Engineering and Application 
 
The Herrmidifier 6000 Series Steam Humidifiers can be 
applied in a variety of applications. The simplest 
application is to utilize the model with the built-in blower 
package (6000-1,2). The steam generated by the unit is 
distributed into the conditioned space by the built-in 
blower package (Figure 1). 
 
Alternatively, steam generated by the "6000" unit can be 
discharged directly into the system ductwork (6000-3,4). 
In this application, a steam pipe is preferably installed in 
the system ductwork at least five (5) feet downstream of 
the supply air blower. There should be no obstructions 
within the first five- (5) feet downstream of the steam 
distributor as shown in Figure 2. An air-proving switch 
and high limit humidistat are provided for better system 
control in ducted applications. If the heating system  
 
 
 
 
operates for short periods at a time and the desired 
relative humidity level is not achieved, the humidifier can 
be wired to turn on the blower when there is a call for 
humidity. In this case an air-proving switch will not be 
necessary, but the high limit humidistat should still be 
utilized. 
 
NOTE 
The steam distributor pipe is inherently sloped to
return the condensate to the humidifier. 
 
The steam piping from the humidifier to the steam
distributor should have an 8% slope (1” per foot) up
to the steam distributor. Steam hose may be used up
to a maximum of 20’ between the unit and the steam
distributor.  The hose provided with the unit is 10’
long.  There can be no sags in the steam hose, as
this will create a trap and will produce back pressure
in the steam cylinder and may blow condensate in
the duct.
