Helium Charge Recovery 4.5MPa Nitrogen Gross Leak Detection Equipment 8 min / pc
Helium Charge and Recovery System with Nitrogen Gross Leak Detection System
The system is used for helium charge recovery and leak detection of air conditioning systems. Firstly, a large leak tightness test is performed on the workpiece to be inspected by using a nitrogen pressure of 4.5 MPa, then 2.0MPa helium is charged into workpiece, and then helium mass spectrometer with sniffer gun is applied to the workpiece for fine leak detection, after that helium inside of workpiece is recovered. The system can determine the qualified and unqualified workpiece, and the leak point of the unqualified product.

≥98% |
|
Equipment size |
2.0*1.5*1.8m |
|
Equipment noise |
≤70 decibels (with silencer in the exhaust process) |
Advantages:
The equipment adopts 55bar high-pressure helium gas storage to reduce the volume of the helium gas tank. The high-pressure tank is installed inside the equipment, which makes the equipment compact and has a small footprint.
In order to protect the customer's clean inspection workshop from helium pollution, all joints of the equipment are subjected to a leak detection process to ensure that the entire equipment will not leak.
Equipped with computer and scan code gun, the internal program is associated with production system of production line.
Adopts INFICON P3000 leak detector, the highest leak detection rate is 1.0E-8Pa.m3/sec.
The system is controlled by PLC, operated on touch screen.
