Condenser are efficiently applied to the solvents evaporating during the drying process. Using condensers substantially increases the capacity of the vacuum system, in particular during the initial phase of the drying process, when large amount of solvents are being evaporated.

In the example shown two individual cooling circuits are shown. Depending on the requirements brine is used for very volatile solvents whereas cooling water is used for less volatile solvents.

Liquid ring vacuum pumps are commonly used to handle "Wet" gas mixture (i.e. mixture containing condensable vapors). The moisture present in such mixtures can wash away the lubricating oil in traditional "dry" oil lubricuted pumps, possibly leading to premature failure.

A liquid ring vacuum pump is a very versatile machine. It can handle "Wet" loads & has no metal to metal contact. It also acts line a direct contact condenser, it can absorb the Heat generated by the compression, friction & Condensation of the incoming gas & it will absorb & wash out any contaminants entrained in the gas.

With two stage liquid ring vacuum pump, ring liquid vessel, post condenser and ejector.

Vacuum pump (1) with dual three stage claw mechanism, booster pump (2) for increased suction capacity flame arrestir (3), post condenser (4) and condensate receiver (5).
