Heysen Tunnel – Double Electric Mist Sprinkler Fire Pump System for Critical Infrastructure

Project Overview

BKB Group Australia proudly delivered a double electric mist sprinkler fire pump system for the iconic Heysen Tunnel on the Southeastern Freeway in South Australia. This vital infrastructure upgrade ensures enhanced fire protection within one of the state’s most critical transport corridors.

The project involved the design, manufacture, and supply of high-performance electric mist fire pumps, engineered to meet the demanding safety and operational requirements of tunnel environments. Mist sprinkler systems are specifically designed to control and suppress fires with minimal water usage, reducing damage and maintaining visibility — a key factor in tunnel fire response.

Installed in accordance with AS2941:2013 and relevant national fire safety standards, the system delivers rapid activation, precision control, and long-term reliability under high-risk conditions. The dual electric configuration ensures redundancy, providing uninterrupted protection even in the event of power loss or system failure.

This project demonstrates BKB Group’s expertise in providing advanced fire protection systems for tunnels and high-risk infrastructure, where safety, system efficiency, and regulatory compliance are non-negotiable. From design to delivery, BKB’s comprehensive approach ensures seamless integration into existing systems and maximum operational uptime.
