Energy Efficiency with GreenFlo™

Boost Efficiency While Saving Energy

The GreenFlo™ advanced algorithm solution is raising the bar on efficiency standards.

With GreenFlo™ [built into iQFlo™ 3.0], you can enjoy the benefits of exceeding the ASHRAE/ANSI/IES Standard 90.1 energy standards.

QuantumFlo is proud to offer the world’s most innovative booster system technology. Join us in our mission to go green and save some “green” with GreenFlo™, a proprietary algorithm integral to our revolutionary B.O.S.S. (Booster Operating System Software). Experience the future of pumping technology – Go with the ‘FLO!

GreenFlo™ manages energy consumption by detecting, responding, and adjusting to changes in water flow. This reduces energy at low flow conditions, saving owners approximately 20% more than VFDs alone. Additionally, GreenFlo™ exceeds ASHRAE/ANSI/IES Standard 90.1 Energy Standards, ensuring our booster systems remain in compliance with energy standards and requirements.
