I am in search of information regarding the best lubricants to use for a temperature range spanning from -40 to 150 degrees. This pertains to a horizontal plate and chain conveying system located in a product freezing box (known as the Glacier-600). In the absence of any manufacturer recommendations, I am questioning the suitability of the currently used grease (SFL-1) and chain oil (Food grade chain oil). Concerns arise about the ability of the grease to remain in place during cleaning, as 90% of failures have been attributed to the chain damaging the sprocket teeth in this system, which consists of 25 sprockets. Is it possible that the current grease is causing excessive friction at low temperatures, thereby placing additional strain on the chain and sprocket system? Is there a risk of the current grease melting away during cleaning? What would be the most suitable chain lubricant to use in this scenario?
Your issue involving a mix of hot and cold temperatures piqued my interest. I suggest sharing it within the Lubrication technology community, as there are numerous specialists in the field who may be able to provide insight. While we have experience with oxygen pumps in cryogenic environments, we have not encountered hot conditions. Could you please specify if the temperature is in degrees Celsius or Fahrenheit? Thank you.
Are you looking for a high-quality product for your chain application? Consider exploring Mobil Gargoyle SHC 226, an ISO 68 refrigeration compressor oil with a pour point of -45 degrees and a VI of 145. This product is H1 food grade certified, making it safe for use in food processing applications. Our experience with the ISO 220 version as a food grade gearbox oil has been exceptional, boasting longevity and durability even in extreme conditions. Whether used as a chain lube or in outdoor settings with temperatures as low as -30 degrees, Mobil Gargoyle SHC 226 delivers reliable performance. Additionally, stay tuned for Mobil's upcoming synthetic food grade grease set to launch by the end of the year. Wishing you success in finding the perfect solution for your needs!
Hello Bunny Man, I see that you are currently using FMC FrigoScandia Spiral Freezer equipment, which functions with low temperatures. The lubricant provided by FMC, stocked in your facility, will be suitable for your Glacier-600 system. I recommend checking the MSDS to confirm compatibility.
Assessing your current scenario and temperature range, it seems like you might need a lubricant with both low-temperature fluidity and high-temperature stability. In this context, synthetic lubricants could be a suitable option since they generally exhibit good thermal stability and can maintain their viscosities across a wide temperature range. It might be worth reviewing any potential chemical or compatibility issues with the machinery or cleaning procedures. As for your question on whether the current grease is causing excessive friction at low temperatures, it might be the case if the grease is not designed for such low temperatures which can result in thickening, reduced flow, and less effective lubrication. Manufacturer-specific lubricant suggestions, if available, would also be a great guiding line. It's essential to ensure proper lubrication in order to avoid such failures and hence, a detailed assessment of the operating conditions, machinery, and cleaning procedures should be considered. Always remember, a good lubricant not only reduces friction but also protects surfaces.
Understanding your concern regarding the grease's behavior in the extreme temperature range, it's pivotal to ensure the lubricant's properties align with the system's requirements. If you suspect the current grease (SFL-1) is not performing effectively at low temperatures, a high performance, synthetic grease might be a good alternative. They often maintain their performance over a wide temperature range, reducing friction even in extreme cold. As for the cleaning process, you might consider a lubricant with a high dropping point to prevent it from melting away. But remember, the choice also heavily depends on the compatibility with materials in your system. The food-grade chain oil should most likely be sufficient for use in the chain and sprocket system, unless signs of degradation or inadequate lubrication persist. Consulting with a lubrication specialist may provide more personalised advice for your system.
It sounds like you're dealing with quite a challenging situation. Generally, standard greases might struggle at extremely low temperatures, potentially leading to increased friction and wear, which can definitely contribute to damage in your system. SFL-1 may not be the best choice in such a wide temperature range, especially if it's not specifically designed for low-temperature performance. You might want to look into synthetic lubricants or greases that are formulated for extreme temperature ranges, as they tend to maintain their consistency better during cleaning and provide superior protection against wear. Consider options like high-performance food-grade lithium grease or even specialty chain oils designed for cold environments, as they can offer better adherence and reduce the chance of washing away during maintenance. Additionally, always check compatibility with your materials to ensure optimal performance!
