FREE program #1 of 20 : FREEHC
FREEHC is a new, comprehensive and completely free "Windows" program for the full hydraulic calculations of all types of fire sprinkler protection systems to most countries rules and languages as follows :-
- Light, Ordinary or High hazards for any building occupancies
- Wet, dry, pre-action, end- or centre-fed, looped, gridded or birdcage pipework layouts or any combination
- Roof, roof+rack, above / below ceiling, ESFR, spray, drencher, deluge, water curtain systems, hydrant ring-mains or, in fact, any water based fire protection system
- Any area / density of coverage requirements easily complied with
- Multiple sprinkler rules applicable to any country - EN12845, NFPA and FMGLOBAL initially provided, others easily added except BS9251/BS8458/BS8459/EN16925
- Multiple languages (but not UniCode-based ones at present) - English initially, others requiring just translating a simple text file with instructions provided
- Metric units only of course - I presume any countries still using "imperial" already have such software for their specific use
- User editable database of pipe types, sizes and fittings to suit any project
- Simple "point and click" pictorial, fully interactive, 3D user interface showing plans, elevations or isometric views of your pipework layout

FREE program #4 of 20 : AACALC12
AACALC12 is for the Pipe Schedule sizing method in NFPA 13 directly from your CAD drawing to produce a materials take-off quantities list / estimate in metric units only.
FREE program #5 of 20 : AACALC11
AACALC11 is a very simple spreadsheet based program to enable end-fed, looped and gridded fire protection pipework systems to be quickly entered, analysed and evaluated so that you may learn about full hydraulic calculations of sprinkler systems for yourself. It also shows a drawing (along with the input data and the results) by allowing the node numbers to represent the X and Y position percentages on the screen.
Click here for further screen shots / details about AACALC11 or click here to download AACALC11 [06.06.16 555 kB] directly for Hazen Williams "C" factors from 20 to 200 specifically for really old underground pipes to FM Rules.
FREE program #6 of 20 : AACALC10
AACALC10 is a spreadsheet based program to enable end-fed, looped and gridded fire protection pipework systems to be quickly entered, analysed and evaluated so that you may learn about full hydraulic calculations of sprinkler systems for yourself.
FREE program #7 of 20 : AACALC9
AACALC9 is simple "point and click" drawing program for first-time users to the NFPA 13 / 15 Rules and dating from February 2014.
FREE program #8 of 20 : FREESHP
Calculation of hydraulically designed sprinkler (room design and area/density methods) and spray systems to the NFPA 13/15 and FM Global Rules in metric units. Node references are only required at tees / crosses (not at each end of all pipes) and you give the size, length, direction and slope of the pipes to the operating heads / nozzles so a 3D picture is produced as a DXF file. There is just one way and place to add, break, copy, delete, edit, move, locate or view pipes - no confusing options to learn or superfluous videos / manuals needed to find out what does what! You may have a background CAD drawing so can "draw" the pipes on the building / rooms / services plan rather than a blank screen.
Click here for tutorial [24th January 2013 - about 9kb - just "Save" it to somewhere on your hard disk]. I have redone this as as .RTF file so users with HD screens can just reduce the width of FREESHP and have WORDPAD or similar running alongside, making it easier to step through the various options and see the program in operation.

