Following a rigorous certification process, Marioff HI-FOG® high-pressure water mist fire protection system with an electric pump unit has received an extended FM Approval to provide fire protection for combustion turbines and machinery with enclosures up to 2300m3. The approval nearly doubles the amount of space Marioff’s flexible fire protection solution can cover and gives the HI-FOG system added flexibility and makes it suitable for different types of turbine models and their configurations, as the spray heads can be installed both on the ceiling and at the midpoint of the turbine. About FM Approvals FM Approvals is an international front-runner in third-party testing and certification services. Marioff, a foremost developer of water mist fire protection technology, is a part of Carrier Global Corporation (NYSE: CARR), the leading global provider of healthy, safe and sustainable building and cold chain solutions. This new, extended approval is the result of long-term cooperation between gas turbine manufacturers and Marioff to gain internationally recognized FM Approvals for using water mist fire protection to protect turbines. Previous and Extended Approval Marioff’s previous FM Approval for combustion turbines and machinery, dated 2013, is for 1375m3 spaces. The extended FM Approval means a HI-FOG system can now be used to protect a wider range of heavy-duty gas turbines and large machinery spaces in enclosures that are almost a thousand cubic meters larger. The extended FM Approval also provides more flexible system installation criteria The extended FM Approval also provides more flexible system installation criteria, as it allows to change the place of spray heads flexibly around obstacles without adding extra spray heads. Previously, obstructions like piping or walking platforms meant adding more spray heads – and more water. The FM Approval was received after a development project between a gas turbine manufacturer, an insurer, and Marioff. Authority Comment “The most important starting point for the innovation process was to consider the practical requirements and limitations of modern heavy-duty gas turbines. Excellent teamwork and the turbine manufacturer’s insights for practical issues helped us shape the HI-FOG solution to fit the industry’s needs." "We are very pleased that the new HI-FOG solution and FM Approval will enable us to better serve our customers in the power generation industry,” said Antti Hurme, Head of Business Development, Marioff. Installation The FM Approved HI-FOG system may also be installed in existing enclosures with gas turbines, oil tanks, electrical transformers, and machinery, as well as greenfield projects.
Marioff is pleased to announce that it’s HI-FOG high pressure water mist fire protection system has received FM Approval in the local application hazard category, expanding the number of suitable applications for the existing technology. Approval from the international third-party testing and certification services basically entails that Marioff’s HI-FOG high pressure water mist fire protection system is now available for wider use in power, process and manufacturing industries. Marioff, a globally renowned developer of high pressure water mist fire protection technology, is part of UTC Climate, Controls & Security, a division of United Technologies Corporation. HI-FOG high pressure water mist system The HI-FOG high pressure water mist system utilizes the full potential of water to protect critical machinery The HI-FOG high pressure water mist system utilizes the full potential of water to protect critical machinery and carry out the firefighting task at the source, thereby keeping property damage and downtime to a bare minimum. “The FM Approval for local application reinforces Marioff’s commitment to provide robust, innovative, high-technology water mist fire protection solutions for our customers,” said Antti Hurme, Global Account Manager at Marioff. Wide deployment in local application hazard category The local application hazard category covers a broad range of industrial applications such as steam turbine bearings, oil skids, diesel generators, hydraulic power packs and other machinery using flammable liquids in large open spaces. Power generation and industrial process machinery use flammable liquids for fuel, lubrication and hydraulics, which can malfunction, causing leakages and leading to fires. FM Approval FM Approval sets the performance criteria for local application water mist fire protection systems and includes dozens of full-scale fire tests representing real fire scenarios such as flammable liquid pools, spray fires as well as a combination of these.
