4.2 The steam cylinder and the SC-System
The SC-System is a patented self-cleaning system developed
by NORDMANN for its electrode steam-bath generators. Because the
minerals are kept in suspension, there is little accumulation of
deposits on the floor of the cylinder. The loose minerals are flushed away
during normal drainage operations. The steam cylinder’s service
life is considerably lengthened and the time spent on maintenance is reduced.
The serviceable life of a steam cylinder is dependent on both the quality of
the water supply and the unit’s actual operating hours.
Lifetime of a steam cylinder at 100% steam output
A regular check of the steam cylinder ensures trouble-free operation.
If the steam-bath generator indicates U1 (see page 16), it can still be run
for a few days before the steam cylinder needs to be replaced.
We recommend that you keep a spare cylinder in stock for each unit.
