Details on Technical Data for Hydrants
Information on the technical data dialog for Hydrants.
A hydrant can be drawn and connected like a component (WC, wash stand, etc.).
You are here:
According to DIN 1988-6, within a potable water system, only hydrants are permitted as self-support devices.
They must be defined with a calculation flow rate of a maximum of 2 x 24 l/min with a minimum flow pressure of 2000 hPa. Wall hydrants are to be installed with a securing combination. This combination is made up of a backflow prevention mechanism and pipe ventilation. The drawn pipe should be kept as short as possible. In the event of a greater firefighting water requirement, a separate firefighting network should be planned.
Name
Specifies the name of the component. You can modify the name. Clicking 
restores the default setting.
Consideration
Use the drop-down list to specify how the hydrant should be included in the calculation.
| Option | Description |
|---|---|
| Consider minimum flow pressure. | The geodetic pressure loss is calculated up to the hydrant. |
| Consideration of minimum flow pressure and fire water flow rate | Allows you to consider not only the minimum flow pressure but also the fire water flow rate in the design. |
| do not consider | The hydrant is not included in the calculation. |
Minimum flow pressure: Enter the minimum flow pressure in hPa. The consumers are generally predefined with expedient values.
Flow rate fire water: In case of Consideration of minimum flow pressure and fire water flow rate, specify the fire water flow rate to be considered in the dimensioning in l/s.
Min. nominal diameter: In this field you define the minimum size of the wall hydrant. In the calculation, it is thus not possible to select a smaller dimension.
Reset: If you changed the values manually, you can use the Reset button to reset the values to the default data.
