Grocery store chain owners and managers are embracing Internet of Things (IoT) technologies to monitor the performance of their refrigeration equipment. I was recently interviewed by ACHRNews (the News) to discuss how IoT is transforming supermarket operations; this blog is a summary of that article.

Supermarkets Embrace IoT Revolution

When it comes to refrigeration equipment, supermarket operators are primarily concerned about reliable performance. With an aging generation of qualified contractors retiring and a growing shortage of trained technicians to replace them, ensuring reliable performance is becoming more difficult. It’s not surprising that as a result, grocery store owners and managers are embracing the potential of IoT to proactively monitor the performance of refrigeration equipment.

IoT is helping to fill the technician void by allowing store managers to take immediate action when refrigeration problems arise. Unplanned downtime can be extremely costly, and IoT gives operators the ability to head off issues before they become potential emergencies.

With IoT, supermarket managers are equipped with the knowledge to make quick repairs and prevent future errors, both of which deliver critical benefits that directly impact a store’s profitability and brand reputation:

  • Increased refrigeration system uptime
  • Reduction in revenue and inventory losses
  • Assurance of food safety and quality

Emerson’s ProAct™ Enterprise Software and Services is a leading example of robust IoT technology at work. Utilizing our Site Supervisor facility management controller and connected refrigeration equipment via sensors to cloud-enabled data analytics, ProAct provides alert and setpoint management while allowing grocers to take a more reliable, cost-effective, condition-based maintenance approach to refrigeration — and seamlessly transition to complete facility management of critical systems in individual stores and across the enterprise.

In this way, IoT uncovers deeper insights into how a facility is running, giving store managers the tools to take proactive measures to ensure reliability, maximize energy efficiencies, and consistently deliver optimum food quality and safety.

From an enterprise perspective, IoT allows store operators to compare trending and historic performance data at multiple sites to better optimize a grocery chain’s complete store network. Operators can also evaluate equipment upgrades and retrofits to determine which systems deliver the best performance and determine if there are any opportunities for cost savings.

Having access to preventive maintenance and predictive failure alerts is beneficial to store owners and contractors alike. Instead of performing preventive maintenance at pre-determined time intervals, IoT triggers maintenance activities based on actual system performance — giving contractors critical information to help them decide when to perform service before failures occur.

Connected refrigeration equipment also helps operators and contractors identify other indicators of asset health, including: spikes in energy use, increased compressor vibration and excessive noise — all signs that equipment could soon be at risk for failure. Not only can IoT prevent costly refrigeration downtime, it can also reduce the need for expensive emergency service calls.

For the newer generation of service contractors, IoT provides a plug-and-play capability that helps overcome their knowledge gap. With the abilities to collect and store all system-related information, IoT helps replace contractor reliance on the intelligence passed down from older contractors who are approaching retirement.

Today’s c-store operators are deploying facility management control systems to meet customer demands for eco-friendly initiatives and improve energy efficiencies. This blog is based on a recent article that described how United Dairy Farmers utilizes Emerson’s Site Supervisor to achieve these goals.

Going Green Helps C-Stores Grow Bottom Line

Appealing to eco-conscious consumers is driving c-stores to implement more sustainable practices. From product offerings and water usage to lighting and energy consumption, c-stores are instituting numerous environmentally friendly initiatives, which are not only attracting customers but also reducing operating costs. United Dairy Farmers (UDF) has experienced the benefits of this strategy firsthand.

With nearly 200 locations in Ohio, Kentucky and Indiana, UDF’s commitment to energy efficiency has produced dividends to their bottom line. This initiative began nearly two decades ago when UDF’s engineering consulting firm, Springridge Partners, installed an Emerson control system in each store to monitor the performance of HVAC, refrigeration and lighting systems. The control systems were set up to alert UDF store managers of any operational concerns, allowing them to take fast preventative maintenance actions and avoid full system failures — thereby saving on product loss, energy and labor costs.

By creating refrigeration setpoints and alarms, store managers receive alerts when a refrigeration system is not operating properly. For example, if case temperatures exceed setpoints, the control system sends an alert to the store manager and maintenance staff, who can then dispatch the appropriate personnel to fix the issue. If compressor temperatures rise or the amperage increases over a short period of time, the system sends alerts of potential compressor failure, giving managers the opportunity to proactively replace it before a downtime incident occurs.

The control system allows UDF and Springridge Partners to determine how much energy the chain is using and make necessary adjustments. One of the first efficiency initiatives they implemented was upgrading the stores’ lighting fixtures to all-LED lighting. Each upgrade of an older UDF store from T-12 florescent lighting to LED delivers nearly 75 percent savings on lighting costs. LED lighting upgrades also reduce associated maintenance and labor costs because lights don’t have to be changed nearly as often.

