SL68 Oil

 Introduction
Rubo Al Hail International Enterprise L.L.C., Muscat, Oman supplies the SL68 Oil—a premium synthetic lubricant tailored for medium‑duty HVAC and refrigeration compressors operating with HFC refrigerants. As a well‑established AC spare parts supplier in Muscat, we know that selecting the correct oil grade—especially in Oman’s high‑ambient environments—is a key factor in maintaining system performance, reliability and longevity.

For systems such as light commercial chillers, medium‑capacity rooftop units or multi‑split air‑conditioning installations, the SL68 Oil offers the right balance of viscosity, film strength and thermal/chemical resilience to stand up to continuous duty.

What It Does in HVAC Systems
SL68 Oil functions as the lubricant within the compressor of an HVAC or refrigeration system. It ensures that bearings, pistons, scrolls or screws operate with minimal friction, helps maintain internal sealing, supports heat transfer and returns with the refrigerant to the unit’s sump. In systems utilising HFC refrigerants such as R134a, R404A or R407C, a synthetic lubricant with ISO VG 68 ensures robust film strength—particularly in systems subject to high load, multiple starts, frequent cycling or extended run hours—common in commercial buildings across Muscat and Oman.

Using the correct oil ensures improved compressor protection, reduced wear, lower energy consumption and extended service life. In Oman’s environment, where ambient heat and humidity create additional stress, investing in the right lubricant can reduce unplanned maintenance and increase uptime.

Detailed Specifications & Technical Insights
For the SL68 Oil we supply:

• Viscosity Grade: ISO VG 68, providing a thicker film than low‑viscosity oils—ideal for compressors handling moderate to high loads. 
• Base Type: Synthetic (POE or similar) to ensure miscibility and performance with HFC refrigerants. 
• Thermal Stability: Designed for high ambient temperature operation, resisting breakdown and deposit formation even under heavy duty. 
• Moisture Resistance: Controlled moisture content to preserve insulation integrity and avoid corrosion, particularly important in humid conditions. 
• Wide Compatibility: Suitable for use in screw, scroll, reciprocating and semi‑hermetic compressors rated for commercial HVAC systems. 

Selecting SL68 Oil for the right application ensures the compressor operates within its intended lubricant specification, reducing risk of overheating, oil foaming or premature failure.
