GTS HUMIDIFIER LX SERIES INSTALLATION, OPERATION, AND MAINTENANCE MANUAL
Product overview
The GTS humidifier LX series burns either natural or propane gas to heat and
boil fill water into steam for humidification. The unit has either one or two
burners that fire into a heat exchanger submerged in a tank of water. When
there is a call for humidity, the burners fire and generate steam until the call for
humidity ends.
UNIVERSAL WATER
DriSteem's GTS humidifier LX series incorporates universal water control for use
with any water type (well, tap, softened, DI or RO water). There is no need to
change control configurations based on water type when ordering equipment
or retrofitting to fit new water sources in the field. The water level control
algorithm monitors water quality and any changes over time to assure the user
of accurate control no matter the type of water that is used.

Supply water guidelines
Supply water quality is an important component
of humidifier reliability and maintenance.
Examples:
• Corrosive water can decrease the service life
of the humidifier.
• Excessive water hardness can increase the
humidifier maintenance requirements.
To maximize humidifier service life and
minimize humidifier maintenance, DriSteem has
established guidelines for supply water. See
Table 8-1:
