Powerful and affordable hydraulic calculation software for automatic fire sprinkler systems. TSHC has all the features you need to enter system data, evaluate and analyze results, and produce professional hydraulic calculation reports.

Calculations use the Hazen-Williams friction loss formula, as required by NFPA 13. Wet, dry, preaction, tree, loop, gridded, and custom systems may all be calculated. Multiple water sources, multiple fire pumps, multiple fixed loss devices, negative elevations, metric and U.S. units, automatic peaking, and velocity pressures are all supported.

TSHC's modern syntax highlighting editor allows you to enter sprinkler system data efficiently with input flexibility many other programs lack. Many errors are highlighted in real time. There are "Pop-up helpers" for material and fitting codes so you don't have to memorize them. Automatic "proposals" anticipate the next parameter and type it for you. U.S. users may enter lengths and elevations using foot and inch symbols. Group editing makes it easy to change all values of a specific type in your selection, such as k-factors or discharges. TSHC even allows pipe and node names up to 8 alphanumeric characters long.

TSHC's calculation results window allows you to quickly evaluate your design. All relevant system, pipe, and node data is shown. Also, data may be sorted by clicking on the column heading. For example, clicking the heading 'Pf' in the pipe section sorts all pipe from lowest total friction loss to highest. Best of all, the calculation results window can stay open and visible while you make changes in the editor window! Simply drag the results window to a convenient spot on your screen!

When your design is done, TSHC will print a professional hydraulic calculation report with a comprehensive summary page, full pipe and node information, and source, device, and hydraulic graphs. Letter sized portrait and A4 or letter sized landscape paper sizes are supported.
