From Pilot to Fleet: How LSG Sky Chefs Validated eTemp Across 17 Facilities
The Deployment
LSG Sky Chefs, one of the world's largest airline catering providers and a subsidiary of the Lufthansa Group, operates high-volume food production and storage facilities at major airports worldwide. Refrigeration is a critical infrastructure component — not just for energy cost management, but for food safety across every meal served.
The company's North America region ran several pilot tests with eTemp at its Dallas/Fort Worth (DFW) customer service center. Two separate measurement studies confirmed the results. Following the pilot, eTemp sensors were rolled out to 17 additional customer service centers across the region.
LSG Sky Chefs published the results in its own corporate environmental report, describing eTemp as "a thermostat that helps refrigeration units operate more efficiently" by ensuring that "refrigerators are not responding to minor temperature fluctuations and only reacting to significant changes."
"With eTemp in place, the number of refrigeration cycles needed to maintain food temperatures have been significantly reduced, leading to much lower energy consumption."

All figures below are sourced from LSG Sky Chefs' public environmental report documenting the deployment across 17 customer service centers. The first two metrics represent cumulative savings achieved as of the report date; the annualized run rate at full deployment exceeds 1,000,000 kWh per year — the figure recognized by the Energy Manager Today award.
| Metric | Result |
|---|---|
| Energy saved | 547,558 kWh |
| CO₂ emissions reduced | 437 tons |
| EPA equivalency | Equivalent to planting 80.6 acres of pine forest every year |
| Facilities deployed | 17 customer service centers across North America |
| Pilot facility | Dallas/Fort Worth (DFW) — two separate measurement studies |
How LSG Sky Chefs Described the Results
| Effect on refrigeration | "Number of refrigeration cycles needed to maintain food temperatures have been significantly reduced" |
| Effect on energy consumption | "Much lower energy consumption" across participating facilities |
| Effect on food safety | No degradation — the sensor "stops the refrigeration units from being overactive" while maintaining required storage temperatures |
Industry Recognition
Energy Manager Today — Top Project of the Year
The LSG Sky Chefs deployment was recognized as Energy Manager Today's Top Project of the Year, selected from projects across all industries and energy management disciplines. At full deployment across 17 facilities, the fleet conserves over 1,000,000 kilowatt hours annually — with cumulative documented savings of 547,558 kWh published in LSG's own environmental report at the time of announcement.
"This project not only conserves 1,000,000 kilowatt hours per year, but also helps meet critical food safety requirements by focusing on the critical food temperature data. It's a major improvement in a traditionally carbon-intensive industry."
Energy Manager Today Award JudgesWhy This Deployment Matters
Globally Recognized Brand
LSG Sky Chefs is a Lufthansa Group subsidiary — one of the world's largest airline catering companies, serving hundreds of airlines at over 200 airports. Their decision to deploy eTemp and publish the results in their own corporate environmental report represents the highest standard of third-party validation.
Food Safety Compliance at Scale
Airline catering operates under some of the most stringent food safety requirements in any industry. That LSG validated eTemp's ability to maintain temperature compliance while reducing energy consumption confirms the sensor's suitability for any food service environment.
Fleet-Scale Deployment
Moving from a single pilot facility to 17 distributed locations demonstrates that eTemp's performance is replicable across different equipment vintages, facility configurations, and regional conditions — exactly the path that multi-site operators need to see.
