Use
The EFS 8241 test bench is part of a new generation of test benches designed for calibration or endurance tests of diesel injection devices.
It can drive up to 8 injectors with 8 EMI2 units.
It takes up very little floor space, while incorporating all the necessary control devices and offering some very advantageous features for the user :
Large work surface.
Easy access via the two glassed-in doors.
Equipment modularity.
High pin rotation speed, precise electronic regulation.
High drive torque.
Easily accessible, high-capacity oil tank.
Permanent oil circulation, ensuring a stable temperature regulation.
Very fast fluid temperature regulation.
Easy maintenance.
Safety
Active protection of the installation :
Automatic door locking with controlled door opening.
Pin motor monitoring.
Test fluid temperature monitoring.
Primary tank low-level detection.
Waste oil tank high-level detection.
Two emergency punch-stop buttons.
Automatic closure of water circuit (by electro-valve).
Technical features
Tubular steel structure fitted with removable closing panels.
Thermoset epoxy coating.
Standard colour = RAL 7035.
Other RAL colours according to customer specifications.
