Ten best innovative products of the VacuumTechExpo 2015
TwisTorr FS 84
Agilent Technologies and its official distributor Millab introduced a new TwisTorr turbomolecular pump 84 FS with pumping speed of 80 l/s. This model combines patented TwisTorr drag stage technology and Floating Suspension (FS) floating bearing system. The mass and length of the rotor are reduced while maintaining a high performance of the pump. Innovative TwisTorr technology provides high compression ratio for light gases and minimal system footprint. As a result, the power consumption and operating temperature are minimized.
FS system allows to reduce noise and vibration, and ensures optimum performance and high service life of the bearings. The unique bearing and dry lubrication in the TwisTorr 84 FS eliminate oil and maintenance, and permit operation of the pump in any orientation.
GHS VSD+ is Atlas Copco’s new generation of oil-sealed rotary screw vacuum pumps with variable speed drive (VSD).

VAT Series 59 DN16CF
high vacuum leak valve
VAT Series 59 DN16CF is high vacuum leak valve, made by Swiss manufacturer VAT Vakuumventile. The valve is completely made of stainless steel and is designed to control a small gas flows. Metal construction allows case heating up to 300°C, and also provides corrosion protection and resistance to corrosive gases. The valve mechanism is based on a spring-loaded metal membrane that enables the use of the leak valve in the pressure range from 1∙10-10 mbar to 10 bar (abs.). Adjusting the clamping force is carried out by a precise stepper motor controlled by an integrated controller, which can connect to the PC via RS-232. Also a special version of the leak valve with manual drive is developed. Controller with feedback has a port for connecting a vacuum converter.
The innovative feature of leak valve is patented drive force transmission to the spring-loaded membrane in such a way that its sealing occurs only at the elastic deformation. Precision stepper motor via a helical gear accurately transmit the force to the spring, which deforms the membrane, changing the flow area diameter of the leak valve. A stepper motor is controlled by an integrated controller with feedback from a pressure transducer. This design provides smooth adjustment and high reproducibility of small of gas flows to maintain a constant pressure in the system, as well as independence from ambient temperature.
Vacuum system simulating
Tomsk Polytechnic University has developed a set of equipment on the basis of automated vacuum facility for testing protective thin film coatings and materials on impact of the whole spectrum of the main damaging factors in space: vacuum, thermal effects, electron and proton radiation and electromagnetic radiation from the sun. The equipment consists of three parts – a compartment for samples, a compartment for space impact on test samples, and an optical measurements compartment.
The compartment for space impact includes a sun exposure system, a proton irradiation system, an electron beam irradiation system and a temperature control system. Electron beam irradiation system is equipped with two sources, generating particles with energies of 50 keV and 100 keV, the proton irradiation system – with a source of particles with energies up to 50 keV. The density of electron and proton streams are 1012–1016 m-2s-1, the unevenness does not exceed 10%.
The sun exposure system ISO-SKM-1 allows the irradiation of samples in the wavelength range from 200 to 2500 nm. The emission spectrum corresponds to an exo-atmospheric solar irradiance with an error less than 5%. Light spot is a square with a size of 120 × 120 mm. Unevenness of the flux does not exceed 10%.
A system installed in the optical measurement compartment enables calculating spectral reflection and solar radiation absorption coefficient of test material in vacuum in the range of radiation from 250 to 2800 nm.
The innovative feature of this system is the possibility to test in a single cycle space endurance of construction materials.

A unique development is the vacuum vibra-cuvet for fast mixing of powders during sputtering. Vibra-cuvet is installed on substrate holder so that the rotary drive can put it under the selected process source: under ion source to clean the surface of powder particles, under the first magnetron for applying a sublayer, under the second magnetron for deposition of the main material. This allows to create and to study nanomaterials with internal layered structure, which consist of several layers of nanoscale films of different chemical composition and are characterized by a large specific surface with a multiphase anisotropic boundaries between the layers.

NITTIN vacuum elevator furnace for quenching in oil
The range of new vacuum elevator furnaces designed by NITTIN includes four devices. The electric furnaces consists of a vertical vacuum chamber and the working platform placed on three sides of it. Under the platform are located the vacuum system and water cooling system, power and management box, as well as step-down transformer.
The vacuum chamber is water-cooled double-walled housing made of sheet steel. Lined with corundum heating module is mounted in the upper area of the vacuum chamber. In the middle (loading) area is located the charging door. In the lower area (hardening tank) occurs cooling of the charge in the oil. Vacuum system is designed for pumping the working chamber of furnaces up to a residual pressure of 0.133 Pa and consists of a forepump and booster pump.
In the new vacuum electric furnaces the hardening, removal of residues of the oil and vacuum tempering are performed in one cycle. Thus, after heat treatment does not need to remove the allowances, and now processing in vacuum electric furnaces is finishing. So there is no need in the washing equipment, disposal cleaning solution, as well as in additional electric furnace for tempering. Electric furnaces are environmentally friendly equipment, in which there is no emission of reactive gases. This ensures their explosion and fire safety in the operation.
In the socio-economic priorities of Russia a special attention is paid to the development of knowledge-intensive industries with high added value. Such industries include vacuum technology, cryogenics and nanotechnology. There is no doubt that the VacuumTechExpo will contribute to the innovative development of Russian industry.
