Title: Humidifiers for Every Application
1Humidifiers for Every Application
2Pressure Steam Humidifiers Designed to deliver
Reliable humidity from facility steam boilers
3What is LiveSteam?
- LiveSteam humidifiers utilizes existing facility
boiler steam for humidification in one of two
ways - Directly introduce boiler steam into the duct
work for humidification - Utilize boiler steam as the energy source to
generate clean steam for humidification
4Why Use LiveSteam?
- A source of central steam is
- available
- Inexpensive
- Energy efficient

32Troubleshooting
33Distributor Discharging Water?
- Ensure T is from top of main
- Verify steam trap operation
- Ensure steam trap orifice is not clogged
- Ensure proper amount of steam traps
- Ensure pipe and traps are sized correctly
34Water Leaks from Tube Adapters?
- O-ring damaged or missing
- Connection not tight
- Distributor not supported properly at other end
resulting in stress on the tube adapter and
o-ring
35Over Humidifying?
- Incorrect valve size
- Steam pressure too high
- Exceeded max close off pressure of the actuator
- Controls not calibrated or malfunctioning
- Steam valve stuck open
- Damaged seat in the valve
- Spring tension on actuator too light or loose
36Under Humidifying?
- Incorrect valve size
- Insufficient amount of steam (undersized
boiler) - Controls out of calibration
- Header size too small
- Steam pressure too low or fluctuating
37Humidity Swings?
- Doors/Windows etc. opening and closing
- Location of controls (ie. High limit too close
to distribution) - Fluctuating steam supply pressure to the unit
38Spitting During Start-Up?
- Temperature switch not installed or not
functioning - Incorrect valve size
- Boiler carrying too much condensate
39Condensate in Duct?
- Duct too cold
- Distributors too close to duct wall
- Higher air velocity required (300 ft/min
minimum) - Absorption distance calculations are incorrect
- Incorrect valve size
- Malfunctioning or lack of safety high limit

55Why Insulate? SAM-e Insulated Option
- Wasted energy - Lost heat is lost money
- Wasted Water (Condensate)
- Air stream heat gain
- Low humidifier output
- Low system efficiency
56Benefits of Insulation SAM-e Insulated Option
- Thermal Resistance,
- R 0.66 ft-ºF-hr/Btu
- 70 condensate reduction
- 120F max surface temperature
- Reduce heat gain
- Improved efficiency

64Troubleshooting
65Distributor Discharging Water?
- Verify steam trap operation
- Ensure steam trap orifice is not clogged
- Ensure proper amount of steam traps
- Ensure pipe and traps are sized correctly
66Leaking Around Tube Seals?
- Verify seal is fully inserted
- Check for physical damage
- Verify that stopper plate is in place
- Verify chemicals added to boiler
67Steam Condensing on Duct Wall?
- Verify duct psychometrics
- Check for unusual flow patterns
