[post_content] => Automation has come to the tank storage sector with a vengeance in the last couple of years, changing established working practices and procedures and helping to improve safety and efficiency. That process has lately arrived in the firefighting department, promising better performance and environmental protection.
Two parts of SK FireSafety Group were on hand at last month’s Tank Storage Connect event in Rotterdam, where they each had new developments to show to visitors.
Saval was showing its new SmartMix® electronic foam mixing system, designed to bring added accuracy in the mixing ratio of foam concentrate to water. This is achieved by continuous monitoring of both flows using electromagnetic flowmeters and real-time adjustment of the concentrate control valve. The system employs a state-of-the-art logic specifically developed for SmartMix
In addition to providing an accurately mixed firefighting medium, SmartMix can also reduce the environmental impact of firefighting operations. Its test procedures operate without the need to actually mix water and concentrate, avoiding the unnecessary use of concentrate stocks and eliminating the potential for concentrate to escape the system. During the test the injection point to the firewater system is isolated and the concentrate is diverted through the test outlet fitted with a pressure sustaining valve. Those test procedures also ensure that accurate proportioning is achieved every time.
The SmartMix system is housed in a powder-coated stainless steel cabinet that can be installed in the harshest environments. The cabinet also includes an integrated touchscreen user interface, allowing the user to view system parameters, diagnostics and all process values, alarms and events. All data can be downloaded for analysis.
Saval’s partner company Knowsley SK had its new Turbinator foam mixing unit on display in Rotterdam. Developed from the company’s successful 2P and 3P foam-making systems, the Turbinator is designed specifically for the task using positive displacement technology.
The really clever thing about the Turbinator is that it is powered by water pressure – the water-powered motor and foam concentrate pump are close-coupled and integrated within a single body, so that while every revolution of the water motor delivers a fixed volume of water, the corresponding revolution of the foam pump delivers a fixed volume of concentrate. This means that the foam mixing ratio is maintained, regardless of the operating pressure.
That design also makes the device inherently self-priming and it also generates no wastewater. It is produced in three sizes, ranging from a nominal 4” to a nominal 8”. Knowsley SK also manufactures a unit specifically for offshore applications, in which the 431 stainless steel rotors are replaced by super duplex F55 grade steel, and the mechanical seals are Hastelloy and rubber rather than stainless steel and rubber. This allows it to use seawater as an alternative to fresh water. All products meet the requirements of the EU ATEX Directive.
Speaking to HCB at the Tank Storage Connect event, Peter Robinson, Knowsley SK’s UK sales manager, reported that the company has seen a lot of interest in the Turbinator, not least since its design and independence from a power source makes it ideal for use in a range of applications, such as foam monitors, deluge systems, foam makers and handline nozzles.

Firefighting: Foam on tap
Recent advances in foam making from the SK Group mean less risk of environmental damage and a more reliable response to tank farm fires
