leak detections

  • Absolute Vacuum Services Ltd your leak detection specialists carry out an on site a re-evacuation - vacuum dehydration service and a vacuum pumping service of LN2 and cryogenics vessels.  We also offer a (He) Helium leak detection service anywhere in New Zealand with our own portable MSLD helium mass spectrometer leak detector.  Therefore using effective methods of Sniffer Leak Testing and Spray Leak Testing to quickly find leaks.

    Benefits of having your equipment Re-evacuated, vacuum tested, leak tested and vacuum leaks located by AVS:

    • Leak checking can accurately pin point extremely small leaks.
    • The quickest, most cost effective way to find leaks.
    • Find minute vacuum leaks.
    • Non destructive, non-invasive testing, minimal disruption.
    • Determine if your system or equipment is leaking or not.
    • Retain liquid nitrogen and products effectively.
    • Reduce operating costs on product loss.
    • Significant financial savings.
    • Save valuable production time and money.
    • Reduce down time, decrease energy useage.
    • Reduce system failure due to early fault detection.
    • Reduce wear and tear of vacuum pumps.
    • Reduce your carbon footprint.
    • Vacuum check inspections to check integrity of vessels.
    • Protects the environment from dangerous emissions.
    • Leak testing can be carried out with production in operation. .
