An example two-installation control valves supplied by one water supply. The first installation is a grid roof sprinkler system designed to give 12.5 mm/min over 260m2, and the seconded installation feeds the in-rack sprinkler system. The FHC program calculated this system in under 1 second.

Roof and rack sprinkler systems designed to EN 12845

Within FHC we have specified the required density at roof level and the minimum operating pressure of 2.0 bar for the sprinkler heads within the racks. The FHC program will automatically balance the water requirements for the two installations and will allow you to optimised the pipe sizes by making global or selected changes to the pipe sizes. This can help the designer reduce pipe sizes and minimise the water flow requirements.
