The forede® PHF/C portable foam inductors can be placed near a portable pump or hydrant outlet, minimising manpower requirements and leaving the firefighter to concentrate on effective application of the foam to control the fire situation. It offers a simple accurate method of proportioning when the water supply pressure is reasonably high. Each proportioner is designed for a set water pressure. However, higher or lower inlet pressure results in an increase or decrease in water flow with a change in proportioning.

Q1: Can the in - line foam inductor be used with a foam concentrate that has a high freezing point in cold climates?
A: Using a foam concentrate with a high freezing point in cold climates can pose issues. The concentrate may solidify, preventing proper induction and foam generation. It's advisable to use a foam concentrate specifically formulated for cold climates with a lower freezing point. Additionally, consider insulating the inductor and associated lines to prevent freezing.
2.Q2: How does the in - line foam inductor affect the pressure drop in the fire suppression system?
A: The in - line foam inductor does cause a certain amount of pressure drop in the system due to its internal structure and the process of drawing in foam concentrate. However, it's designed to minimize this pressure drop and ensure that the overall system pressure remains within acceptable limits for proper operation of downstream components like nozzles or sprinklers. The exact pressure drop depends on factors such as flow rate and the inductor's design.
3.Q3: Can the in - line foam inductor be installed in a system with a high - velocity water supply?
A: The in - line foam inductor can be installed in a system with a high - velocity water supply, but it's important to ensure that the velocity is within the inductor's specified operating range. High - velocity water can affect the inductor's ability to accurately proportion the foam concentrate. If the velocity is too high, it may be necessary to install flow - control devices upstream to regulate the water flow and ensure proper foam induction.
4.Q4: What is the impact of sediment or debris in the water supply on the in - line foam inductor?
A: Sediment or debris in the water supply can clog the in - line foam inductor's internal passages, disrupting the flow of water and the induction of foam concentrate. This can lead to inaccurate foam solution ratios or even complete blockage. Installing a suitable strainer or filter upstream of the inductor can help prevent sediment and debris from entering and causing problems. Regular cleaning and maintenance are also crucial to remove any accumulated particles.
5.Q5: Can the in - line foam inductor be used in a foam - water sprinkler system with multiple zones?
A: Yes, the in - line foam inductor can be used in a foam - water sprinkler system with multiple zones. It can be installed in the main water supply line before the branching to different zones. However, it's important to ensure that the flow rate and pressure requirements of each zone are met and that the inductor can handle the combined flow. Additionally, proper balancing of the system may be required to ensure consistent foam solution distribution across all zones.
6.Q6: How do I calibrate the in - line foam inductor to ensure accurate foam solution proportioning?
A: Calibration procedures vary by manufacturer. Generally, it involves verifying the water flow rate using appropriate flow - measurement devices and adjusting the inductor's proportioning mechanism according to the manufacturer's instructions. Some inductors may have adjustable components that can be fine - tuned to achieve the desired foam solution ratio. It's often recommended to perform calibration during installation and periodically as part of maintenance to account for any wear or changes in the system.
7.Q7: Can the in - line foam inductor be used in a system where the foam concentrate is stored in a non - pressurized container?
A: The in - line foam inductor can be used with a non - pressurized foam concentrate container. However, the design of the connection between the container and the inductor needs to ensure that there is a proper siphoning action to draw the concentrate into the water stream. Gravity - fed systems or those with a properly designed suction line can work effectively. It's important to ensure that the container is located at an appropriate height and that the suction line is free from blockages.
8.Q8: What is the role of the coupling standards (e.g., British - BS336, German - Storz) in the installation of the in - line foam inductor?
A: The coupling standards determine how the in - line foam inductor connects to the existing piping system. These standards ensure a secure and leak - free connection. Different regions or systems may use specific coupling types, and using the correct one guarantees compatibility. It also simplifies installation and maintenance, as standard - sized tools and replacement parts can be used. Additionally, proper coupling ensures that the inductor can handle the system's pressure and flow requirements.
9.Q9: Can the in - line foam inductor be used in a system that requires rapid activation during a fire emergency?
A: Yes, the in - line foam inductor is designed to operate quickly once the water flow is initiated. As water starts flowing through the system, the inductor immediately begins to draw in and mix the foam concentrate. However, the overall system's response time also depends on other factors like the activation mechanism of the water supply (e.g., sprinkler heads opening, valve activation). Regular testing and maintenance of the entire system, including the inductor, are necessary to ensure rapid and reliable activation during an emergency.
10.Q10: How does the in - line foam inductor's performance change over time with repeated use?
A: With repeated use, the in - line foam inductor's performance can be affected by factors like wear and tear on its internal components, corrosion due to exposure to foam concentrate and water, and potential blockages from sediment or debris. Regular maintenance, such as cleaning, lubricating moving parts, and inspecting for damage, can help mitigate these effects and maintain the inductor's performance. Over an extended period, some components may need replacement to ensure continued accurate foam solution proportioning.
