Q: I just
purchased a plant that has a petroleum machine. The previous owner suggested I
clean the water separator regularly but I really don’t know why. Everything is
working fine right now.
A: There is
always some moisture mixed with solvent. During recovery, water and solvent are
separated in the water separator.
If the water separator is dirty and the
water outlet is clogged, the water will overflow into the distilled solvent
reserve tank. This will happen with a petroleum machine because the petroleum
is lighter than the water. In the water separator, the outlet pipe for
petroleum is located above the water outlet pipe.
If the water outlet is clogged, the
water level will rise and overflow through the solvent outlet causing a mix of
water and solvent in the distilled reserve tank. The solvent used from this
tank will have excessive moisture, which will cause excessive wrinkling and
shrinkage in the garments.
To avoid this type of mishap you must
clean the water separator at least once a week.
