Central Memorial High School creates opportunities for 1100 students to focus on the arts, athletics or trades. In 2018, Armstrong worked with the Calgary board of Education to upgrade the hvac system for better efficiency and comfort.

Armstrong installed four new Design Envelope pumps, plus the cloud-based Pump Manager service for pump analytics. Indoor temperatures are now more comfortable and the replacement pumps use 59% less energy.

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, and Armstrong’s Pump Manager helps maintain and extend efficiency throughout the pump’s operating life.
