Thank you for visting my website describing the most extensive portfolio of fire sprinkler hydraulic calculation computer programs anywhere on the Internet :-
- All are entirely FREE - no charges for anything at any time, now or in future and very cost effective as they don't cost anything
- I am just a private individual who has been researching different user-interfaces and mathematical details over the last 7 years or reacting to suggestions from users, so they are all free with my compliments as no reason to ever charge you for my efforts
- No 'premium' or 'paid-for' versions are available - just the 16 listed below
- All are fully up-to-date and comply with the latest, most common sprinkler rules - NFPA, FM Global and derivatives of EN12845
- Only Metric (S.I.) units applicable worldwide but not in USA / Myanmar
- Printout formats and screen displays acceptable to the respective Fire Authorities, Reviewing Bodies, Insurance Company inspectors in your country, subject, of course, to individual job checking
- None, however, have ever been "approved" by any of these organisations as they would never do so for any program that they did not directly control and only commercial firms and dedicated individuals will ever produce such specialised software
- Some suppliers say that their programs follow the NFPA 13 / 15 / 750 Rules but the printout format is nothing like that given in the NFPA documents so unlikely to be acceptable
- All calculations are performed in accordance with established sprinkler rules and so give EXACTLY the same answers as the few ~20 year old programs many of you might still use or have purchased
- There are NO other free fire sprinkler hydraulic calculation programs elsewhere on the Internet, so no point in searching for alternatives as you have found them all here
- Other sites may say their programs are free, but that is ONLY for download and 15 / 30 day trials - you have to PAY to actually use them on your projects
- WINDOWS XP, Vista, 7, 8.1 or 10 with Arial and Lucida Console fonts (only FREESPRAY is available for Linux, Apple MacOS X or Google Android but not Chromebooks)
- Simple DOWNLOAD (0.5 to 2Mb EXE file) - no install/set-up, addons, viruses or malware so you can have multiple copies direct from this HTTPS website
- Guaranteed NO usage tracking, spyware, toolbars, search engine links, unwanted extra or potentially unwanted programs
- No charges for annual updates, extra copies, training or support by Email
- No personal details ever needed or Email addresses, registration, activation, upselling, tracking, expiry dates, time outs, degrading over time, unlock codes, credit / debit / payment information, advertising or 'in-app' purchases
- You will see that I have always give the extent and scope of the input data needed for the various programs - strangely missing from most other suppliers websites and so you only find out what information is actually needed to perform the full hydraulic calculations for the one or more design areas of your projects until you download them and read the help screens
- All my hydraulics programs are really comprehensive in their features and options but are easy to use with modern intuitive, graphical interfaces, inbuilt help and demonstration examples proved on real projects
- I think that you will find that nobody has produced any NEW software in this field (apart from my programs listed below) as they obviously cannot compete with all my FREE ones so if you are waiting for your current supplier to come up with a replacement, you are going to be disappointed
- I, on the other hand, are quite able and willing to DEVELOP any similar sprinkler hydraulic calculations program that you, as an individual or company, may require for your own use (not to sell of course!) - just Email me a full specification (click here for more details)
- I also do not offer any paid for or free on-line video or all day training courses anywhere that overwhelm you with the sheer volume of content - much better to have one of my FREE programs on your PC that you can learn step-by-step at your own pace and I am here by Email should you get "stuck" at any point or if anything is not clear, all at zero cost
- You get FREE technical support by EMAIL from the same person who wrote these programs but I will never send you an Email, except to reply to your one(s) as I do not have any 'partners' or incentive to sell you anything
- I am not on Facebook, Twitter, LinkedIn, Skype or contactable by telephone
- On the other hand, if you think that "anything free is not worth what you paid for it" then just ignore my programs and buy one from another supplier and see how little different they are
- Try one of my completely free programs and see how you get on or compare it with your current expensive hydraulics software package and I will promptly respond to your comments / criticisms
- If you have NEVER done any hydraulic calculations before, then I suggest EASYSHP or AACALC9 as detailed below to start with
6th December 2016 - Recent users of FREESPRAY have translated the 18 project questions and 11 warning messages into German, Icelandic, Norwegian and Polish.
6th November 2016 - FREESPRAY has already been translated into Danish, Dutch, French, Italian, Portuguese, Spanish and Swedish.
6th October 2016 - You can download the full source code and a test file for FREESPRAY to do the full hydraulic calculation of spray, deluge, drencher, hydrant etc. systems using the Hazen-Williams formula for the LINUX, OS X and ANDROID operating systems. If you get a BROWSER WINDOW on screen after the download, then simply Copy/Paste the whole text into NotePad or another Text Editor and save them as freespray.pp and test1.txt in a new separate folder/directory. All the instructions are given as comments in the source code listing and no further programming knowledge is needed unless you wish to translate it into your own language or add pipe types/sizes/fittings.
6th September 2016 - Some out-of-date programs deleted
6th June 2016 - AACALC11 updated (#5 of 16 below)
Please SCROLL DOWN for summaries, download links, more detailed information and instructions for each of my 16 FREE FIRE SPRINKLER DESIGN programs ...
FREE program #1 of 16 : FREEHC

FREE program #4 of 16 : 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 16 : 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 16 : 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 16 : 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 16 : 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.
Click here for further screen shots / details about FREESHP including new pipe types added 08.10.15 or click here to download FREESHP [09.12.15 954 kB] directly.
FREE program #9 of 16 : 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 / Inspectors still insist on seeing your sprinkler layout drawings so have to manually match them with the hydraulic calculations.
FREE program #10 of 16 : 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 16 : 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 16 : 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 16 : 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 16 : 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 16 above for Qcap / Qmax graph.
FREE program #16 of 16 : 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.
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.

- Please check you are looking at the HTTPS encrypted version of my website and all the software is in the English language and metric units only. Kindly note that I am based near Peterborough in the UK so potential users in America would be ill-advised to contact me by Email lest they then get tracked by their government for communicating with somebody outside the U.S.A.
- With all the current privacy and security threats / concerns surrounding tracking of Internet users, you should only visit websites starting with HTTPS and avoid unencrypted HTTP ones whenever possible
- For the EN12845 RULES used throughout Europe, I offer AACALC7, EASYSHP, VSHP, HYD, IPDS43 and AAVIEW7 with NEW3RD just for BS9251:2014
- For the NFPA 13/15 + FM GLOBAL RULES used worldwide, I offer FREESHP and AACALC9 for all types of hydraulically calculated sprinkler systems but (for the 99th time!), there will NEVER be any 'imperial' versions. AACALC12 is a CAD program for Pipe Schedule systems with FREEWATERMIST for all types of water mist systems to NFPA 750.
- For ALL SPRINKLER RULES, I offer AACALC8, AACALC10, AACALC11 and my latest FREEHC program for multiple sprinkler rules and languages.
