For high-performance compressor lubrication in aging systems, Nu-Calgon 4308-07 Zerol 200TD is the industry standard for alkylbenzene refrigeration oil. This ISO 46 viscosity synthetic lubricant is specifically engineered for systems utilizing CFC and HCFC refrigerants, including R-22, R-502, and high-performance blends like R-401A/B and R-402A/B. As an OEM-approved refrigeration oil, Zerol 200TD is preferred by Copeland for field service due to its specialized additive package, which provides superior extreme pressure (EP) lubricity and controlled foaming during startup. Unlike standard mineral oils, this synthetic alkylbenzene offers enhanced thermal stability and a low floc point, preventing wax precipitation that often leads to expansion valve plugging. Its high solubility ensures efficient oil return in low-temperature evaporators, while its excellent solvency makes it an ideal burnout clean-up oil for emulsifying acid by-products and carbonized deposits. Note that this oil is not for use with HFCs or POE-dependent systems. Key Benefits: Copeland Approved: Strictly formulated to meet the demanding field service requirements of Copeland compressors using HCFC-based blends. Enhanced Thermal Stability: Resists coking and sludge formation under high discharge temperatures and high-pressure conditions. Superior Miscibility: Maintains a homogeneous solution with R-22 refrigerant across wide temperature ranges for reliable oil return to the crankcase. Low Floc Point: Eliminates the risk of waxy deposits at low temperatures, ensuring peak efficiency in commercial refrigeration. Burnout Recovery: High solvency allows for effective emulsification of contaminants, making it the preferred choice for a system flush after a motor failure. Common Questions: Can Zerol 200TD be used in R-410A systems? No, alkylbenzene refrigeration oil is not compatible with HFC refrigerants like R-410A. Those systems require Polyolester (POE) lubricants to ensure proper miscibility and protection. Is this oil compatible with existing mineral oil? Yes, Nu-Calgon Zerol 200TD is compatible with most mineral oils, allowing it to be used for retrofitting or as a heavy-duty replacement for improved performance in systems still running on naphthalenic oils. What does the 'TD' designation indicate? The 'TD' stands for "Tested and Delivered" with a specific additive package for low foaming and extreme pressure protection, distinguishing it from standard Zerol 200 grades. Pick up only.
