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 NVSp-35 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 3.5 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 operation of the NVDM-160 diffusion pump is based on the capture and transfer of the pumped gas by a steam jet flowing from the slit gaps of the steam line nozzles towards the outlet flange. The oil reflector of the NVDM-160 diffusion pump is a flange with a cooling tube passing through it, soldered to a cap located in the center of the flange. The NVDM-160 closed-type diffusion pump heater consists of tubular electric heaters fixed in the heater housing. During the operation of the pump, it is necessary to monitor the flow rate and temperature of the cooling water, the level of the working fluid and its temperature. Replacement or refilling of the working fluid depends on the operating mode of the pump (inlet pressure, pumping duration, etc.) and the composition of the pumped medium. Therefore, the time after which the working fluid is replaced or refilled can be from 100 to 1000 or more hours. A large flow rate of the working fluid is observed when the pump is operating in the range of inlet pressures from 6.6×10-2 to 13.3 Pa (from 5×10-4 to 1×10-1 mm Hg). Water at the inlet to the cooling systems of the housing and oil reflector must be supplied with a pressure of no more than 0.5 MPa (5 kgf / cm2) and temperature from plus 40C to plus 250C. The recommended cooling water consumption is 60+10 l/h and is regulated by the outlet water temperature, which should not exceed plus 400C. The water drain should be free (with a jet break). Not allowed: operation of the pump without water cooling, exceeding the maximum exhaust pressure of 33.3 Pa (0.25 mm Hg). The level of the working fluid during operation, at which the parameters of the NVDM-160 pump are provided, must correspond to min 10mm, max 17mm. The volume of the filled working fluid is 0.3 liters
