Free Software for Sprinkler Hydraulic Calculations by Alan Ashfield

16 completely FREE 'Windows' Fire Sprinkler Hydraulic Calculation Programs for 2016

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.

FREE program #8 of 16 : FREESHP

Main FREESHP screen

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 16 : EASYSHP

Typical results from 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

Qcap / Qmax graph

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.

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.

Summary of all above

Yes, all of my cost-effective "Windows" programs will not cost you anything :-

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!
