Powerful and affordable hydraulic calculation software for automatic fire sprinkler systems. TSHC has all the features you need to enter your system data, evaluate and analyze results, and produce professional hydraulic calculation reports. TSHC uses the Hazen-Williams formula for friction loss, allows pipe and node names up to 8 characters long, and uses U.S. or metric units. TSHC can calculate tree, grid, loop, or custom systems.

185Graph is a 1.85 graph based fire sprinkler hydraulic calculation software program that is designed to graphically display sprinkler demand vs. water supply. It calculates base of the riser demand with the Grid Calculator, Tree Calculator or Head by Head Worksheet and will plot these demands against any water supply. Water supplies can be adjusted for friction loss, elevation and/or hose streams.
