Nozzle - Sprinklers

HI-FOG® sprinklers are the key component that makes the HI-FOG® water mist fire protection system particularly suitable for fire protection. HI-FOG sprinklers make the most of water mist with minimal water usage. The reliability of the sprinklers has been verified through numerous type approvals, for example, FM, VdS, UL, DNVGL, Lloyd’s and ABS.

The compact design of HI-FOG sprinklers minimizes the amount of space needed and makes it easy to preserve the aesthetic integrity of the installation site. This is especially important for culturally and historically significant locations.

Features and benefits:

• Each sprinkler consists of a sprinkler body, a spool valve, a heat sensitive glass bulb and a strainer to prevent clogging.
• The heat-sensitive glass bulb inside the HI-FOG sprinkler explodes in the case of fire.
• When the bulb breaks, a spool drops inside the sprinkler. This allows water to discharge through the sprinkler orifices as fine water mist due to high water pressure.
• There are different heat-sensitive bulbs to suit different temperatures. Marioff offers five standard options ranging from 57°C to 141°C.
• Marioff has a wide variety of coating finishes available.
