Lineage Logistics uses Monnit Corporation’s IoT temperature and vibration sensors to cut energy costs and protect billions of pounds in warehoused food.
Food safety is a priority if you warehouse and ship billions of pounds of food destined for Walmart, Costco and local grocery stores in the U.S. Product must be protected in the most energy-efficient way.
This is a daily challenge for San Francisco food processing, warehousing and distribution company, Lineage Logistics, a Top 2 North America temperature-controlled warehousing company with more than 518 million cubic feet of freezer and cooler capacity, serving roughly 20 to 25 percent of the U.S. third-party cold food chain.
IoT Sensors Protect Food and Reduce Energy Costs
Due to the size of their refrigerated warehouses, Lineage was seeing temperature gradients from one side of the warehouse to the other. Doors opening and thermal load from rooftops can cause temperatures to vary outside ooptimal range in some areas of the warehouse. Rather than lowering the temperature of the entire warehouse to account for warm spots, they use Monnit’s wireless temperature sensors to create a heat map of the warehouse and adjust airflow to address the warmer areas without needing to over cool the entire building, providing significant cost savings.
Lineage is also using Monnit vibration sensors to monitor refrigeration compressors, helping them predict issues and avoid high repair costs and compressor breakdowns. Monnit sensors can also prevent another common refrigeration problem called “liquid hammer,” a pressure spike caused when fluid in the refrigeration pipes is forced to stop or change direction suddenly.
Lineage currently uses approximately 1,500 AA battery-powered wireless sensors from Monnit across a few of its facilities, and they look to expand that into many more buildings in the near future.
