?? Advancing Refrigeration Performance: A Case Study: Zerol ? Alkylbenzene Lubricants with Ammonia ??

Shrieve worked with The Alhambra Brewing Facility in Granada, Spain as the company embarked on a journey to enhance their refrigeration system.?

Shrieve’s Zerol? 350 alkylbenzene lubricant demonstrated exceptional capabilities, ensuring the refrigeration system's optimal performance for an intensive three-and-a-half year monitoring period of approximately 14,500 hours. The oil retained its original properties, without degradation; and there was no evidence of change in viscosity, total acid number, or products of oxidation.

A machine that previously required annual oil drains to maintain the lubricant properties was shown to be in exceptional condition after three years using the alkylbenzene lubricant.

Here are the key takeaways from the three-year case study:

??Clean and Protected: The refrigeration system experienced no residues from wear, no debris, and no decomposition materials. The alkylbenzene lubricant effectively safeguarded the compressor's moving components, ensuring longevity.

??Unchanged Performance: The new compressor, with the alkylbenzene lubricant, seamlessly integrated into the existing system. The unit's performance remained normal, with no mechanical issues detected, and the operational parameters remained consistent with the original design.

??Preserved Properties: Shrieve’s alkylbenzene lubricant exhibited remarkable stability, retaining its original properties throughout the trial. There was no evidence of degradation, change in viscosity, total acid number, or oxidation products.

??Controlled Wear: As expected, wear particles initially increased slightly, but they eventually stabilized or decreased over time. The lubricant efficiently protected the moving parts of the compressor, preventing wear and damage.

These interim results provide strong evidence of the outstanding performance offered by Shrieve’s alkylbenzene lubricant in conjunction with ammonia during this extensive field trial.?

Choosing the right lubricant is paramount to safeguarding your refrigeration equipment and optimizing its operational lifespan.

????Protect Your Investment: A proper oil selection can make a world of difference in maintaining the health of your refrigeration system. Shrieve’s alkylbenzene lubricant excels in controlling and minimizing wear and friction between moving parts, extending the life of your equipment. By selecting a high-quality lubricant, you can significantly improve the system's performance and ensure an extended oil drain compared to average oils.

Shrieve takes pride in the very best lubricant solutions that deliver exceptional performance and reliability in various industrial applications. We encourage you to explore the benefits of our alkylbenzene lubricants for your specific maintenance needs, especially when working with ammonia or similar refrigerants.

More about the trial:?

The purpose of the Alhambra Brewing Facility was to measure how efficiently the oil was maintaining its properties with enough performance to protect the compressor. Wear, debris or particles come from mechanical failures. The compressor was well protected.

Another sign of oil deterioration is acidity (chemical attack), and a change in viscosity, with a reduction or increase outside of the specifications. These two will also lead to a lack of protection of the compressor.?

Depending on the working conditions and/or the strength of the oil, it should be drained before its properties are too degraded as to affect the compressor’s performance.?

The normal oil drain interval was one year for mineral oils. After 3 ? years and 14500 hours Shrieve detected that the viscosity was increasing, and it was decided that the useful life of the lubricant was over.?

The extended oil drain interval and the excellent lab results (no wear) fully warrant the unit cost differential between the mineral oil and Shrieve’s synthetic Alkylbenzene.
