After a major refurbishment to guest suites and event spaces, managers at the Park Hyatt hotel wanted to improve heating efficiency and reduce energy use. Armstrong recommended replacing 1 of 2 existing pumps
with a Design Envelope DEPM pump, to provide a head-to-head efficiency comparison.

The new Design Envelope pump reduced energy usage by 60%. 

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.
