Hannover Fair COMVAC - 24th April - 28th April 2017

From 24 to 28 April 2017, the Hanover Fair COMVAC will again be
the meeting place for the international compressed air and vacuum industry.
Leybold, vacuum specialist located in Cologne, Germany, will also use this stage
to present its vacuum portfolio to the specialist audience:
  • The innovation for speed and load lock applications: The DRYVAC
    PowerBoost pump-down system.
  • The VACUBE screw vacuum pump and the CLAWVAC dry-running claw pump are the latest news for applications in the rough vacuum range.
  • New in the high vacuum range are the two new product families TURBOVACi and iX, the newly designed diffusion pump line DIJ, as well as the TiTanTM ion getter and titanium sublimation pumps..

The DRYVAC PowerBoost pump-down system - the first intelligent pump system
With DRYVAC PowerBoost, Leybold presents the fastest and most energy efficient pumpdown
system on the market. This system also offers several cost reduction potentials.
DRYVAC PowerBoost solutions offer 60 ─ 120% more suction speed than previous
generations of pump-down system.
As a result, the number of required load lock pumping systems can be reduced by up to
40%. Of course, similar results can be achieved for already existing production systems
that now operate with only one pumping system.
With the reduction of the required systems, the operating costs decrease. Furthermore,
installation costs and floor space are also considerably reduced. The intelligent software
of the PowerBoost system automatically detects the cycle length of the pumping process
and optimally adapts to the conditions for the shortest pumpdown times and highest noise

Oil-sealed screwtype vacuum pump VACUBE
The VACUBE screw vacuum pump has been developed with the aim of providing highperformance
support for industrial applications with rough operating pressures. Their
compact size allows easy installation and system integration. The smallest model of the
pump family claims the footprint of a standard pallet.

Compared to other products of the same performance class, the pumps of the VACUBE
series consume significantly less energy and offer an extremely high suction capacity. In
addition, the pumps operate very quietly - two important aspects in modern workplaces,
which have to work energetically efficiently and have to provide optimal working
conditions for employees. The low energy requirement is due, among other things, to the
integrated operating program with control and monitoring functions for VACUBE. The
"intelligence" and the simple "plug-and-play" installation predestine this type of pump for
use as a central vacuum system.

VACUBE can be equipped with an energy recovery option. This enables the recovery of
up to 75% of the electrical power and significantly increases the efficiency if the hot water
generated in the process can be used in the process. The user saves operating costs and
optimizes the use of energy resources. The integrated highly effective oil return system
prevents the contamination of the pump environment and the working area by lubricants
and process particles.Equipped with these features, the VACUBE vacuum all-rounder fits into processes and
applications of very different industries:

  • Food processing and packaging
  • Central vacuum systems in laboratories or drying plants
  • Transport of material (transport vacuum)
  • Assemblers (e.g., battery, capacitor)
  • Pipeline drying
  • Wood processing

Claw pump family CLAWVAC
As a further fore vacuum pump, Leybold introduces the CLAWVAC dry vacuum pump. In
addition to the applications already mentioned for the VACUBE range, the CLAWVAC is
also suitable for drying and sterilization processes and environmental technology
applications. Furthermore, it is used in extruder degassing.

The uncomplicated handling of the robust pump can also be traced back to its functional
principle: In the CLAWVAC, a claw rotor pair rotates completely contactless and wearfree
in the cylinder. The CLAWVAC differentiates itself from conventional claw pumps
mainly through its material selection. Stainless steel rotors as well as the corrosionresistant
coated vacuum chamber also prove themselves under very harsh process
conditions and contribute to a reliable operation.

The compression room of the CLAWVAC allows a simple disassembly and cleaning by
the end user. This includes the removal of the rotor pair and its easy reassembly without
a need for complicated timing adjustment. This is a favorable feature for customers
running dirty applications, which so far needed to ask for cleaning by the manufacturer’s
staff. This design principle also enables a quick exchange of individual components. In
sum, the set-up ensures minimum standstill times and low service costs.

