The AVDM-250 high-vacuum unit is a structure consisting of a vacuum diffusion oil-vapor pump, a nitrogen trap, a vacuum gate, a frame or a plate. The principle of operation of the AVDM-250 unit is based on the pumping action of a vacuum diffusion steam oil pump. When the AVDM-250 unit is operating, liquid nitrogen is poured into the trap. Condensation of working fluid vapors occurs on the elements of the freezing device cooled with liquid nitrogen. The frame (plate) is designed for mounting the components of the unit. The ends of the wires are connected to a connector mounted on the frame of the AVDM-250 unit.

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

The 3VVN2-50(H) water ring vacuum pump is not intended for use in fire and explosion hazardous industries. The 3VVN2-50(H) 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 3648-053-00218526-2013, designed and manufactured taking into account the requirements of GOST R 52615-2006.

They are designed for carrying out various technological processes at temperatures from 40 to 500 oC, in vacuum up to 1x10−3 mmHg, or in an inert gas of high purity. They are used for drying, light annealing, aging, low and medium tempering in an oxidizing environment, degassing of ferrous and non-ferrous metals (including copper and copper alloys), or any other materials processed under similar conditions. The program setting of heat treatment modes including vacuuming, high purity inert gas intake with repeated vacuuming allows heating in an oxidizing environment with high purity of the surfaces of the processed parts, without scale formation and oxidation.

Pumping out steam-gas mixtures is allowed only when the gas-ballast device is open. The NVR-0,1D vacuum plate-rotary pump is manufactured in the climatic version of UHL 4 (i.e. for moderate and cold climate) according to GOST standard 15150-69, but to be used at ambient temperature and pumped medium 283 K to 308 K (+10˚C to +35˚C). It meets the requirements of technical specifications TU 3648-021-00218526-2001, designed and manufactured taking into account the requirements of GOST R 52615-2006. The quality of electricity must meet the requrimemnts of GOST 53390-2009.

The series is designed for heat treatment according to pre-created programs. The presence of remote control and a number of software options allows you to use the product for long-term heat treatment modes. Vacuum drying cabinets can be used for: - gentle drying of thermo- and oxygen-sensitive substances, such as food, medicinal, cosmetic products; - complete removal of residual moisture from heat-sensitive components with a complex shape, such as components of electronic equipment, jewelry, watches and other precision mechanics; - removal of air when filling the molds with a compound, followed by solidification at a given temperature; - removing air from the product and replacing it with another necessary gas medium; - tempering, annealing or aging of metals with the appropriate processing temperature in a vacuum or protective environment; - drying of products after washing in flammable solvents (special version); - testing of devices under low pressure conditions under various temperature conditions.

The vacuum trap of the condenser type FVC-2/20-X in a chemically resistant design with a capacity of 2 liters is designed to condense aggressive gas vapors on the internal cooled surfaces of the trap, in order to prevent them from entering the pump.

The SNVS-40/5 vacuum drying cabinet with a volume of 40 liters with manual vacuum adjustment is designed for heat treatment of materials at temperatures up to 500 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.

The 3KN-2,5 intake valve includes a nut, the filter is installed in the housing between the two rings. The opening of the inlet valve 3KN-2,5 is carried out when the electromagnet coil is de-energized and the armature returns to its original position under the mechanical pressure of the spring. The closure of the 3KN-2,5 intake valve occurs when an electric voltage of a certain power is applied to the terminals of the coil. The anchor is involved in the shoe, ensuring the closure of the ductal canal.
