AccuMax Fury & Fusion Electric Multi-Point Injection

(Class B Foam)

The new fully automatic AccuMax direct injection proportioning systems bring the most advanced technology and innovation to the industry’s easiest to use Big Water foam system for industrial applications-all with pinpoint accuracy. Two models are available; the Fury for standard proportioning control and the Fusion for those wishing to save even more panel space by incorporating Elkhart Brass electric discharge valve control into one operator interface.

The AccuMax Advantage

Big water flow requires dependable, accurate and easy to use foam proportioning. By incorporating the most advanced microprocessor-driven control and measurement technologies, the AccuMax series of proportioners sets the industry standard by delivering unmatched accuracy with extreme ease of use. At the push of a button, these hydraulically-powered systems measure water flow and automatically inject the desired amount of foam concentrate; all with pinpoint precision.

In addition, greater performance is achieved at the nozzle as flow sensor technology does not restrict flow like eductors and ratio controllers. The true flow-based operation allows unlimited placement of the apparatus, meaning increased safety with positioning further from the incident. All AccuMax systems utilize industry-proven and dependable rotary gear foam pumps. High drafting capabilities allow off-board pickup for foam operations or tank refill, which is crucial for higher flow demands or when changing concentrates.

Calibration and tests can be performed without mixing concentrate with water, saving thousands of dollars in wasted concentrate over the life of the vehicle. It’s also environmentally green as reclamation of foam solution is not required.

A simple push of the line control “ON” button activates the system’s electronics and engages the hydraulically-driven concentrate pump. The Hydraulic Controller manages overall performance as it receives information based on water flow and foam requirements, via CAN bus network, from each discharge and orchestrates foam delivery automatically to each. A compact control module for each outlet allows the operator to choose between plain water or solution. If foam is required, proportioning is automatic, based on programmable default injection percentage. Injection rates are easily changed at the push of a button.

Available in either single or multi-point injection and with capacities to 300 gpm (1,136 LPM), AccuMax delivers extreme foam concentrate for any “Big Flow” application.

Foam Pump

Fire Lion and Trident rotary gear pumps available in all offered capacities. All pump options are capable of drafting for off board pick-up and are constructed with corrosive resistant bronze, stainless and composite. All pumps meet NFPA and are UL listed.

Foam Pump

All the injection logic comes from the hydraulic controller and the hydraulic pump is directly connected to it. The rest of the system is controlled via CAN bus. This single system controller receives real time data from all system components and manages automatic supply to all foam capable outlets.

  • Controls speed of hydraulic pump
  • Tells each line control injector what position to move the foam metering valve based on system demand
  • Receives water flow and foam flow information from each line control injector in the system
  • Calculates foam flow for each line control injector based on operators request
  • Total all water and foam flow broadcast on the network
  • Controls speed of foam pump RPM
  • Overpressure protection, system will reduce pump speed when foam manifold pressure exceeds
    300 psi (20 BAR)
  • No foam shut down; system will shut down when no foam flow is detected for over 40 seconds

Optional Backup/Watchdog

The AccuMax system has an automatic hydraulic backup system in the event something happens to the main control during operation. The system incorporates a second full microprocessor board installed within the hydraulic controller as an automatic backup I/O module. This ensures continuous operation in the unlikelihood of a catastrophic event of the main processor. Upon startup, the system runs through full electronic and component check.

The Power of the Safe Fleet Platform

The AccuMax System communicates via CAN bus (Safe Fleet SafeLink network). This allows a greater level of apparatus integration with other Safe Fleet brand products (FRC, Elkhart Brass). This is physically connected on a custom CAN bus (Safe Fleet SafeLink network) and power harnessing system for greater network fidelity making the installation of each device a single connection. All wires are water tight, over-molded, and sealed.

Line Control Injector

The line control injector in the AccuMax system controls the foam injection rates based on the operator’s chosen injection percentage and the discharge water flow.

  • Required on each foam capable discharge
  • High Flow Range - custom cut-ball foam metering valves deliver the widest range of foam flow for every size injector with pinpoint accuracy
  • System capable of 1-15 individual line controls
  • 4 sizes to accommodate all flow requirements

Fusion System Discharge Valve Options

Unibody valves from Elkhart Brass, offered in both ball and butterfly style, are the only valves in the industry completely engineered and designed with simple, trouble-free configuration, installation, operation, and service in mind.

The Unibody ball valves, built with a 316 stainless steel ball, corrosion resistant brass alloy body, and DuPont Hytrel self-adjusting seats, make the ball valve a strong, dependable choice for your fire apparatus. A standard working pressure of 250 PSI (17 BAR), sizes from 1.5" to 4", along with various endcaps and adapters makes the Unibody compatible with most fire apparatus plumbing designs.

The butterfly style valve, available in 3", 4", 5", 6", and 8" options, is designed utilizing industry standard flanges to meet your specific requirements. Butterfly valves are available in cast iron, carbon steel and 316 stainless steel and offer working pressures from 250-285 PSI (17-20 BAR).

All Unibody valves feature a 10 year limited warranty.
