Helium Leak Testing Equipment For Condenser And Evaporator

The Helium Leak Detection System is specially designed for leak test Condenser, Evaporator, Automobile radiator, Engine cooler, switch gears, and it is the most efficient industrial-scale Automatic Leak Testing Equipments for Heat Exchangers in Market.

The system is able to run the following tests:

• Leak detection with pressure decay method to find Gross Leaks.
• Helium test with mass spectrometer to find Fine leaks.

Features:

• PLC control, touch screen display
• All automatic leak testing with over all leak test
• Non operator dependent
• Back ground suppression technology, ensure precise testing
• Automatic digital pass/Fail indication.
• Ensure operation reliability

The chamber helium leak test system proposed has the totally automatic cycle with manual load and unload of the tested piece.

The Test Cycle can be described in the following way:

• Manual load of the tested piece in the Test Chamber.
• Closure of the Chamber.
• Evacuation of the Chamber to a value of vacuum suitable for Leak Test with Mass Spectrometer. During the evacuation of the Chamber, the system will run the following Tests on the tested piece:
• Pressure decay to reveal Gross Leaks;
• Tested piece evacuation;
• Reaching a vacuum value suitable for transfer, that is to put the mass spectrometer in communication with the Test Chamber.
• Reading of background, which is the residual Helium in the Test Chamber.
• Pressurization of tested piece with Helium.
• Leak test with Mass Spectrometer.
• Ventilation of the Test Chamber (return to atmospheric pressure),
• Helium Recovery from tested piece.
• Opening of the Chamber
• Manual unloads of tested piece.
