Background

A restaurant had a 12’ x 12’ walk-in freezer. Pulse was installed to track and record the current draw of the outdoor condensing unit in order to monitor efficiency and detect abnormalities.

Measurements:

Pulse detected that the average current draw had risen by 22%, reaching 17.90 amps on average. To confirm this was not a random variation, Pulse monitored the system for 3 days before issuing an alarm.

Analysis:

The Pulse monitoring device gathered the following data:

  • Significant and sustained increase in current draw
  • Duration of elevated energy use exceeding 3 days
  • Comparison to baseline average current draw levels

Outcomes/Conclusion

Pulse determined a specific type of hybrid on demand system and storage tank that was the most cost effective solution. They now use this system in all their restaurants We found which locations used the least amount of hot water and adapted the use habits at other location.
PULSE provided:

 

  • Insights into which types of dishwashers and dish spray nozzles were most water-efficient.
  • Tested equipment helped determine the models that used the least amount of hot water without compromising performance.
  • Upgraded installations were rolled out across all White Spot locations based on these findings.
