Description
SL-68 synthetic POE oil is developed for HFC-based refrigeration and air-conditioning systems that require a higher viscosity lubricant for larger or high-load compressors.
It delivers exceptional thermal and oxidation stability, helping prevent acid formation and deposit buildup inside the system.
The superior lubricity and miscibility of SL-68 enhance system efficiency and compressor reliability under extreme operating conditions.
⚙️ Key Features & Benefits:
-
✅ Synthetic POE Base Oil: 100% synthetic composition ensures outstanding stability and performance.
-
✅ Excellent HFC Compatibility: Fully compatible with R-134a, R-404A, R-407A/C, R-410A, R-507, and R-32 refrigerants.
-
✅ High Lubrication Strength: ISO 68 grade provides extra protection in heavy-duty and large-capacity compressors.
-
✅ Thermal & Chemical Stability: Minimizes oxidation, sludge formation, and acid generation.
-
✅ Low Moisture Absorption: Maintains purity and prevents hydrolysis even in humid environments.
-
✅ Improved Oil Return: Excellent miscibility ensures efficient oil circulation within the system.
-
✅ Energy-Efficient Operation: Reduces mechanical wear and enhances compressor life.
