As North American distributor since 2019, Cannistraro partners with the industry leader FireDos to deliver the highest performance fire protection systems available for fire protection clients across the globe. With FireDos foam proportioners, Cannistraro’s experts engineer, install, and maintain high-efficiency fire protection and special hazards systems that deliver foam fire suppressants precisely when and where you need them in the event of an emergency.

Why FireDos?

As part of our commitment to providing the highest-quality mechanical construction solutions available today, all of our services are self-performing, and we fabricate almost all of your mechanical infrastructure at our on-site fabrication facility. However, we realize that we can’t do it all, so when it comes to supplementing our capabilities, we only partner with and source parts from the manufacturers we trust. Cannistraro partners with FireDos for proportioners because they share our dedication to designing fire protection infrastructure that’s responding to the challenges of the 21st century.

The proportioners FireDos manufacturers offer benefits like:


Because FireDos proportioners are hydraulically optimized, they can reduce pressure loss by up to 25%. That results in higher water flow rates and more efficient delivery of extinguishing agents to put fires out faster. At the same time, since the water motor is a closed system, you don’t have to worry about water loss during operation.


FireDos proportioners are compatible with all types of foam suppressants, including high viscosity, alcohol-resistant, and fluorine-free foam agents. No matter which foam agent you choose to use, a FireDos proportioner can deliver that foam more efficiently than any other product on the market. And with adjustable proportioning rates, we can simultaneously optimize flow rates for efficient performance at your facility.


Every square foot of your facility is valuable, and we understand the importance of making the most of each square foot. FireDos proportioners feature a sturdy, compact design that takes up no more space than necessary. Plus, the water motors and proportioning equipment is driven entirely by the flow of water, so no electricity or backup power supply is required.
