Inox, a leader in India’s Cinema exhibition industry, started a journey of energy conservation and carbon footprint reduction in its Laserplex theaters. Armstrong helped inox replace four constant-speed pumps with three Design Envelope pumps and changed the system to use primary-variable control.
HVAC savings as a result of the retrofit project were over $7,900, which represented a 43% decrease in spending year-over-year. The payback period for the investment in energy efficiency was just 1½ years.
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.