The ECODRY plus was developed to match the requirements for systems such as mass
spectrometers and electron microscopes. It is also suitable for large-scale accelerators
due to the absence of dust or oil contamination. It offers a high degree of comfort, suction
power and flexibility. The pump family is available in the sizes 40 plus and 65 plus, as
used in analytical or research laboratories. This pump class is positioned exactly in the
transition area between small laboratory equipment and large machines.

However, the most important innovation is undoubtedly the reduction of the noise level.
At an average of 52 dB (A), the sound level of the ECODRY plus is below a conversation
at room volume. In every day operation and compared to the relevant competitive
products of its class, the pump, which is designed for ergonomic working environments,
yields the lowest noise emissions.

TURBOVAC - for efficiency in analytics
Leybold will also present the innovative pumps of the product line TURBOVAC i /iX 90 to
450 l / s with integrated drive electronics at the Hanover Fair COMVAC. The iX version
incorporates a vacuum system control unit for plug and play pump system operation.
Leybold has developed a tailor-made vacuum system for the analysis market as well as
R&D and industrial applications based on this turbo-molecular pump range. The series is
suitable for ultra-high vacuum applications and easy installation in compact pumping
system solutions. In analysis cycles with increased sensitivity, it guarantees an
uninterrupted running of the devices with minimal vibrations and noises. This is especially
important for this market: In class comparison, the pumping speed for light gases is
significantly higher and compression has improved many times over the previous pump

While the 350 i and 450 i are intended for processes with small fore vacuum pumps, the
TURBOVAC T 350 i and T 450 i models have a classic rotor design for high gas loads.
The positive consequences are faster acceleration times and a higher insensitivity to
particles. All variants have in common that the unique oil-free hybrid bearing concept
(permanent magnetic bearing and life-lubricated ball bearing) offers an excellent
reliability. In addition, it eliminates the need for oil changes and enables a problem-free
and fast pumping of the pump at full speed.

Öl Diffusionspumpen DIJ Serie
The Leybold high-vacuum DIJ diffusion pumps are a further addition to the portfolio. Due
to their additional ejector stage, these new diffusion pumps achieve a high and stable gas
throughput even in the 10-2 to 10-3 mbar range. The innovative heating concept ensures
optimized energy transfer as well as optimized thermal insulation for lowest energy
consumption. An optimized housing design with connections for both ANSI and ISO
components as well as various electrical connection variants facilitates flexible worldwide
use of the pumps. Of course, these new diffusion pumps are also available with the
already proven "Energy Control Unit", offering energy savings of > 50% compared to
unregulated standard pumps, depending on the process cycle. The DIJ line of pumps will
become first choice in the all areas of the vacuum industry.

Ion Sputter and titanium sublimation pumps
In applications that require pure, hydrocarbon-free and reliable high and ultra high
vacuum, the TiTan® ion pumps and titanium sublimation pumps (TSP) developed and
manufactured by Gamma Vacuum in the USA, have many advantages. Gasses are
bonded in the ion-getter and titanium sublimation pumps by means of sorption.

This energy-saving type of vacuum generation does not cause vibrations or noises and
offers a uniquely low power consumption. It makes them well suited for many research,
industrial and medical applications and in a wide range of analytical instruments.

The titanium sublimation pumps (TSP) can be combined with ion pumps or used
independently. Combined with an ion pump, they quickly reach a low final pressure. All
TSP components are bakeable up to 400 ° C, like the ion getter pumps.

The Gamma vacuum ion pumps are designed for operating times of 45,000 to 50,000
operating hours at 1x10-6 mbar – longer even at lower pressures. They are capable of
generating pressures below 1x10-10 mbar. Ion pumps are used in many sizes and
configurations. They can be operated in any position and due to their different sizes in
low and tall profile variants even in limited space conditions.

With all Leybold components, customers can choose from a wide range of configurations
and sizes, depending on the requirements. In addition, Leybold advises and manages the
users' application experience throughout the entire process - from the definition of the
system requirements to the tailor-made after-sales support. Project-specific, economic
and production-related experiences are part of the project support, with the aim of
developing future-proof vacuum systems.

The Leybold team looks forward to a professional exchange at the Hannover Fair
