Rotaflow’s water mist fire suppression systems are high-performance, developed for effective fire control, lower water use and improved safety. These green solutions are a viable alternative to standard fire suppression technologies that may be used across a variety of industries.
Rotaflow offers customised water mist fire suppression systems for commercial, industrial and high-risk settings.
Rotaflow designs and installs high pressure water mist systems for industrial facilities, turbines, data centres, machinery spaces and oil & gas operations. These systems are fast to suppress fires and consume far less water than standard sprinkler systems, minimising equipment damage and downtime.
Low pressure water mist systems are perfect for commercial buildings, businesses, hotels and retrofit applications. Rotaflow offers tailored solutions to improve fire prevention efficacy, reduce water storage requirements and minimise interruption to existing infrastructure.
Rotaflow carries out extensive site assessments to establish fire risks, dangers of occupancy and operational requirements. The team reviews each site carefully, to offer the best water mist suppression solution for long-term safety and compliance.
All water mist systems are designed to meet project needs and appropriate standards such as NFPA 750, FM Approved, UL 2167 and CAN/ULC-S1001. Rotaflow’s in-house engineering team guarantees reliable system integration and efficient fire suppression performance.
Rotaflow controls the entire installation and commissioning procedure with all components installed and tested and validated for optimal operation. The team is responsible for system integration, functional testing and final inspections to guarantee that systems are ready for handover.
Routine inspections, testing, maintenance and system upgrades provide long-term reliability and compliance. Rotaflow continues to support water mist systems to ensure their continuous effectiveness and to adapt to new safety and code requirements.

Water mist systems use significantly less water, reducing the risk of water damage while providing superior fire suppression efficiency. Unlike traditional sprinklers, they work by rapidly cooling flames and removing heat energy while also displacing oxygen, making them highly effective for environments with sensitive equipment.
No. Water mist systems use a low-volume water supply, often requiring only a small pump or cylinder-based system. This makes them suitable for areas where large water reserves or traditional piping systems are not feasible.
NFPA 750 defines systems by the pressure of the distribution piping. Low-pressure systems are those systems operating at 175 psi (12.1 bar) or less. Intermediate-pressure systems are those systems operating at pressures over 175 psi but less than 500 psi (34.5 bar). High-pressure systems are those systems operating at 500 psi (34.5 bar) or above. This classification indicates directly the suitable method of hydraulic computation for the design of the system.
NFPA 750 states that for systems without additives and with working pressures not greater than 175 psi, either the standard hydraulic calculation method or an alternate velocity pressure (Hazen-Williams based) method can be applied, while only the standard method is permitted for intermediate- and high-pressure systems. The pressure classification is not only a design label, it determines whether an engineering calculation approach is even permissible for that system.
NFPA 750 defines Dv as the volume median diameter of the water mist droplets, which is a metric for how tiny the water is atomised. The control of fire by a water mist system is very dependent on droplet size distribution. Finer droplets have more surface area to absorb heat quickly and they are also more effective in oxygen displacement. That is why droplet characterisation testing is part of the evaluation and listing of these systems.
NFPA 750 particularly specifies that where the design goal is fire extinguishment (not only suppression/control), attention must be given to both the possibility for deep-seated flames as well as the potential for smouldering fires, since these behave differently than an open burning fire. For Class B (flammable liquid) dangers, the standard also includes an evaluation of fuel loading, fuel configuration, flash point, and burning rate and preburn time because all of these impact how the characteristics of the fire develop before suppression begins.
Fire suppression is described by the NFPA 750 as a major reduction in the heat release rate of the fire and the prevention of fire regrowth. This is a much lower bar than total extinguishment, and the distinction is important because a system designed simply to suppress a fire (control the heat and prevent spread) may be designed differently – and may leave residual burning – than a system designed to fully extinguish it, which is why the design objective needs to be defined clearly before a water mist system is specified for a given hazard.
