Hydraulic Calculation Software

for fire sprinkler & water mist systems

Fire protection engineers use FHC Hydraulic Calculation Software worldwide to help design the most demanding fire protection systems to international standards, including EN 12845, BS 9251, EN 16925, EN 14972-1, FM Global, NFPA 13, NFPA 750 and LPCB / BRE regulations.
FHC hydraulic calculation software for fire & water mist systems

FHC for all types of water base
fire protection systems

FHC is a tried and tested hydraulic calculation & analysis software for fire sprinkler systems. It has helped hundreds of companies with their design projects, from complex roof & rack systems for some of the most extensive logistics facilities to car manufacturing plants. Whatever the project size and complexity, FHC will be able to help.

FHC is fast, accurate, dependable, easy to learn, and can calculate any pipe network from a tree and loops to complex grids.

FHC can calculate any type of hydraulic model

Fire sprinkler system hydraulic calculation

FHC can calculate any type of hydraulic model

from the most complex fire sprinkler installations with roof and racks, water mist systems, water spray systems, hydrants or a water cannon installation. In addition, FHC can calculate almost any water-based fire protection system and is very flexible. Any pipework network can be built from a simple tree, looped to multiple looped systems or any combination.

As you create the pipe network in FHC and when you connect the pipes, FHC will automatically find any tee's and elbows and look up the equivalent length in its extensive tube and fitting database. This will save you considerable time and is less prone to input errors. Also, if you change the pipework configuration, FHC will automatically make the necessary fitting adjustments to ensure your hydraulic model is up to date.

FHC fast calculation algorithm

FHC will give you the results you require in seconds, allowing you to concentrate on optimising the system for the most economical design. In addition, you can choose to use Hazen-Williams or Darcy-Weisbach pressure loss equations to calculate the pipe friction loss. FHC is suitable for fire sprinkler systems & high and low-pressure water mist systems, and other high demanding systems.

FHC can calculate the source pressure and flow required for the system, or you can specify a fire pump curve, constant pressure pump or a city water supply, and FHC will balance the system to the water supply.

FHC in action

FHC Hydraulic Calculation Software you can build complex hydraulic models quickly with a set of drawing tools which allow you to draw the hydraulic model of the system on your computer. As a result, you can instantly see the pipe network updating, which minimises input errors and allows you to concentrate on optimising your fire protection system, saving design time and installation costs with smaller pipe sizes or a small water supply.

Water mist systems

The FHC software has a long association with water mist systems. Leading water mist manufacturers use it for calculating high-pressure systems for marine and industrial applications to low-pressure systems for hotels and residential accommodation.

FHC can be used for low, intermediate and high-pressure systems as defined in NFPA 750, and you can easily switch between the Hazen-Williams and the Darcy-Weisbach pressure loss formula.

We support all major water mist design standards, including NFPA 750, BS 8458, BS 8489, EN 14972-1 & Vds 3188

Residential Sprinkler Systems

Canute has been at the forefront of the domestic and residential fire sprinkler development over the last two decades and has helped to shape both British & European design standards. As a result, FHC can be used for BS 9251, EN 16925, NFPA 13D & 13R and many other international design standards.

We strongly believe that residential sprinklers will help save life, property and the environment. With our expert knowledge of this technology, it’s not surprising that FHC can undertake the required hydraulic calculation, and you can also have our expertise to help you through.
