PAC Cold Filter Plugging Point Application
Cold Filter Plugging Point (CFPP) testing is one of the most critical analyses for diesel and biodiesel fuels intended for cold climates. It determines the lowest temperature at which fuel will still pass through a standardized filtration device under defined cooling conditions. This measurement ensures that fuels can perform reliably without clogging filters in engines and distribution systems during winter operation.
PAC’s CFPP testing solution provides fully automated analysis that meets EN 116 and IP 309 methods, ensuring international compliance. By simulating real-world cold weather conditions, it provides valuable insight into the operability of diesel fuels and helps producers guarantee performance across global markets.
The instrument employs precise cooling control and vacuum-assisted filtration to detect the temperature at which fuel no longer flows through the filter within a specified time. This eliminates human error, increases repeatability, and ensures results that are directly comparable across laboratories and facilities.
With a wide measuring range down to –80 °C, the system covers conventional diesel, biodiesel blends, and specialty fuels, making it highly versatile for both research and commercial testing. Rapid cooling cycles and automated detection reduce analysis time while maintaining accuracy and consistency.
The CFPP parameter is particularly important for vehicle manufacturers and fuel suppliers in cold regions, as a fuel with inadequate cold flow properties can lead to filter plugging, fuel starvation, and severe engine malfunctions. Reliable testing ensures safety and operability in extreme weather conditions.
In addition to operational safety, CFPP testing is a valuable tool for product development and formulation optimization. Refineries and additive manufacturers rely on it to evaluate the effectiveness of cold flow improvers and to validate product performance under harsh winter scenarios.
The instrument requires only a small sample volume and operates with low user intervention, making it highly efficient for routine quality control and high-throughput testing environments. Its robust automation reduces operator workload and ensures compliance without compromise.
By delivering precision, speed, and compliance, PAC’s CFPP testing capability empowers the fuel industry to maintain reliable fuel quality worldwide, ensuring that diesel products meet the challenges of cold climates while safeguarding both equipment and end-users.
