1.GENERAL INFORMATION
For the safe use of the FORMECO distillation units it is obligatory to read the general Distillation Guide as well as
this manual.
1.1.
Distillation unit DT for non flammable solvents
The machines indicated with the first letters DT , are equipped with a splash-water proof electrical part (IP44) and can
be used only for the distillation of non-flammable solvents.
1.2.
Distillation unit RS for flammable solvents
The machines indicated with the first letters RS , are equipped with an explosion proof electrical part (According to
ATEX ), and can be used in ZONE 1 and ZONE 2 and are suitable to distil both flammable and non-
flammable solvents .
1.3.
Operating principle
Exploiting the principle of simple distillation, the unit separates the contaminations (such as resins, paints, pigments,
ink, oil, grease, etc.) from the original solvent, which, once recycled directly into a tank, can then immediately be used
again. The contamination remains on the bottom of the boiler and can easily be unloaded at the end of the cycle.
The boiling of the polluted solvent takes place in a boiler surrounded by a cavity space containing diathermic oil heated
by an electric element. The vapour is conveyed to an air cooled condenser and transformed back into a liquid state; the
condensed solvent is collected in a tank. The characteristics of the solvents will in no way be altered by the process if the
instructions are followed carefully. The number of distillations can hence be repeated indefinitely.
The unit allows the recovery and re-use of solvents with a boiling point between 50 and 180 °C. Using a vacuum unit
(optional) solvents with a boiling point up to 220 °C can be recycled.
1.4.
Operation
The operation cycle is fully automatic, the intervention of the operator is only necessary for loading the solvent to be
distilled (1), setting temperature and distillation time (2) and unloading of the residues (3-4).
1.5.
Safety features
The distillation unit operates at atmospheric pressure.
Cases of abnormal high temperature increase or faulty operation of the condenser are signalled and the machine stops
automatically.
