Helium can not be substituted as a test gas. Increasing Helium demand is making Helium recovery necessary. Helium recovery is in average amortising itself within 6-9 months.More then one test system can be connected to a helium recovery.Excessive amounts of Helium is still wasted into atmosphere which is an unnecessary on cost.
RecoverIT is normally used in conjunction with Noleks automated leak testing systems in industrial application areas, where helium is used to verify leak tightness of manufactured and assembled components. They can also be used with other leak testing systems and in other applications where helium can be recovered for reuse or recycling.
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.
There are 2 basic techniques: High vacuum testing allows the leak test threshold to be set as low as 1 × 10 -12 mbar.l.sec -1, or used to get helium leaks down to 1 × 10 - 6 mbar.l.sec - 1 . For reference, 1 cubic millimeter per second is approximately 1 × 10 -3 mbar.l.sec -1 . or 1cc is about 1mbar liters per second.
The amount of helium that can be recovered will depend on the leak test process settings, namely: The vacuum level that can be achieved before injecting the helium tracer gas. It is important to note that the vacuum level determines the attainable helium concentration during the test.
Perhaps the biggest factor that makes helium an ideal tracer gas for leak testing is its low atmospheric concentration (5 ppm). This low concentration allows designers to configure testing equipment that can detect leaks below 10 -9 atmcc/sec in vacuum applications and below 1 x 10 -6 atmcc/sec in sniffing or atmospheric applications.
Gas Analyzer. Once the helium has been reclaimed and repressurized, the gas analyzer measures the percentage of recovered helium in that primary tank to determine the amount of helium to be added to achieve the desired mix. If a reclaim system is, say, 90% efficient, it means it is able to recover 90% back for reuse and we only need to add 10% ...
The recovered gas is controlled and concentration is measured enabling mixing it up to the correct concentration for reuse in the measurement process again and again. The Helium recovery system is possible to install in existing machines and can also be shared among multiple leak detection machines. The recovery system is controlled by RxSCADA.
The Helium Recovery Systems offered consists of ASME coded pressure tanks, a set of compressor (s), gas analyzer, microprocessor controls, and all necessary valving, gas regulation, and piping. Greater test pressures mean greater helium usage, which is why many companies use the VIC Helium Recovery System (HRS) to reclaim up to 98% of Helium usage.
Helium Recovery is suitable for high productivity leak testing operations where a large quantity of helium is used. It involves recovering helium from the unit under test (UUT), checking and possibly reinstating its concentration, and compressing it back to the required leak test pressure.

most helium recovery or reclaiming systems function on the following principles: receive the used helium into a low pressure receiver tank as it vents from the test part at the end of the test, re-pressurize the gas, filter and cool the gas, measure concentration and add new helium gas to compensate for losses, and return the gas to the leak test …
