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

Allowable Operating Conditions:

Ambient Temperature:

40o F (4oC) to 120oF (50oC) Ambient Relative Humidity:

0% to 90% (non-condensing) Line Voltage: -15% to +10% of Nominal Frequency: 50/60 HZ.

Water Supply Pressure: 20psi – 100 psi.

Maximum Duct Static Pressure: 1” (6000-4)

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.
