Products Description
Overview
The forede® fixed foam proportioner is a device used in fire suppression systems to automatically mix foam concentrate with water at a predetermined, fixed ratio. This mixture is then used to create foam, which is applied to extinguish fires, particularly those involving flammable liquids, oils, or chemicals. Designed to accurately proportion foam concentrate into a pressurised water supply providing an economic means of proportioning for systems requiring a fixed flow rate.

FAQ
Q: What is a fixed foam proportioner?
A fixed foam proportioner is a piece of equipment used in fire suppression systems to mix foam concentrate with water at a predetermined, fixed ratio. This mixture is then directed to fire nozzles or other firefighting equipment to create foam that suppresses fires.
Q: What is the typical foam-water ratio for a fixed foam proportioner?
The foam-to-water ratio can vary depending on the fire hazard being mitigated and the type of foam used. Common ratios range from 1% to 6%, meaning for every 100 liters of water, 1 to 6 liters of foam concentrate are mixed in.
Q: What types of foam concentrates can be used with fixed foam proportioners?
Fixed foam proportioners are typically designed for use with various types of foam concentrates, such as:
Class A foam: Used for ordinary combustibles like wood, paper, and brush.
Class B foam: Used for flammable liquid fires (e.g., oil, gasoline).
Alcohol-resistant foam: Specially designed for fires involving alcohol-based liquids.
Q: How do you determine the correct foam concentrate for a fixed foam proportioner?
The correct foam concentrate is chosen based on the type of fire risk involved (e.g., Class A or Class B fires). Manufacturers usually provide recommendations for foam concentrate and proportioner compatibility. Additionally, the manufacturer may specify certain foam types for particular temperature and environmental conditions.
Q: Are there different types of Fixed foam proportioners?
Balanced pressure proportioners: Foam concentrate is drawn through the system using pressure balance.
Bladder tank proportioners: Use a bladder tank to store foam concentrate and maintain the correct ratio of foam and water.
Inline foam proportioners: Installed in the pipeline between the pump and foam delivery system.
