The nitrogen flow trap LAP-100P is designed to protect vacuum pumps from contamination in the form of vapors of resins, oils and adhesives by freezing them on cooled surfaces with the possibility of their removal, and to prevent the penetration of vapors of working fluids of vacuum pumps into the pumped vessel.

The operation of the NVDM-100 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-100 diffusion pump is a cap with a cooling tube soldered onto it with fittings. The open heater of the NVDM-100 diffusion pump is a metal housing with a ceramic base laid in it with a heating element made in the form of a spiral of nichrome wire. 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 should be supplied with a pressure of no more than 0.5 MPa (5 kgf / cm2) and temperature from plus 4˚C to plus 25˚C. The recommended cooling water consumption is 35+5 l/h and is regulated by the outlet water temperature, which should not exceed plus 40˚C. 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 35 Pa (0.263 mm Hg). The level of the working fluid during operation, at which the parameters of the NVDM-100 diffusion pump are provided, must correspond to min 7mm, max 11mm. The volume of the filled working fluid is 0.07/

The working fluid of the pump is water. The use of the 3VVN1-12M(H) 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 engine and destruction of the pump's working parts. The 3VVN1-12M(H) water ring vacuum pump is not intended for use in fire and explosion hazardous industries. The 3VVN1-12M(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.

The SNVS-6.5/3.5 BO vacuum drying cabinet is designed for rapid degassing of compounds and silicones at temperatures up to 350 ° C and an average vacuum of up to 5x10-2 mmHg (Determined by the range of installed sensors). The electric cabinet is made on a stand with wheels. In the upper part there is a vacuum drying chamber and a control system. In the lower part there is a vacuum system. The tight closing of the door is provided by a rotary-eccentric type mechanism and a silicone door seal. In the central part of the door there is an observation window Ø200 mm made of high-temperature quartz glass with a thickness of 20 mm with the illumination of the working chamber installed on it. Coating the cabinet body with powder paint. The control is carried out by a panel software controller located on the door.

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.

Drying cabinet with manual vacuum adjustment on the front panel SNVS-90/3.5 for heat treatment of materials at temperatures up to 350 ° C (optionally up to 500 ° C) Convenient vacuum control on the front panel. Regulation and air intake by manual taps with smooth opening. Such regulation is convenient when processing sensitive materials.

the 2NVR-250D vacuum pump is manufactured in the climatic version of UM 4 (i.e. for moderate 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). Electricity grid must meet the requrimemnts of GOST 13109-97. The 2NVR-250D vacuum rotary vane pump meets the requirements of technical specifications TU 3648-006-00218526-2002. The 2NVR-250D pump is refueled with VACMA OIL 100 power fluid. The level of the working fluid is monitored by the oil indicator, replenishment is needed when the level of the power fluid is below the minimum level of the oil indicator.

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.

The complex includes: VEGA ProVac 1500 turbomolecular high vacuum pump; frequency converter; set of mounting parts; operation manual. For connection to the pre-vacuum pumping system, the pump is equipped with an ISO-KF40 exhaust flange. 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 vertical.

The LP-800 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.
