Product Description

Mobil EAL Arctic Series are high performance  fully synthetic lubricants specifically designed for the lubrication of refrigeration compressors and systems using ozone-friendly synthetic HFC refrigerants as well as recently developed HFO refrigerants and HFO/HFC blends with lower Global Warming Potential than HFC’s, including A1 and A2L refrigerants as per ASHRAE 34/ISO 817 safety classification.

Mobil EAL Arctic Series oils are formulated with proprietary synthesized Polyol Esters (POEs) and a unique additive system to provide outstanding lubricity, wear protection, chemical and thermal stability, and hydrolytic stability.

They are miscible with HFC, HFO and HFO/HFC refrigerants and have well-defined viscosity / temperature / pressure relationships with a wide range of those refrigerants. Performance of the Mobil EAL Arctic Series has been well documented with HFC, HFO and HFO/HFC blends in a broad range of refrigeration and air conditioning systems and are used by many major compressor and system builders around the world.

Mobil EAL Artic Series are recommended for use in HVAC (Heating, Ventilation, Air Conditioning), Commercial and Industrial Refrigeration.

Features and Benefits

Mobil EAL Arctic Series Lubricants are recognised and appreciated around the world for their excellent performance with a wide range of refrigerants and operating conditions. Mobil EAL Arctic Series was designed to complement the new generation of ozone-friendly and lower Global Warming refrigerants mandated by the Montreal and Kyoto Protocols followed by even more stringent regional agreements such European F-gas regulation. A key factor in the development of Mobil EAL Arctic Series of lubricants was our close contacts with key compressor OEMs and system designers to ensure that our product offerings will provide exceptional performance in a wide range of applications.

This work in combination with our lab testing has helped confirm the exceptional performance of the Mobil EAL Arctic Series. This cooperative work allowed an optimum design of synthetic POE molecules for each viscosity grade in the series and the development of an additive package to meet the stability and compatibility requirements for refrigeration applications.

Features Advantages and Potential Benefits
Excellent high temperature stability Improved evaporator cleanliness, less unscheduled downtime and reduced maintenance costs
Well defined miscibility and P-V-T relationships with HFC refrigerants Assures high system efficiency and proper oil return in refrigeration system designs
Very good anti-wear properties Reduced compressor wear resulting in lower maintenance costs
High Viscosity Index and wax-free Excellent low temperature fluidity, no waxy deposits and improved evaporator efficiency
Wide viscosity range Can meet specific viscosity requirements of a wide range of equipment and applications


Application considerations: Mobil EAL Arctic Series oils are hygroscopic and care must be taken to avoid moisture absorption during handling. Packages should be tightly closed when not in use, and small packaging preferred. Product should not be transferred to plastic containers that may allow moisture ingress.

Mobil EAL Arctic Series are recommended for refrigeration systems where HFC, HFO and HFO/FHC blends refrigerants are used. The application range is wide from Domestic/Tertiary applications (Heating, Ventilation, Air Conditioning HVAC) to commercial applications (food conservation, transportation) and industrial applications (food processing, freezing).

Mobil EAL Arctic Series must not be used in ammonia systems (NH3 / R-717).
