PBBT-2 PET Bottle Burst Tester for keg is a specialized test equipment for testing the internal pressure resistance of PET kegs. It’s designed in accordance with the three general using test methods which are commonly used for PET containers. Users can choose the test method basing on their in-house requirement. The PBBT-2 is capable to test the capacity of resilience under certain pressure or the rupture test of the PET kegs.

Through the reproduction of the pressurization, the process has been linearized and it increases to the predetermined point or the point of bursting.

After selecting the test program, the cycle will start automatically depending on the settings. The touch screen displays the pressure value in real time and record the maximum pressure and burst pressure.

Optional part water recycling system could provide way of saving water and avoiding the unsteady pressure of tap water which may influence a normal test.

Additional booster could be chosen. It may help the PBBT-2 free of high pressure source.

Fill ramp mode:

Under this mode, the PET kegs are pressurized rapidly to the initially preset pressure and maintained for a given time (for example 13 seconds). Then continue to increase the pressure with a speed like 0.7 bar/s (speed is settable) until the outbreak of the bottle or reaching the max pressure or volume. Preset parameter includes: initial pressure, Hold time and ramp speed.


Burst mode:

Under this mode, PET keg will be pressurized rapidly to the initially preset pressure and maintained for a predefined period. Preset parameter includes: initial pressure, Hold time and Expansion limit.


Custom mode:

Under this mode, user is able to create the pressure curve to meet the particular conditions of control. Users can define the pressure curve by steps, after the adjustment is made, the corresponding curve will
