Maintenance for Operation with Tap Water or Par-
tially Softened Water
No precise maintenance intervals can be specified because
these always depend on water quality and quantity of steam
generated. It is advisable to adjust the frequency of maintenance
to the specific operational application.
HYGROMATIK recommends to open and check the steam cylin-
der two weeks after commissioning. Ongoing maintenance inter-
vals can be estimated based on the amount and type of residue
found in the steam cylinder.
Blow-Down Cycles
The vaporization process causes mineral (calcium) deposits of
different compositions to settle in the steam cylinder. Part of this
solid build-up is removed through periodic blow-downs and fresh
tap water refills with the aid of the HygroMatik SUPER FLUSH
flushing system.
The SUPER-FLUSH system generates a whirlpool effect in the
strainer basket, intensifying removal of calcium particles during
blow-down.
Water quality
When using tap water, note that cleaning intervals shorten as
the carbonate hardness level in the water increases.
As a gen-
eral rule, it is preferable to operate the unit with fully demineral-
ized water. Operation will not be affected by mineral deposits
and flushing losses will be minimized.
Note: If desired, maintenance intervals can be lengthened by
moderately increasing blow-down rates. Please consult Hygro-
Matik.
