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.

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

Size of DN: 10,16,20,25,32,40. Centering rings (aluminum / stainless steel) with a circular O-ring.

The AVDM-100 high-vacuum unit consists 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-100 unit is based on the pumping action of a vacuum diffusion steam oil pump. When the AVDM-100 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 wiring wires are connected to the connector fixed on the plate of the AVDM-100 unit.

The drying cabinet with manual vacuum adjustment SNVS-90/5 (or SNVS-4,3.4,3.4.9/5) is designed for heat treatment of materials at temperatures up to 500 ° C with air access and in a vacuum controlled by manual valves.

Vacuum drying cabinet model SNVS-155/3,5-I2-RT-N with a volume of 155 liters of special design with a chamber width of 630 mm., with manual vacuum adjustment from the back of the chamber for heat treatment at temperatures up to 350 degrees.

The working condition of the ND-500 diffusion pump depends on the temperature of the working fluid in the pump boiler. During the initial filling, it is recommended to fill the maximum volume of the working fluid. Working fluid is "VACMA OIL 500" vacuum oil (under technical specifications TU 19.20.29-061-00218526-2019). The total amount of working fluid in the ND-500 diffusion pump is a maximum of 5.5 liters, a minimum of 4 liters. The viewing window for visual inspection of the working fluid has marks of its maximum and minimum amounts. During normal operation of the pump, the level of the working fluid practically does not change.The temperature of the working fluid when the pump is operating at the maximum residual pressure is about 240°C to 255°C. It is recommended to monitor the operation of the heaters in the ND-500 diffusion pump using one temperature sensor. The temperature sensor must be installed in a special radiator socket above the heater. If there is a loss of working fluid and an increase in the temperature of the radiators of the ND-500 diffusion pump up to 320°C, the temperature sensor should give the command to automatically turn off the heaters. The subsequent activation of the pump heaters should not be automatic and should be carried out only after cooling the system. Water at the inlet to the cooling systems of the housing and the oil reflector must be supplied with a pressure of 0.3 MPa (3 kgf/cm2) to 0.5 MPa (5 kgf/cm2) and a temperature of plus 4 ° C to plus 25 ° C. The recommended cooling water consumption for the housing is 500 l/h, for the oil reflector it is 50 l / h. It is regulated by the outlet water temperature, which should not exceed plus 40°C. The water drain should be free (with a jet break). The required speed of action of pre-vacuum pumps at a pressure of 26 Pa (0.2 mm Hg.st) in the outlet section of the ND-500 diffusion pump should be at least 42 l/s. To reduce the losses of the working fluid of the ND-500 diffusion pump at pressures (1·10-1- 1) Pa [(7,5·10-4- 7,5·10-3) mmHg] it is recommended to install an additional LP-500 flow-through water trap on the outlet flange.

The NVSp-4 dry vacuum spiral pump can operate continuously at an inlet pressure of no more than 10 kPa (75 mm Hg), pumping out one or more sealed vessels with a total volume of no more than 0.7 m3 from atmospheric to residual pressure during the day. Pumping of vessels of the specified volume with leakage is allowed, but the leakage should not cause an increase in pressure at the pump inlet of more than 10 kPa (75 mm Hg).

The 2ZVE-250R vacuum shutter with electromechanical drive equipped with 250mm conditional passages is designed to overlap vacuum systems in the range of operating pressures from 1x10-6 to 1.07x105 Pa (0.75x10–8 to 800 mm Hg). The 2ZVE-250R shutter is pendulum-type. The 23VE-250R shutter is manufactured in the climatic version UHL (i.e. for moderate and cold climate) and O (i.e. general) 4 according to GOST standard 15150-69. The working environment is air and non–aggressive gases. It is not intended for use in fire and explosive hazardous industries. The 23VE-250R shutter meets the requirements of technical specifications TU 3648-040-00218526-2003. According to the method of protecting a person from electric shock, the gate belongs to Class I electrical equipment according to GOST 12.2.007.0-75.
