The Hydraulic Calculation Module of Marioff’s New HI-FOG® System Designer Tool Receives FM Approval
15 September 2017

VANTAA, Finland, Sept. 18, 2017 — Marioff is pleased to announce the hydraulic calculation module within the water mist design, evaluation and optimization module of HI-FOG designer has received FM Approval certification. By obtaining FM Approval, the calculation module of HI-FOG designer has been tested and verified to meet rigorous standards of quality, technical integrity and performance. FM Approvals is an international leader in third-party testing and certification services. Marioff, a leading developer of water mist fire protection technology, is a part of UTC Climate, Controls & Security, a unit of United Technologies Corp. (NYSE: UTX).

“Our unique HI-FOG design tool enables users to perform accurate hydraulic calculations to assess and optimize the design and performance of the HI-FOG system.” said Joachim Gabrán, marketing director, Marioff. “The FM Approval of the hydraulic calculation module reinforces Marioff’s commitment to provide innovative, high-technology water mist fire protection solutions for our customers.”

 HI-FOG designer provides hydraulic calculation and performance optimization in the design of the HI-FOG system. Based on its calculation features, the tool makes pressure drop calculations for each nozzle, ensuring the specified operating pressure is met. The accuracy of this functionality has been verified in extensive field validation tests, which confirm HI-FOG designer delivers accuracy equal to or better than the traditional Darcy-Weisbach methodology in predicting pressure drop at the given nozzle. The HI-FOG designer takes into account the diverse HI-FOG system layout configurations, nozzle types, and system pipe length and diameter.

With the new HI-FOG designer, users get pressure loss data directly from the engineering design software. The software also promotes faster system design, pipe size optimization, bill-of-material accuracy and allows for viewing the system design in the building information modeling (BIM) software.
