Enhancing Low-Temperature Flow Performance Testing – Fully Automatic, High Precision, Dual-Station
In the testing of diesel, biodiesel, blended fuels, and petroleum products with strict low-temperature flow requirements, Cold Filter Plugging Point (CFPP) is a key indicator for evaluating fuel low-temperature flow performance and ensuring reliable engine start-up in cold conditions. The DFYF-137Z Fully Automatic CFPP Tester adopts industrial-grade PLC control and high-precision sensing technology to achieve fully automated CFPP determination. It is widely used in refineries, quality inspection centers, fuel storage and transportation companies, and third-party laboratories.
1. Wide Temperature Range with Precise Control
The instrument supports a temperature measurement range from -70°C to 0°C with a temperature control accuracy of ±0.1°C, meeting the CFPP analysis requirements of diesel and various low-temperature fuels under different environmental conditions.
2. Dual Cold Traps for Independent Operation – Double Efficiency
Equipped with 2 test cold traps that can operate independently, allowing simultaneous testing of two samples.
Each cold trap is fully equipped with an automatic detection and vacuum control system, operating without mutual interference – significantly improving laboratory testing efficiency.
3. Core Automation Functions
3.1 Automatic Pipette Filling Detection
Built-in sensors monitor the pipette filling process in real time, automatically drawing 20 mL ± 0.2 mL of sample (with a marking at 20 mL), ensuring consistent and accurate sample volume for each test.
3.2 Pipette Bottom Position Positioning
Another sensor automatically locates the bottom position of the pipette with a positioning accuracy of 85 mm ± 4 mm, providing an accurate reference for the filtration process.
3.3 Electronic Vacuum Regulator
Throughout the entire test, the vacuum regulator automatically maintains a stable negative pressure of 2 kPa ± 0.02 kPa, eliminating manual intervention and ensuring consistent filtration conditions.
3.4 High-Precision Time Measurement
The built-in time measurement device has an accuracy of 0.2 seconds, with an accuracy of 0.10% over 10 minutes, meeting the stringent time recording requirements of standard test methods.
4. Intelligent Control and Data Management
4.1 Industrial PLC Controller
The instrument adopts an industrial-grade PLC controller, offering stable operation and strong anti-interference capability, suitable for continuous operation in both laboratory and industrial environments.
4.2 7-Inch Color Touch Screen
Equipped with a 7-inch color touch screen featuring touch-button operation, the user-friendly interface makes parameter setting, test start-up, and result review quick and convenient.
4.3 Dual-Sample Independent Storage and Historical Data Query
Test results for 2 samples are stored independently without mixing.
Can store up to 10,000 sets of historical data, supporting conditional queries for quality traceability and data analysis.
4.4 Optional Micro Thermal Printer
After the test is completed, the instrument can automatically print results (printer optional), facilitating record keeping and archiving.
