Vapor Degreasing is probably the most effective method for
cleaning grease, and oils off of all types of metals, It basically
works by vaporizing a chlorinated solvent by a heat source,
and condensing it over cold oily metal. As the solvent cools, it
washes all oils off the metal surface.
Our unit is a 5' x 12' x 16' deep rectangular tank. A two ton
capacity hoist is used to lower the metal basket into the
vapor zone.
There are 3 standard chlorinated degreaser type solvents:
trichloroethylene, methylene chloride and perchloroethylene.
We use perchloroethylene (perc). The perc is in a reservoir
at the bottom on the degreasing tank and is brought to a boil
at 240 degrees, causing it to vaporise. The cleaning space,
or vapor zone, is just above the boiling solvent.
To confine solvent vapor to the tank and prevent vapor loss
to the atmosphere, a refrigerant or water cooled external
jacket or internal coils are located above the vapor zone.
Clean vapor condensate is collected in a trough, passed
through a water separator to remove excess moisture, and
returned to the boiling sump.
A metal basket filled with dirty parts is lowered in the vapor
degreasing zone. The parts are not immersed in solvent.
Instead the vapor made by the boiling solvent encompasses
the parts completely and removes the oils. The oils, now
diluted into the condensing liquid, will drip back into the
boiling solvent below. There is a manual spray wand, which is
sprayed under the cooling coils, directly on hard-to-remove
oil.
Near the top of the either type of degreaser is a set of
cooling coils, that catches the vapor before it escapes from
the unit. It cools and condenses it back to its liquid form and
flows it back to a clean condensate tank and finally it goes
back to the boil sump or the rinse tank. Since oil and grease
boil at a higher temperature than for chlorinated solvents, the
vapor caused by the now oil mixed solvent, only vaporizes
the clean chlorinated solvent not the dirty oil, if the
temperature settings are correctly set. Therefore only clean
vapor is used to clean parts.
