Our Story
The company behind the world's most trusted hydraulic calculation software.
Half a Century of Innovation
In 1976, Hal Sanders set out to solve a problem that every fire protection engineer faced: hydraulic calculations were tedious, error-prone, and time-consuming. What started as a mission to bring accuracy and automation to this critical discipline has grown into a 50-year legacy of industry leadership.
For five decades, HRS Systems has partnered with thousands of fire protection professionals to refine, improve, and advance the tools they depend on. Now, with the launch of HASS Cloud, we're writing the next chapter. A chapter defined by modern technology, seamless collaboration, and the same unwavering commitment to accuracy that has been our foundation since day one.
And we can't wait to show you what's next.
