GNI0003H PP 1
Loop Trainer
GNI0003H PP 2
Reason for Study
• Because the Loop Trainer gives instructors the capability to control water flow, pressure and temperature, it can be used to simulate almost any scenario in real time.
GNI0003H PP 3
Reason for Study
• The Loop Trainer can also be used to simulate special conditions, such as radiation control areas and to train employees on clearance and tagging procedures as well as maintenance and operation tasks.
