Case study: Bernardin Manor

Posted by Armstrong Fluid Technology on Dec 15, 2023 9:30:00 AM


Bernardin Manor is an assisted living facility in Chicago. Armstrong approached the building managers with a proposal to upgrade existing constant speed pumps with new Design Envelope Tango pumps. 

The three new, properly sized, Design Envelope Tango pumps are operating much more efficiently than the original pumps. Energy savings from the pump retrofit will be over $4,000 per year.

Armstrong maps each individual pump’s hydraulic, motor and inverter variations at the factory to achieve exceptional accuracy throughout the flow range.
With this calibration, Armstrong Design Envelope pumps also serve as flow meters, providing reliable system flow data (+/- 5%). The testing ensures optimal performance efficiency at start-up, while Armstrong’s Pump Manager helps maintain and extend efficiency throughout the pump’s operating life.
