Humidifiers | Steam Humidifiers Humidifiers CARNES MICROPROCESSOR CONTROLLED STEAM HUMIDIFIERS use ordinary untreated tap water and convert it to mineral free steam for humidity control in commercial, industrial, institutional and residential applications.
FRONT PANEL DISPLAYS & CONTROLS The display on the front panel of the humidifier cabinet contains the “On-Off-Drain” switch, the LCD True Touchscreen display and the “Fill”, “Drain” and “High Water” LED’s. “DRAIN” LED The DRAIN LED is a red light illuminated when the Drain Valve is activated. An activated Drain Valve allows water to drain from the humidifier. An analogous indicator, and a description of its operation, is offered in the “Component Activity” menu.
Humidifiers | Displays & Internal Controls Humidifiers Required” page for more information. 5. Maize — 8. Steam (orange) - Explains the status of the “Steam” indicator light. The humidifier will only produce steam if the “Steam” indicator light is green. The indicator will be brown when the On/Off/Drain switch is in the “Off” position.
The Control humidistat, which provides the Control Demand, is normally the humidistat in the room being humidified. It is either installed in the room itself or the return air duct. The High-Limit humidistat, which provides the Hi-Limit Demand, is a safe-guard humidistat installed in the supply duct roughly 10-15 feet past the distribution tube. This humidistat is usually set to a high level (8090%), and will shut down the humidifier if the humidity gets too high in the supply duct.

Humidifiers Humidifiers | Displays & Internal Controls Setpoint Timeout – Boil Down Timer – This page is where the Setpoint Timeout value is set. The maximum amount of time allowed for the unit to reach setpoint during a fill sequence is designated by the Setpoint Timeout. Its default value is 30 minutes, but can be set as high as 255 minutes.
Humidifiers | Displays & Internal Controls Humidifiers Calibration Password – The help pages consist of maize color buttons labeled with questions. When a button is pressed, information will be given answering and/or giving information about the subject in question. A basic help page consists of text and/or diagrams to help the user through basic problems. This page is where the Humidifier Unit Code, the four digit number identifying the humidifier, is programmed into the unit.
APPLICATIONS OPERATION COMFORT Upon a signal from external controls the circuit board opens a fill solenoid valve, allowing water to flow across an air gap into a standpipe. The standpipe provides a column of water to be fed into the cylinder using gravity. The air gap prevents back flow into the water supply and prevents the cylinder from becoming a pressure vessel. The steam cylinder operates at a pressure of approximately 1/2 psi.
Humidifiers | System Design Consideration Humidifiers LOCATING THE HUMIDIFIER Locate the humidifier cabinet level and plumb on a surface as close to the steam distributor as possible at a convenient height for servicing. Allow 1” or more on the sides for ventilation and 16” from the bottom of the unit to the floor to allow for drain connections. Allow 14” in front of cabinet for door opening (Figure B).
STEAM DISTRIBUTOR PIPE LOCATION (Continued) Steam distributor pipes must be located on a plumb surface so condensate that forms will run back into the return line. The pipe should be located in the center of the duct to insure even distribution of steam into the airstream. A minimum clearance of 4” must be maintained between the top of the duct and the distributor pipe. The steam distributor pipes are usually located in the supply duct downstream of the fan.

CONDENSATION PROTECTION A third device may be desirable to provide condensation protection in the duct system. A high limit humidistat may be installed ten (10) feet downstream from the steam distributor pipe. This humidistat is normally set to 90-95% RH and opens the circuit if the humidity level in the duct exceeds the set-point.

Humidifiers | Accessories Humidifiers WALL HUMIDISTAT, PROPORTIONAL CONTROL DUCT HUMIDISTAT, PROPORTIONAL CONTROL Model HXHAM Model HXHAN The Model HXHAM is a wall-mounted, microprocessorcontrolled humidistat solution for cutting edge humidity control. The HXHAM employs a backlit LCD module, which displays both the ambient temperature and humidity of the surrounding air.
DUCT HUMIDISTAT, ON-OFF CONTROL Model HXHAB This duct mounted humidistat mounts in the return air duct to provide control of the humidifier. The control should be located in the duct where it will be affected by normal air flow. The maximum temperature at the nylon element must not exceed 125°F. The control can be mounted in any position, but where possible locate it on the side of the duct to make the set-point adjustment easily accessible. Scale range is 15%-50% RH Differential is 4%-6% non-adjustable.
Humidifiers | Accessories Humidifiers AIR FLOW SWITCH PRESSURE DIFFERENTIAL TYPE Model HXAAE Air flow in the duct may be sensed by using this differential pressure switch. The differential in pressure between the interior of the duct and ambient when air is moving in the duct closes a micro switch allowing the humidifier to operate. Air pressure differential as low as .07 w.g. and as high as 12.0 w.g. may be sensed with one model. The switch may be mounted with tubing connecting to the duct.

CARNES STEAM HUMIDIFIERS use a microprocessor, digital display and LED’s to provide superior operating and diagnostic functions to simplify troubleshooting and reduce maintenance costs. OPERATION Upon a signal from a humidistat the circuit board opens a fill solenoid valve, allowing water to flow across a 1” air gap into a standpipe. The air gap prevents back flow to the water supply and prevents the cylinder from becoming a pressure vessel.

Humidifiers Humidifiers | Steam Manifold SHORT ABSORPTION MANIFOLDS FOR STEAM HUMIDIFIERS Carnes Steam Manifolds are designed to provide dry steam with rapid absorption in the duct air stream. It achieves this by distributing steam evenly across the face of the duct. The distance needed for absorption is dependent on a number of factors, some of which are air velocity, steam volume, air temperature and characteristics of air flow in the duct.
Humidifiers | Steam Manifolds Humidifiers CARNES STEAM MANIFOLDS are available in standard sizes from 18” x 12” through 72” x 48” in two inch increments. Additional special sizes are available. Table 3 Table 1 Air Pressure Loss, “w.g.” 500 fpm .02 750 fpm .
CARNES STEAM MANIFOLDS with strong galvanized flanged frames are factory assembled to reduce installation costs. LOCATION OF MANIFOLD The manifold is usually located in the supply duct downstream of the fan, heating coil, cooling coil and/or filter. When installed in packaged units, the manifold is to be mounted just downstream of the fan discharge. Figure A The non-wetting dimension is the distance necessary to prevent condensation on any obstruction downstream from the manifold.
