Emkarate RL68H Compressor Oil for HFC Refrigeration Systems
A compressor is the heart of every cooling system, and the right oil keeps it beating. Use the wrong lubricant with modern HFC gases, and you risk poor oil return, worn bearings and early compressor failure. At Wisdo Merchants, we supply genuine Emkarate RL68H compressor oil to refrigeration technicians, HVAC contractors and maintenance teams across Nairobi and Kenya.
Emkarate RL68H is a fully formulated synthetic polyol ester (POE) lubricant made by Lubrizol. It belongs to the ISO VG 68 viscosity grade and is designed specifically for HFC refrigerants. As a result, it mixes properly with the gas and returns to the compressor reliably, even at low evaporating temperatures.
Features and Benefits of Emkarate RL68H Compressor Oil
- Made for HFC refrigerants. It is fully miscible with gases such as R134a, R404A, R407C, R410A and R507, so oil circulates and returns properly.
- Stable viscosity across temperatures. With a high viscosity index of about 120, it keeps protecting the compressor through hot and cold operating swings.
- Excellent wear protection. It forms a strong lubricating film that protects bearings, pistons and screw rotors.
- High thermal stability. A flash point of about 270 °C means it resists breakdown at high discharge temperatures.
- Trusted by manufacturers. Emkarate RL oils carry approvals from leading compressor makers, including Carlyle.
For you, this means longer compressor life and fewer costly breakdowns. Meanwhile, your clients benefit from efficient, reliable cooling.

Applications of Emkarate RL68H Compressor Oil and How to Use It
- Reciprocating and semi-hermetic compressors in commercial refrigeration
- Screw compressors in chillers and industrial cooling
- Cold rooms and low-temperature systems running our freezer-grade HFC-404A or R507
- Air conditioning and chiller retrofits from R22 to our R22-replacement HFC-407C
- Topping up and recharging HFC systems after repairs
Converting an R22 System to HFC Gas
Picture a supermarket cold room switching from R22 to an HFC gas. First, the technician recovers the old refrigerant and drains the mineral oil. Next, they fill the compressor with Emkarate RL68H and run the system briefly. After that, they drain and refill the oil, often repeating the flush until little mineral oil remains. Finally, they replace the filter drier, pull a deep vacuum and charge the new gas.
Always check that the compressor manufacturer specifies an ISO VG 68 POE oil before use. Some smaller compressors need a lighter grade.
Keep It Dry
POE oils are strongly hygroscopic, meaning they absorb moisture from the air quickly. Moisture inside the system can form acids and damage the compressor. Therefore, keep containers tightly sealed, open them only when needed and use the oil promptly.
Safety and Handling
- Avoid skin and eye contact. Wear gloves and safety glasses when handling oil.
- Keep containers sealed. This prevents moisture absorption and contamination.
- Store properly. Keep containers in a cool, dry place away from direct sunlight and heat.
- Never mix oil types carelessly. Follow the compressor maker’s guidance before mixing POE with other lubricants.
- Dispose of used oil responsibly. Hand used oil to an approved waste collector rather than pouring it away.
Frequently Asked Questions
What is Emkarate RL68H used for?
It lubricates refrigeration and air conditioning compressors running on HFC refrigerants. It is especially common in commercial refrigeration, chillers and screw compressors.
Can I use RL68H with R22?
Yes, POE oil is compatible with R22. However, its main purpose is HFC systems and R22-to-HFC retrofits. Mineral oil remains standard for systems staying on R22.
Can I mix RL68H with mineral oil?
Small amounts of residual mineral oil are acceptable during a retrofit. Even so, aim to remove as much mineral oil as possible for best oil return with HFC gases.
What does “68” mean in RL68H?
It refers to the ISO viscosity grade. An ISO VG 68 oil has a viscosity of around 68 cSt at 40 °C.
