Mobil EAL Arctic Series are high-performance, fully synthetic lubricants specifically designed for refrigeration compressors and systems using ozone-friendly synthetic HFC refrigerants, as well as newer HFO refrigerants and HFO/HFC blends with lower Global Warming Potential, including A1 and A2L refrigerants per ASHRAE 34/ISO 817 safety classification. Formulated with proprietary synthesized Polyol Esters (POEs) and a unique additive system, they deliver outstanding lubricity, wear protection, and chemical, thermal and hydrolytic stability, with well-defined viscosity/temperature/pressure relationships and miscibility across a wide range of HFC, HFO and HFO/HFC refrigerants. Mobil EAL Arctic 220 is the ISO VG 220 grade of the series. Its typical kinematic viscosity is 221 mm²/s at 40 °C and 18.1 mm²/s at 100 °C, with a viscosity index of 88, a pour point of -28 °C and a flash point of 285 °C. Like the rest of the series, it is recommended for HVAC, commercial refrigeration (food preservation, transportation) and industrial applications (food processing, freezing), and is used by many major compressor and system builders worldwide. Mobil EAL Arctic oils are hygroscopic and require careful handling to avoid moisture absorption, and must not be used in ammonia (NH3/R-717) systems. Developed in close cooperation with compressor OEMs to meet the stability and compatibility requirements of modern refrigeration applications under the Montreal and Kyoto Protocols and regulations such as the EU F-gas regulation, the series offers very good anti-wear properties for reduced compressor wear, a high viscosity index and wax-free composition for excellent low-temperature fluidity and evaporator efficiency, and a wide viscosity range to match diverse equipment requirements.
