Further, water mist systems can activate faster than traditional sprinkler thanks The velocity through the nozzles is high and the mixing in the pressure relief valves can be installed which open in the case of a gas outlet and ventilate Halon Options Technical Working Conference, Albuquerque, NM, 2005. 24.

Association of Therefore, expert interpretation and further work is required. High pressure water mist system is a system in which the system pressure is great “FOGTEC systems use pure water, converting it to fine mist at a pressure of 60 to of conventional low pressure systems. This Design work is carried out on. HI-FOG system use high pressure to produce a fire water mist with average drop size of 50 120um. This ultra-small D. R. Gupta Engineering Works.

Today, there are more than 1,300 inlet fogging systems in use around the world. Fog systems are installed on large frame-sized gas turbines, on aeroderivative turbines and on smaller single-shaft industrial turbines. An AIS Greenworks high pressure fog specialist is always on call to service the fog systems we install, and all parts are readily available from our warehouses Australia wide.

30 Jul 2012 The water mist system is comprised of two HI-‐FOG® GPUs (GPU-‐1 and GPU-‐ 2) cylinders are stamped with a 2400 psig working pressure.

The means to release the system manually at the skid shall be provided. J. The HI-FOG ® system shall be fitted with one high pressure nitrogen cylinder. The nitrogen cylinder shall be of the off-the-shelf type and shall be fitted with The HI-FOG® water mist displaces oxygen at the seat of the fire and quickly cools the surrounding air, effectively surpressing and controlling the fire before it can spread or reignite. This is achieved with remarkably little water: HI-FOG® uses up to 90% less water than conventional sprinkler solutions. 2017-10-02 Marioff HI-FOG® is a water mist system that uses very fine water spray to protect your critical assets from fire.

HI-FOG SPUs can be custom built in a range of different sizes and configurations, and each unit can be designed to connect to both main and emergency power supplies. Mist system, which replaces existing systems in the field of humidification and cooling, offers effective solution methods with its special working principle.The revolutionary high-pressure fog systems, in particular to improve the quality of the products and the working environment, also offer special potential in reducing production time. The first commercial inlet fog systems were installed on gas turbines in the late 1980s. Today, there are more than 1,300 inlet fogging systems in use around the world. Fog systems are installed on large frame-sized gas turbines, on aeroderivative turbines and on smaller single-shaft industrial turbines. VANTAA, Finland, March 18, 2015 — Marioff is launching the new generation HI-FOG® 3000 sprinkler series for marine applications.

Therefore, fire suppression with water mist minimizes the intended to describe the state of HI-FOG products and system configurations at the time of its publication and may not reflect the product and/or system configurations at all times in the future.

Water mist is produced through the special design of the nozzles.

HI-FOG® is a high-pressure water mist system that is powered by constant-pressure electric or diesel pumps, or by pressurized gas.

The proprietary MeeFog™ nozzles then atomize the water into billions of ultra-ﬁ ne fog droplets. By taking advantage of the adiabatic process, existing heat in the air evaporates the water droplets.
