DRI-STEEM GTS Humidifier Installation, Operation, and Maintenance Manual • Page 77
Capacity notes
• At sea level, 402 kJ are required to raise the temperature of one
kilogram of water from 4 °C to 100 °C.
• An additional 2257 kJ are required to change the state of one
kilogram of 100 °C water to vapor.
• Another factor to consider is condensation steam loss from hoses
and tubes. Use the following steam loss guidelines:
– Vapor hose: 0.22 kg/m/h
– Insulated pipe: 0.07 kg/m/h
– Dispersion tubes: 0.7 kg/m/h
LP gas
All models operate at rated kW input.
Operating characteristics
• Unit is capable of operating in ambient conditions of 5 °C to
40 °C.
• Unit is capable of operating in ambient conditions between 30%
RH and 95% RH (noncondensing).
• NOx class 5
Gas supply pressure
• 20 or 25 mbar for natural gas (depending on gas group), and 30,
37 or 50 mbar for propane gas (depending on gas group)
PMS (all units)
• 7.0 bar
Electric supply
• 230V, 667W to 2415W (see data plate)
Max inlet water temperature
• 90 °C

Note:
* The maximum steam capacities listed may be as much as 10% lower than the given values due to local variations in the Wobbe index of G20 and G25 gases.
Caution! Gas pressure to the
humidifier controls must never exceed
6 kPa (60 mbar) or the gas valve will
become damaged and require replacement.
Immediately install a DN6 pipe thread
plugged tapping, accessible for test gauge
connection, upstream of the gas supply
connection to the appliance.