FREE program #9 of 20 : EASYSHP
Full hydraulic calculation of sprinkler and spray systems to the European EN12845 Rules in metric units. Innovative / unique features include just 4 screens - "File options", "Project and Pipe Data", "Calculate and Show Results" and "Help" - very quick and easy to apply for your projects using simple data entry procedures and immediate calculations. Does not need to produce a drawing as most Reviewers still insist on seeing your sprinkler layout drawings so have to manually match them with the hydraulic calculations.
FREE program #10 of 20 : IPDS43
A standalone program for the calculation of the Qcap and Qmax values for the Installers Pump Data Sheet as the EN12845 and similar Sprinkler Rules in the same format as EASYSHP, so can also be used with HYD and older programs that do not include such an option. You just enter the flows, pressures and highest heads for the most remote / favourable design areas as well as the pump / tank details. These are typed in on simple "tabbed" data entry screens and you can view the resulting diagram on the same screen. If you hold your mouse button over one of the 8 data points, you can then slide it up or down and have the pump curve drawn out to suit with the revised Qcap / Qmax values.
FREE program #11 of 20 : VSHP
Full hydraulic calculation of sprinkler and spray systems to various International Rules in metric units. Innovative / unique features include an "all-in-one" user interface without needing to draw out the pipework scheme, a "grid wizard" option to automatically calculate the most remote / favourable design areas and show the Qcap/Qmax graph and easy to follow results presentation.
FREE program #12 of 20 : AACALC7
Full hydraulic calculation of sprinkler and spray systems to the European EN12845 / CEA Rules in metric units. Innovative / unique features include a very comprehensive options list, producing a zoomable 3D "picture" of the pipework / heads with an aerial view on a building "background", multiple water supplies, unique range numbers (so a complete range can be copied with a single number) or pipe-by-pipe, range-by-range (using "node" numbers that you may be used to), fast calculations and easy to follow results presentation. LibreCAD (http://librecad.org) is Free Open Source Software for the creation / amendment of the DXF drawing files produced by AACALC7.
FREE program #13 of 20 : AAVIEW7
A free viewing program for the various file types from my AACALC7 program including the CSV and XML options and 2D DXF CAD files as shown above.
NEW3RD is a very simple "page" based program just for BS9251:2014 Residential and Domestic fire sprinkler occupancies of 1 to 4 heads in 1 or 2 design areas based on the category and mains supply or stored water systems in metric units only.
FREE program #15 of 20 : 3RD
Full hydraulic calculation of residential / domestic sprinkler systems to BS9251 Rules (not NFPA 13D or 13R) in metric units. Innovative / unique features include a simple data entry method with different water supply options and rotatable 3D view with comprehensive results presentation all set up for the cheap "netbooks" with 1024x600 screens.
This has been replaced by NEW3RD and is left here for legacy systems only.
FREE program #16 of 20 : HYD
Full hydraulic calculation of sprinkler systems to BSEN12845 Rules in metric units. Innovative / unique features include a simple nodes + pipes data entry method on one screen, editable pipe types/fittings database provided now free for all it's previous users. See also the IPDS43 program #10 of 20 above for Qcap / Qmax graph.
FREE program #17 of 20 : HPCO2
High pressure Carbon Dioxide pipework / nozzles calculations program to the NFPA 12, BS5306 and ISO6183 standards in metric units. Innovative / unique features include a simple "spreadsheet" like data entry method on one screen, rotatable 3D "picture" and user editable pipe types/fittings database provided free for all it's previous users. A new option 'EXACT' in Q9 will determine the required nozzle sizes in mm to maintain the specified discharge time in minutes, rather than selecting the nearest size from the database.
Click here for further screen shots / details about HPCO2 or click here to download HPCO2 [930 kB] directly. However, I do NOT have any software for low pressure CO2, FM200, Inergen, Novec1230, Argonite, LPG Inert IG-55, Nitrogen IG-100, Argon IG-01, Proinert or any other fixed-fire fighting gaseous systems, as only their suppliers have the equations, tables, procedures etc.
FREE program #18 of 20 : AABACKUP
A useful "one-click" utility to copy all your data files from my various free programs to another folder on your computer, another PC on your network or NAS, USB drive or external hard disk and perhaps for further archiving to the "cloud" or CD / DVD for off-site retention. Very simple and quick to use but I could do a YouTube video if needed!
FREE program #19 of 20 : SHP4FPC
I have provided full details of a new full hydraulics calculations program using the FREE PASCAL COMPILER at www.freepascal.org - see the SHP4FPC page. This is the ONLY place on the Internet offering the complete source code listing entirely for FREE to enable you to produce your OWN hydraulics program if you already know (or wish to learn) the Pascal computer language, or if you prefer Basic ...
FREE program #20 of 20 : SHP4MVB
I have retyped in the PASCAL version of SHP4FPC in BASIC for Microsoft Visual Basic 2010 Express and called it SHP4MVB - details are on the SHP4FPC page. This is a 900 line listing and the form layout files of a complete WINDOWS program, operating just like those you are already used to for you to modify / extend as required.
Don't see what you want?
Then just Email me your requirements / specification / suggestions and I will consider producing a new, free program (in C++ or Pascal for Windows or Linux as you can also receive the source code if you are thinking of producing your own in-house software) for any sprinkler related calculations task.

If you are a sprinkler designer, installer, contractor or consultant, please could you contact the appropriate body in your country with this link if you think it would be of interest.
Thank you for taking the time to read the HOME page of my website - didn't take long, did it?
Why not try out one of my programs; I suggest you start with AACALC8 and see how you get on. If you don't like it, just delete it as it did not cost you anything and choose another of my programs or another supplier, if you can find one!
