In recent decades, the refrigeration compressor industry has gone through a major transformation due to the environmental impact of refrigerant gases. CFCs (Chlorofluorocarbons) and HCFCs (Hydrochlorofluorocarbons) have been widely used for years due to their excellent thermodynamic properties. However, these refrigerants cause environmental impact and have been slowly replaced by HFC refrigerant gases. Suniso has developed solutions over the years that can meet all issues regarding refrigeration compressors.
The adoption of more sustainable solutions
With the introduction of the Montreal Protocol, a process of phased replacement of CFCs and HCFCs was initiated. In their place, HFCs (Hydrofluorocarbons), chlorine-free refrigerants that are less harmful to the environment, were developed. HFCs offer a good compromise between performance and eco-friendliness.
The need for advanced lubricants: solutions from Suniso
This evolution has made it essential to use lubricating oils compatible with refrigeration compressors, capable of ensuring high performance, efficiency and component protection. Suniso with its products provides a solution to the problems and continuous innovation in the refrigeration industry. Suniso GS and Suniso SL lubricating oils offer effective lubrication solutions for both traditional CFC and HCFC refrigerants and modern refrigerants such as HFCs.
Suniso GS: a reliable solution for CFC and HCFC refrigerants
Suniso GS lubricants are the ideal choice for compressors that use conventional refrigerants such as CFCs and HCFCs. Due to their formulation based on high-quality mineral oils, they offer a number of advantages:
- Wide temperature range: Suniso GS lubricating oils provide excellent performance at low temperatures without wax buildup.
- Chemical and thermal stability: these lubricants reduce the risk of reactions with coolant and metal system components, prolonging machine life.
- Versatility: Suniso GS lubricants are also compatible with natural refrigerants such as ammonia and isobutane.
Suniso SL: the modern answer for HFC refrigerants
For systems using new generation refrigerants such as HFCs, Suniso SL lubricants, based on synthetic polyester(POE), are the ideal choice. Their main features include:
- Optimal miscibility-Suniso SL lubricating oils facilitate oil return to the compressor, improving system efficiency and preventing oil buildup.
- Component protection: these products maintain stable viscosity even in the presence of dissolved coolant, reducing mechanical wear.
- Superior thermal stability: Suniso SL lubricants are ideal for a wide range of applications, from low-temperature refrigeration systems to high-temperature heat pumps.
With their compatibility with modern refrigerants, Suniso SL supports companies in achieving sustainability goals without compromising performance.
Innovation and reliability for refrigeration
The evolution of refrigerants requires advanced and specialized lubrication solutions. With Suniso GS and Suniso SL, it is possible to effectively meet the needs of systems using both traditional and next-generation refrigerants. These products represent the result of decades of innovation, ensuring efficiency, protection and long-term reliability.
