Management of Scale and Chloride Levels
As the humidifier produces steam, minerals dissolved in the water begin to concentrate in the tank over
time. The amount of dissolved minerals and the chloride levels need to be carefully controlled so they
do not affect the efficiency and service life of components. Hardness of water may cause foaming and
contribute to scale build-up in the humidifier tank and float chamber, and chlorides increase the risk
of stress corrosion cracking in stainless steel components of the humidifier. All of these contribute to
reduced efficiency, and increased amount of service and related maintenance costs.
IMPORTANT!
Component failures due to water quality outside the recommended ranges (refer to
) are not covered by warranty.
The Condair
GS humidifier periodically drains water from the tank to reduce the concentration of dis
-
solved minerals that accumulate during long-term operation. This is achieved in two ways – through a
partial blowdown and a full tank blowdown (FTBD).
In a partial blowdown, a certain amount of water (determined by the Blowdown Rate setting) is drained
from the tank and replaced with fresh water, thus lowering the concentration levels. In a FTBD, the en
-
tire tank is drained when a certain number of weighted hours (determined by the FTBD Interval setting)
have elapsed, then refilled with fresh water. Weighted hours is defined as the hours equivalent to a unit
operating at 100% output.
The humidifier is shipped with a default Blowdown Rate of 25% for the partial blowdown, and FTBD Interval
of 100 hours for FTBD. These settings ensure that concentration of dissolved minerals is minimized for
all water conditions. However, they can be adjusted in the control software once water conditions are
known for your site – refer to
