FHC
Hydraulic Calculation Software
for fire sprinkler & water mist systems

FHC for all types of water base
fire protection systems
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

FHC can calculate any type of hydraulic model
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 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
Designed for international use,
trusted by thousands
Water mist systems
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
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.

Technical Specification
FHC is a full hydraulic calculation program for use with fire sprinkler systems and other water based fixed fire protection systems to International standards. It has been used successfully with fire sprinkler systems, water spray, ESFR, deluge, drencher, hose reel, hydrant, foam sprinklers, ring mains, foam monitors and water mist systems.
- Complies with international standards such as NFPA, FM and LPC
- Any type of pipe network can be modelled such as trees, loops, grids or any combination
- Models fire sprinkler systems, deluge, ring mains, hydrant and much more...
- Multiple pipe types
- Specify a global design density or set each head individual
- Automatically find the most remote head or the four MRH in the case of LPC and EN 12845.
- Automatically includes tee and elbows equivalent lengths
- Automatic pipe sizing based on maximum pressure drop or pipe velocity (tree systems only).
- Automatic pipe node numbering.
- Calculate source pressure and flow or balance to a water supply curve such as a fire pump or city supply.
- FHC can use Hazen-Williams or Darcy-Weisbach pressure loss equations
- Isometric, plan and elevation schematic views of the pipe network
- Easy to read and inclusive reports which you can preview and output to PDF.
