Reduce Energy Waste with Pumping Systems That Adapt in Real Time

As water demand patterns continue to shift in both new and existing buildings, the need for adaptable and energy-efficient pressure boosting has never been greater. Armstrong’s 6800G and 6900 Booster Packages are built around Design Envelope technology, which matches pump output to real system demand. Because most buildings operate at part load for much of the day, running pumps at higher speeds than needed wastes energy and shortens equipment life. Design Envelope control helps ensure pumps operate only at the speed required at any moment using water system demand matching, reducing operating costs and wear on critical components.

Why Demand Profiles Matter

Over time, fixture changes, building redesigns, added backflow protection and pipe scaling can all shift a building’s water demand profile. The Design Envelope sizing approach anticipates these changes so the booster continues to perform effectively without costly system rework.

Higher Efficiency Through Permanent Magnet Technology

The 6800 series incorporates Design Envelope Permanent Magnet motors that offer clear efficiency advantages compared to traditional variable speed induction motors. These motors maintain higher efficiency across the entire operating range and deliver especially strong performance at lower speeds. Additional benefits include reduced maintenance needs, quieter operation, smaller size and a wider range of available speeds for improved design flexibility.

Integrated Controls and Intelligent Operation

Each booster package is assembled and tested to design conditions in an ISO certified facility and includes embedded logic that manages pump staging, setpoints and no-flow conditions. Features such as softfill, pressure setback, alternate setpoints and tank optimization help maintain stable operation under all demand conditions. Real-time data, flow analysis and energy profiling support more informed monitoring and decision making.

A Compact, Flexible Package

The 6800 and 6900 models offer some of the smallest footprints in their class, with space savings of up to 25% and 45% compared to competing models. Interchangeable inlet orientations and optional loose headers simplify installation in tight mechanical rooms. Integration with common BMS communication protocols supports easy connectivity, and commissioning is guided through a simple step-by-step software wizard.

Built for Compliance and Water Quality

The booster packages meet ASHRAE 90.1 requirements and are fully certified to NSF 61 as complete systems, ensuring delivered water meets strict health standards for both new and retrofit applications.
