  • Leybold designs new TURBOVAC IR model series for R&D, medical and industrial applications


    Robust, individual, clean, service-friendly

    With the TURBOVAC IR variants, vacuum manufacturer Leybold is launching a new, complete turbomolecular pump series, technologically derived from the proven TURBOVAC IR family. “The IR models replace the former TURBOVAC Classic Line pumps and meet, for example, the requirements of our high-end research customers – such as the major research institutes CERN or DESY,” summarizes the responsible product manager, Petr Lastovicka.

    Very high radiation tolerances and flexible remote operation
    Accordingly, the TURBOVAC IR was designed for flexible remote operation from 3 meters to
    distances of one kilometre. In all aspects the products were also designed to resist the
    challenges which are present in environments with high to very high ionizing radiation. “For this,
    we offer special cable lengths of up to 200 meters, and also the option for the users to use their
    own cables,” explains product manager Petr Lastovicka. According to Lastovicka, the IR models
    were developed using the existing material knowledge of the research community: As a result,
    the materials they contain have radiation tolerances of up to 1 million grays (Gy).

    Combination with ion and NEG pumps

    In combination with the ion getter and non-evaporable getter pumps, so called ultra-high
    vacuum pumps, “These attributes set them apart from standard market models, which are
    meeting the market requirements but not specifically those needed for the particular conditions
    encountered in research centers,” says Petr Lastovicka. This is different with the TURBOVAC IR
    product series: on the one hand, they were developed for the special requirements regarding
    cable length and radiation tolerance. “In addition, we can offer the TURBOVAC IR pumps
    combined with our ion pumps and NEG pumps, which other suppliers cannot offer as a
    package,” adds Lastovicka. TURBOVAC IR fits perfectly well in the TURBOVAC IR eco systems
    as other products such as accessories or the software LeyAssist can be utilized as well.

    Requirements of the high-energy physics market
    The bottom line is that the new IR models are designed to meet the technical requirements of
    the high-energy physics market. This makes them predestined for applications such as
    synchrotrons (particle accelerators), cyclotrons (circular accelerators), linear accelerators and
    free-electron lasers. “In these areas, users can remove the electronics and place them in areas
    where they are not exposed to radiation,” explains Petr Lastovicka.

    Absolute purity
    Another elementary condition in these application areas is the absolute purity of the pump: this
    core requirement is fulfilled by the oil-free operation of the bearing system of the new
    TURBOVAC IR series. The TURBOVAC IR also supports all relevant communication options of
    the TURBOVAC IR, USB, 15-pin digital I/O and all serial and fieldbus options of the
    TURBO.DRIVE 500e. Another advantage: The integrated, new TURBO.DRIVE controller
    automatically recognizes the pump model and immediately adjusts to the specific operating

    Sizes 1350 and 1450 will follow in the third quarter of 2022
    The TURBOVAC IR range completely covers all existing members of the TURBOVAC IR family with
    pumping speeds from 90 to 950 l/s. In parallel, Leybold will successively expand the
    accessories range of supporting controllers and cable options to meet customer needs for
    additional cable lengths and intelligent solutions. The intelligent Controller TURBO.DRIVE
    500eC has been released in April and the TURBOVAC IR sizes 1350 and 1450 will follow in the
    third quarter of 2022 together with the more powerful controller option to realize even longer
    cable lengths.
