Vacuum resistance furnaces are necessary for heating products before pressure treatment, for sintering, degassing, quenching, annealing, soldering and chemical-technological processes. Such furnaces among all the variety of thermal equipment are considered the most environmentally friendly – heat treatment is carried out at t up to +2500 ° C in a purified vacuum. Under certain conditions, vacuum furnaces are used to work with neutral gases. The outer part of the furnace is made of stainless steel and is cooled by liquid. The inner part of the working chamber, where the heat treatment of materials is carried out, is made of an alloy of molybdenum and tungsten. The components are characterized by a low inertia force, reduced gas separation. The settings are available on the control panel, where the instruments, automatic and manual control switches are located. At every enterprise of the electronic industry, nuclear power, an explosion-proof vacuum resistance furnace is needed. The same applies to areas where various products undergo heat treatment at the stage of production and preparation for use.

The complex includes: single-flow turbomolecular vacuum pump VGTN-150; frequency converter; set of mounting parts; operation manual. For connecting to the pre-vacuum pumping system, the pump is equipped with an ISO-KF25 exhaust flange. If necessary, it can be upgraded with an ISO-KF16 flange for purging the pump with inert gas. Pump cooling is combined. Based on the operating conditions, the complex can work both with forced air cooling and with water cooling. The working orientation in space is arbitrary. One of the key features of the pump is that a breakthrough of the atmosphere is possible. This has become possible due to the production of a turbine from a solid billet and a special, rigid design of the bearing assembly.

The LP-1000 flow water trap is installed on the inlet flange of the diffusion pump and is designed to reduce the flow of working fluid vapors into the pumped volume by condensing them on the cooled elements of the freezing device.

The ISO-KF connection (DIN 28 403 and ISO 2861) allows quick installation and replacement of components in vacuum systems. The connection consists of two symmetrical ISO-KF flanges (1), a centering ring with an O-ring seal (2) and a quick-release clamp (3). High-vacuum ISO-KF connections can be mounted without using a tool by simply turning the nut of the quick-release clamp.

Claw clamps in the groove of the base plate (galvanized steel) for ISO-K.

The SNVS-50/3.5 vacuum drying cabinet with a volume of 50 liters with manual vacuum adjustment is designed for heat treatment of materials at temperatures up to 350 with air access and in a vacuum controlled by manual valves. Thanks to modern temperature control, it demonstrates excellent performance of heat treatment modes. The measurement system complies with Russian standards and has certificates of entry into the SI State Register. Design for heat treatment in production and clean laboratories. The cabinet can be equipped with a software control device with an automatic timer and a wide selection of additional options.

Horizontal drying vacuum chamber SNVS-512/0.8-I2-2B is designed for rapid vacuum drying of heat-sensitive elements with hidden cavities and containing a large volume of moisture. The use of a plate heat exchanger allows you to condense up to 10 liters of liquid (in the standard version) and prevent it from entering the pump. The presence of a fan significantly reduces the initial heating time of the part. The shelves are fixed on roller guides and can be freely extended. The shelf is designed for a distributed load of up to 250 kg.

The use of a 2VVN1-12M(H) water-ring vacuum pump for pumping out water-gas mixtures is allowed only if the bulk of the water is separated and discharged at the pump entrance. Failure to comply with this requirement may lead to unacceptable overload of the electric motor and destruction of the working parts of the 2VVN1-12M(N) pump. The 2VVN1-12M(N) vacuum water ring pump is manufactured in the climatic version of UHL 4 and O4 (i.e. for moderate and cold climate) according to GOST standard 15150-69, meets the requirements of technical specifications TU 3648-015-00218526-2000, designed and manufactured taking into account the requirements of GOST R 52615-2006. The quality of electricity must meet the requrimemnts of GOST 32144-2013.

ConFlat (CF) standard connections are used to ensure the connection of components of vacuum systems operating in the field of high and ultra-high vacuum.

The MU-800 flanged enlarged oil reflector performs the function of an oil reflector, is installed instead of a standard oil reflector in ND pumps and has an additional number of cooled screens to capture oil return flow vapors.

ConFlat (CF) standard connections are used to ensure the connection of components of vacuum systems operating in the field of high and ultra-high vacuum.

High-temperature furnaces are capable of heating materials up to 1700 degrees. The scope of their application covers the heat treatment of various materials in an inert medium or vacuum. TULA-TERM furnaces are used for heat treatment of plastics, ceramics, metals, alloys, lacquers and other materials. The equipment allows sintering, annealing, soldering, quenching, drying, burning and molding. In industry, our installations are most often used for quenching parts and sintering hard alloys.
