Product overview
SUPPLY WATER
There are benefi ts and trade-offs to consider when the application allows a
choice between hard and softened water:
Hard water: The benefi t of hard water is less frequent draining and fi lling
than with softened water, which results in better energy and water effi ciency
and more consistent steam output. However, cylinder replacement could
be more frequent with hard water, because hard water scale coats the
electrodes. The harder the water, the more frequent the need for a new
cylinder.
Softened water may be used in the XT series electrode humidifi er. However,
softened water ions stay in solution to much higher concentrations than
hard water ions. The result can be more frequent draining and fi lling, which
results in less energy and water effi ciency, and less consistent steam output.
While softened water can reduce scale build-up in the cylinder, it can also
shorten cylinder electrode life.
