NABLEND Series offer a range of Blender for the preparation of PRF dedicated to Octane and Cetane Measurement by CFR engine.
In accordance with ASTM D613, D2699, D2700 and corresponding international standards.

Main caracteristics
Automatic blending by weight involves the use of a computer to read the electronic balance, to control the dosing pumps and to communicate with the operator.
After the required volume and octane number is given by the operator, the computer will make the necessary calculations and control the blending process until the reference fuel is made.
The results can be stored in a database and certificates can be printed for all blends.
The method is very comfortable and needs no special attention from the operator.
The blends will be highly accurate because all possible human error is eliminated.
The difference in the temperature of the blending components will have no effect on the final octane number as the weight of the components does not change significantly with temperature.
If the error introduced by the balance is less then 0.1g the accuracy of the blend will be better than 0.02 ON in the range of 40-100 ON and a volume of 400 ml or higher.
If the cabinet of the automatic blending unit is vented a laboratory hood is not necessary.

Additional informations
NABLEND 887XA is an automatic blending unit for ASTM reference and check fuels used in conjunction with WAUKESHA CFR engines.
Using the built in touch screen computer the operator must simply enter the targeted octane / cetane number and the targeted amount in ml of the reference or check fuel required and the computer will automatically prepare the blend according to the ASTM tables.
The blending unit contains three, five, or six containers of 10 liters each, for Iso-Octane, N-Heptane, Toluene, 80/20 blend, N-Cetane, and Heptamethylnonane (HMN), and three, five, or six dosing pumps. The blending components are pumped one by one into a vessel, located on an electronic balance.
When all components are added, using the data collected from the balance, the real octane / cetane number is calculated, stored in a database and a blend certificate is printed.
Compared to the targeted octane / cetane number, the real octane or cetane number may differ slightly (+/- 0.01 ON / CN), but will reflect precisely the actual composition of the blend.
