Businesses in the UAE are increasingly aware of safety concerns across the tall buildings which are set to dominate Dubai and other major cities. Very public, dangerous, high-rise building fires have driven demand for better fire safety technology, such as fire pumps, and as businesses look to future-proof fire protection systems selecting the right model could make a significant difference to safety and efficiency.
With advances in accurate data and real-time monitoring being utilised in fire pumps, fire safety technology is continuously advancing to help detect issues and manage performance.
Variable speed fire pumps in particular, have spiked in popularity, and as a result, are improving fire safety across the built environment. Advancing technology has meant that potential risks, such as maintenance issues, can be identified much earlier, helping to predict and prevent potential fires as a result.
Self regulating variable speed fire pumps are considered some of the most sophisticated technology available, as they can respond to the changing demand and adjust motor speed to maintain the target system pressure and provide a stable, controlled performance. This avoids under-pressurisation, ensuring maximum operational efficiency. For example, if pressure drops too low, sprinklers may not discharge properly, and upper floors may not receive enough water. Over-pressurisation is also avoided, which can cause burst pipes, equipment damage or system failure.
The variable speed control unit can also automatically adjust speed, and respond to real-time demand, rather than consistently running at full capacity. This optimises operations more than traditional pumps on the market, often delivering between 30%-50% energy efficiency improvements compared with a fixed speed system.
Self regulating variable speed fire pumps’ ability to respond to the pressure change and adjust speed to maintain a constant discharge pressure, regardless of the water supply, is particularly useful in regions across the UAE, where developers are often expanding water networks. This is typically achieved by adding a secondary water supply, often a water tank, separate to the municipal supply, to ensure the pressure is enough to reach the upper levels of high-rise buildings. The difference in pressure between the two supplies can be substantial, meaning the fire pump must be able to accommodate both pressures, without over- or under-pressurisation occurring.
Modern fire pump systems also offer a lower installation cost, as they are safe, more reliable and reduce reliance on Pressure Reducing Valves (PRVs). This lowers the overall cost and reduces maintenance spending, due to fewer PRVs being installed. According to the UAE Fire and Life Safety Code of Practice, PRVs need to be inspected quarterly and undergo a full flow test annually. With each PRV needing individual tests and inspections, the fewer incorporated in the system the more economical it becomes long-term.
Higher-end variable speed fire pumps models also incorporate diagnostics. A combination of software and sensors can detect and warn when there is a mechanical fault or an issue within the system. Notifications about issues, both existing and predicted, can appear on an easy-to-use dashboard interface, alongside reminders of any scheduled maintenance. This ensures that system operators are kept fully updated about performance and can proactively address any issues before they escalate and potentially put people at risk. These notifications also have the added benefit of alerting system operators before components reach the end of their life, giving enough time for parts that are needed to be ordered without incurring an additional rush charge.
Diagnostic programmes now also have the ability to monitor for trends, provide analysis and create automated reports. This capability goes well beyond preventing equipment failure and can help to enhance the system’s operational efficiency.
Some systems also support remote access, allowing operators to view the data through a dedicated interface. This further reduces maintenance costs, as potential issues are flagged before they escalate and, as a result, technicians are often making small, low-cost improvements rather than large, expensive repairs. Additionally, access to the data means technicians can review what type of work is needed before coming to site. This allows teams to assess the scope of repair work in advance, ensuring the appropriate level of technician is deployed, rather than dispatching a highly skilled engineer unnecessarily. This data-driven approach helps improve efficiency and reduce overall costs.
Data, trends and diagnostics aren’t a standard part of every fire pump system yet, but they should be. Technological advances are making fire pumps more reliable and cost-effective, as well as, most importantly, making them more effective at preventing fires. Intelligent, self regulating variable speed pumps have the unique ability to predict and report issues in the fire system, which, if left unchecked, could have devastating consequences. The ability to not just prevent fires, but predict them, is critical to protecting lives.
