HP SEETUL SE 68 is a superior-quality synthetic ester-based refrigeration compressor oil formulated to deliver exceptional lubrication in compressors operating with HFC refrigerants such as R-134a. This advanced lubricant has been specifically engineered to address the lubrication challenges presented by HFC-based systems, which are non-compatible with traditional mineral oils. Its synthetic ester composition ensures excellent miscibility with these refrigerants, enabling efficient oil circulation, superior heat transfer, and reliable lubrication even under extreme temperature variations. The oil is CFC-free and environmentally responsible, designed to meet the performance requirements of modern refrigeration and air-conditioning systems that comply with global environmental standards. Its exceptional chemical and thermal stability provide consistent performance under both high and low temperature operating conditions, preventing the formation of carbon deposits, sludge, and varnish inside compressors. This stability allows HP SEETUL SE 68 to extend compressor life, reduce maintenance needs, and enhance energy efficiency. HP SEETUL SE 68 offers excellent lubricity and film strength, ensuring smooth and quiet compressor operation while minimizing metal wear and friction between moving components. Its synthetic ester base also provides excellent solubility and refrigerant return properties, which prevent oil trapping and maintain optimal system efficiency. The low pour point of the oil allows it to remain fluid even in extremely low-temperature evaporator conditions, ensuring steady lubrication and reliable startup performance in cold environments. Highly recommended for hermetic and semi-hermetic refrigeration compressors, HP SEETUL SE 68 is particularly suitable for use in air-conditioning systems, chillers, deep freezers, and commercial or industrial refrigeration units using HFC refrigerants like R-134a, R-404A, and R-407C. Its formulation is completely free from chlorine and other ozone-depleting compounds, making it a safe and sustainable choice for modern refrigeration technologies.
