Vacuum Chamber Leak Testing Equipment For Evaporator/Condenser With
2 Chamber
Product information:
The leak detection systems are controlled by a state of the art PLC
especially configured to comply with the customer’s process
requirements. The PLC allows automatic operation including visual
and audio signs, alarms, emergency buttons and automatic data
storage. It also allows manual control of the system and
modification of process parameters and recipes through the touch
screen.
Vacuum helium leak tests can be performed using an “inside-out” or
“outside-in” method. In an inside-out vacuum leak test, a part is
placed in a sealed chamber and secured. A vacuum pump is then used
to remove all the atmosphere from the chamber and part. After a
sufficient vacuum is reached, the test cycle begins. Leak Testing Equipment
