides excellent lubricity and wear protection to the compressor components (bearings, pistons, scrolls).
-
Chemical Stability: Exhibits superior chemical stability to resist breakdown and reaction with the refrigerant or materials within the system, ensuring a long service life.
4. Cost and Logistics Advantages
-
-
Cost-Effectiveness: Provides a cost advantage compared to using traditional, full-synthetic lubricants (like 100% POE, PAG, or PVE) while offering similar or broader compatibility.
-
Inventory Consolidation: Simplifies logistics and prevents misapplication by allowing technicians to use one oil for multiple refrigerant types.
Thermal Stability: Offers high thermal stability, minimizing carbon deposits or sludge formation at high-temperature discharge points.
5. Applications
-
Suitable for a wide variety of compressor types and systems, including:
-
Air Conditioners (Room and Commercial)
-
Refrigerators and Freezers
-
Showcases
-
Refrigerated Vehicles
-
Various compressor designs (Scroll, Reciprocating, Vane, Swash Plate)
-
The Suniso Hybrid VG 46 is positioned as a reliable, high-performance maintenance oil for servicing modern systems, particularly where the original lubricant type might be unknown or where a single product is preferred for general HFC/HFO maintenance.
