AFEX fire suppression systems are designed and purpose-built to protect heavy off-road equipment from the threat of fire. At the heart of these critical safety attachments is the AFEX Control Unit, which combines the latest in micro-processor technology with the company’s signature durability, resulting in the ultimate fire suppression system control and performance.

To ensure your machine is protected in the event of a fire, audible and visual signals alert the operator to any problem or alarm conditions. These alerts are stored on the Control Unit’s internal log for subsequent troubleshooting and are shown on the LCD display in the local language, meaning they can easily be reviewed directly on the machine itself.

A pioneering component of telematics integration within the industry, the AFEX Control Unit enables asset managers to track a fire suppression system’s status alongside other key operating metrics quickly and conveniently. Using dedicated outputs from the AFEX Control Unit and inputs on the telematics system, end users can monitor for problem, alarm, and discharge status. Beyond that, for autonomous vehicle applications, the AFEX system can be configured to discharge when signaled by the vehicle remote control.

Introduced at MINExpo 2012, the AFEX Control Unit now has over two years of field-proven application in the mining, waste, and forestry industries. It is FM approved, CE marked, and certified for use in Russia and Australia. Compact enough for console mounting, the box itself is tightly sealed to protect the internal components, and its battery provides a year of stand-alone power. It utilizes a customizable harness with standardized connectors for efficient/affordable installations and water-tight connections.

The AFEX Control Unit supports two distinct detection circuits, which allows users to monitor two separate parts of the machine independently. Able to support two separate electric actuators, systems may be designed to have secondary discharges when desired. Another benefit is that there is no limit to the number of tanks the Control Unit can support. Programming of the desired options is a simple matter with the integrated screen, and push-button actuation is available.

The AFEX fire suppression system itself is designed for redundant system activation, so in the event of an electrical system failure, the system can still be actuated manually. The agents used in the system are either an A:B:C dry chemical, an environmentally-friendly liquid agent (rated for use down to -40 degrees C/F) or a combination of the two agent types. As hot-running Tier 4 engines become more common in the field, these dual agent systems will often be the right approach as they take advantage of both the fast knockdown of the dry chemical and the cooling effect and suppressive properties of the liquid agent.
