Mobil SHC Gargoyle 80 POE
Mobil SHC Gargoyle 80 POE is a high-performance refrigeration lubricant specifically developed for compressors operating with carbon dioxide (CO₂ / R-744) refrigerant. It is formulated using advanced polyol ester (POE) technology to deliver outstanding lubricity, wear protection and chemical and thermal stability in high-pressure refrigeration systems. The formulation is designed to maintain effective lubrication even under the demanding operating conditions associated with CO₂ refrigeration technology.
One of the key advantages of Mobil SHC Gargoyle 80 POE is its appropriate miscibility with carbon dioxide refrigerant. The lubricant maintains well-defined viscosity, temperature and pressure relationships, ensuring adequate oil film thickness at high pressures and temperatures. This helps improve shaft sealing, reduce bearing fatigue and support reliable compressor operation.
Mobil SHC Gargoyle 80 POE also provides excellent wear protection and load-carrying capability. The lubricant forms a durable film that helps protect compressor components, contributing to extended equipment life and reduced maintenance requirements. Its naturally high shear-stable viscosity index helps maintain film strength across a wide operating temperature range, supporting consistent lubrication performance.
Another important benefit is its excellent low-temperature fluidity combined with low traction characteristics. These properties help improve evaporator efficiency and may contribute to reduced power consumption. The formulation also helps reduce shaft leakage and maintain stable lubrication performance under severe service conditions commonly associated with CO₂ refrigeration systems.
Mobil SHC Gargoyle 80 POE is recommended for refrigeration systems using carbon dioxide refrigerant, including large industrial reciprocating compressors used in food processing and freezing operations. It is also suitable for cold storage plants, industrial refrigeration systems and marine refrigeration applications requiring reliable CO₂-compatible lubrication.
Physical characteristics include a kinematic viscosity of approximately 78 mm²/s at 40°C and 11.4 mm²/s at 100°C. Mobil SHC Gargoyle 80 POE has a viscosity index of approximately 142, a flash point of approximately 285°C and a pour point of approximately −45°C. The product also provides excellent low-temperature viscosity performance and strong thermal stability, supporting reliable performance in CO₂ refrigeration compressor applications.
