Z-Inline Inductor
for fixed Installation
|
|
Proportion ratio 3% or 6% |
|
Constant proportioning rate caused by balance valve, works with back pressure up to 2 bar |
|
| 1. General Description |
| The purpose of the inline inductors Z2 and Z4 is to draw foam concentrate from a storage container and to admix it into the water stream at a fixed percentage. Both proportioners are available in either a 3% or 6% setting. A balance valve ensures correct proportioning even during sudden changes in flow rate and/or pressure. Due to the working principle of the inductor a pressure drop of approximately 33% is caused over the inductor. |
| 2. Recommended Foam Concentrates |
Protein 3%, 6%
Fluoroprotein 3%, 6%
AFFF 1%, 3%, 6%, ARC 3x6, 3x3
Detergent Foam |
| 3. Application |
| Z proportioners are used predominantly in fire trucks, but can also be installed in aircraft hangars, on ships, tank storage facilities or filling stations. |
| 4. Operation |
| The proportioner is built into the system as shown in diagram 1. The proportioner is working according to the injector principle. The water flow through the injector creates a vacuum thereby drawing a predetermined amount of foam concentrate into the inductor where it is admixed into the water stream. |
