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 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.

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 working condition of the ND-400(R) 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-400(R) diffusion pump is a maximum of 5 liters, a minimum of 3.3 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 heaters in the ND-400(R) 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-400(P) diffusion pump to 320°C, the temperature sensor must give the command to automatically turn off the heaters. The subsequent activation of the pump heaters should not be automatic and should be performed 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 250 l/h, for the oil reflector it is 40 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 vacuum trap of the condenser type FVC-2/70 with a capacity of 2 liters is designed for condensation of vapors of non-aggressive gases on the internal cooled surfaces of the trap, at temperatures up to -70 C.

This electric vacuum drying cabinet is designed for drying and heating various materials in air and in vacuum at temperatures up to 250 ° C. A viewing window Ø 160 mm is installed in the door. The illumination of the working chamber is provided from the outside. An additional, independent security system is installed in the cabinet, interrupting the supply of the cabinet when operating temperatures exceed.

The LP-500 flow-through 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 LA-400 nitrogen filling 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 elements of the freezing device cooled with liquid nitrogen.

The AVDM-160 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-160 unit is based on the pumping action of a vacuum diffusion steam oil pump. When the AVDM-160 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 attached to the connector fixed on the plate of the AVDM-160 units.

The vacuum drying electric cabinet is designed for drying and heating various materials in an air environment and high vacuum (GOST 5197-85) at temperatures up to 350 ° C.
