FireDos Foam Proportioners
Reliable and Made-to-Last
The FireDos proportioner runs solely on extinguishing water flow. This greatly reduces electrical installation costs. Owners also avoid environmental permitting, maintenance, and fuel requirements of engine-driven proportioners. These units are ideal for locations with frequent long-term power outages from disasters. The purely mechanical construction means FireDos proportioners are reliable and provide a long service life.

Optimum Extinguishing Performance due to Constant Proportioning Rate
The water motor drives a specially developed proportioning pump. This pump injects foam concentrate into the extinguishing water. There is a direct linear correlation between the water flow rate and the water motor’s revolutions. The proportioning pump is directly connected to the water motor via a coupling. As the water flow through the water motor increases, more foam agent is injected. This way, the volume ratio, referred to as the “proportioning rate,” remains constant, allowing optimal proportioning as water flow rates change.
Low Pressure Loss
Only a small portion of the pressure in the extinguishing water line is consumed in driving the water motor and the proportioning pump.
Engineered for ease
Quick to Install. Easy to Operate.
FireDos proportioners are installed rapidly and easy to commission. All components are supplied as compact units.
Seamless Integration
No valves need to be opened to initiate foam flow due to the positive displacement pump design. As such, the foam proportioner activates immediately upon the start of foam solution flow. Furthermore, the foam proportioning pump delivers only what is required.
Intuitive User Interface
The foam concentrate is stored in an atmospheric tank that can be refilled whenever needed, enabling firefighting with no time limits due to foam concentrate storage capacity. Switching to a different foam concentrate at the same proportioning rate is possible at any time, as the proportioner is suitable for all foam concentrate types.
Suitable for all Foam Concentrate Types
FireDos proportioners are compact, with the latest generation characterized by lower weight and reduced dimensions. Only high-quality components and materials were involved in the development of this technology.
Our Products in Action
As of 2020, more than 13,000 FireDos proportioners have been successfully placed into service worldwide. These units serve in various industries such as logistics, chemical, and oil & gas. FireDos proportioners can be found anywhere where flammable liquids or solids are produced, transported, or stored. This includes the automotive, aviation, and marine industries.
FireDos Proportioners
Eco-Friendly and Cost-Effective Testing
FireDos proportioners can be fully tested without discharging foam solution to the ground and with no foam concentrate consumed. This applies to both acceptance and annual testing and greatly reduces the environmental concerns and long-term costs associated with testing.
