Vacuum Oven
It removes the source of contamination. For example, heating metals to high temperature causes rapid oxidation in regular ovens which is undesirable. It reduces the heat loss which is caused by convection In chemical process industries like food, pharmaceutical, agricultural, textile, paper & pulp etc. drying is an essential unit operation to remove the moisture from various substances to get a solid finished product .Vacuum drying is generally used for the drying of those substances which are hygroscopic and heat .

vacuum brazing furnaces
Reasons to Braze under Vacuum The following reasons support the use of brazing under vacuum: Calibrated use of alloy with magnesium (4045, 4044, 4104, 4004) to prevent excessive Mg sublimation in the vacuum chamber High final vacuum due to high capacity pumping systems (cryogenic pump + diffusion pumps), which produce a low oxygen atmosphere Rapid transition of the load temperature during the heating phase from 520 °C (starting temperature for Mg sublimation) to 605610 °C thanks to high power furnaces, a feature that prevents an oxidized layer (Al2O3) from reforming on the surface of the piece newly reduced to Al Suitable fixing systems of the individual heat exchanger prevent the piece from collapsing or deforming Uniform load temperature (± 3 °C at 605 °C) is achieved through accurate control of the output power and by distributing the heating zones Cleanliness of the components No emission of contaminated substances into the atmosphere Controlled cooling of the walls and other elements of the furnace with heated water (80 °C) to prevent atmospheric water vapor from condensing during loading and unloading process

high vacuum systems
The performance of all vacuum systems is governed by the fundamental relationship Q=SP (gas load in torr literssec. = pumping speed in literssec. x pressure in torr).1 It is obvious, when we look at the equation, that the pressure will be lower if either pumping speed is increased or the gas load is decreased. The pumping speed of a pump can be easily checked in the manufacturer’s specifications and the effective pumping speed at the chamber can be calculated fairly easily. The total gas load, though, is a little more elusive. This is due to the fact that each chamber design or process will have its own specific gas loads that will combine to make up the total that the pump is required to deal with. Although it’s important to assess and control these gas loads in the design phase, it’s also important to know and understand them in an already existing and working system. In an overall sense, gas loads can be divided according to their sources as either volume gas or wall gas. Volume gas is the easiest to understand and deal with. This is nothing more than the amount of gas trapped within the chamber volume at the onset of the pumpdown process. Volume calculations are easy to do in either the design phase or on an existing system. The importance of the system’s volume applies only to the roughing segment of the pumpdown process. The manufacturers of roughing pumps usually provide a simple means of calculating pumpdown performance based on volume and pumping speed. This makes it a fairly simple matter to design in the right sized roughing pump and roughing line to achieve the expected or specified pumpdown performance. Once the pumpdown proceeds past roughly 1 torr, though, the volume begins to slowly lose importance. By the time the total pressure falls to 1 millitorr or so, the gas in the original volume is almost gone. In the low10-4 torr range, volume gas no longer plays a part in the to