Recently, UDF upgraded to Emerson’s new Site Supervisor facility control platform in its newest store location in Sharonville, Ohio. This upgrade allows UDF to remotely view the store’s energy usage and investigate consumption variances in real time. Technicians can simply log in to see what’s happening at the store, and then talk to the store manager to decide whether they need a service call. This process also allows employees to make the best use of their time instead of responding to a false alarm.

“The new Emerson Site Supervisor is a continuation of our strategy to integrate technology into our operations. This particular technology will allow our team to be more proactive in addressing issues before they become emergencies, and it allows us to maintain the quality of our products at a very high level,” said Brad Lindner, UDF’s CEO.

What’s more, the system is expected to assist UDF in its plans to implement further reductions in energy usage across its operations.

“By allowing our team to analyze the trend data, we are able to make intelligent decisions regarding setpoints, equipment selections and food quality. We will continue to look for new ways to leverage technology in other areas of our business to increase both awareness and engagement of our staff as a whole,” Lindner said.

Emerson Commercial & Residential Solutions

Emerson recently completed a research study of leading food retailers to better understand their refrigeration system selection criteria. This blog is a synopsis of those findings.

Copeland

For several years, we’ve seen an evolution of the traditional supermarket concept, driven by a convergence of multiple market influences which include:

  • The migration to urban areas
  • Smaller store footprints
  • Renewed focuses on safety and freshness
  • Greater need for merchandising flexibility
  • The proliferation of omnichannel fulfillment models
  • The lack of qualified service technicians
  • Energy-efficiency goals and sustainability initiatives
  • The internet of things (IoT)
  • Ongoing regulatory uncertainty

Amidst these many changes, refrigeration systems have also evolved to align with modern supermarket operator preferences. To better understand how these preferences are impacting selection criteria, we recently completed a research study of several leading food retailers. We asked them which factors they feel are the most important when considering the implementation of new refrigeration systems.

We compiled results into six key categories, which we refer to as the six S’s of selection criteria. The following is a summary of those findings:

  1. Simple — Operators are seeking to minimize complexities by using systems that are easy to understand and diagnose. Many associate system simplicity with reliability and believe it can be achieved with fewer moving parts, traditional system architectures and proven refrigeration strategies.
  2. Serviceable — Technician familiarity is important to facilitate ease of service and maintenance activities, and to ensure the availability of parts and refrigerants. Engine rooms should be located away from customers and be relatively easy to access.
  3. Secure — Maintaining customer, employee and technician safety while preserving food quality and safety are always top priorities. With many operators now integrating IoT technologies for more effective facility and enterprise management, securing proprietary operational data is also critically important. Operators seek system architectures that can address these multifaceted safety and security concerns.
  4. Stable — Grocers consistently cite system stability and reliability as primary selection criteria. Systems should be capable of maintaining consistent temperatures, delivering predictable performance, and working according to design specifications.
  5. Smart Electronic controls, system connectivity and integration with facility management services via IoT are becoming more important to modern supermarket operators. They’re evaluating self-monitoring systems that give store managers immediate access to issues, allowing them to take prompt actions to protect shoppers, preserve their brands and prevent unnecessary service calls.
  6. Sustainable — For those supermarket operators driven by corporate sustainability objectives or regional regulatory requirements, the push toward lower-GWP refrigeration strategies is continuing in earnest. Sustainability also speaks to the long-term economic viability of the refrigeration selection, as operators must factor in the total cost of ownership throughout the lifecycle. Reducing energy consumption to minimize operating costs is a concern shared by all.

As refrigeration technologies evolve in response to changing market dynamics, look for emerging system architectures that align with these selection criteria. Emerson is addressing the six S’s of supermarket operator concerns by innovating new systems that blend pieces of proven architectures — borrowing from what has worked in the past and improving upon existing technologies. Stay tuned for more information on these new system strategies in the months to come.

I recently sat down with the staff of The NEWS to record an episode of The NEWSMakers podcast, where we discussed the state of commercial refrigeration and its role within the larger food supply chain. Our conversation covered a wide range of topics, from regulations and changing consumer preferences to the Internet of Things (IoT) and cold chain temperature monitoring. What follows is a summary of that conversation.

Beyond Iot to digital transformation in the modern supermarket

Regulatory landscape

The impacts of federal and state regulations continue to be felt. While recent rulings have vacated some of the Environmental Protection Agency’s (EPA) previous refrigerant regulations, California is not only maintaining those guidelines, it’s introducing additional mandates for more stringent requirements when dealing with hydrofluorocarbon (HFC) refrigerant use, charge limits and leak detection. Department of Energy (DOE) energy-efficiency regulations remain in effect and are driven by equipment class and size; it’s important for manufacturers and end users to understand how these energy targets impact their specific applications. In addition, there are standards to ensure the safe operation of equipment and preserve food safety.

Changing consumer demands

The market has changed dramatically in recent years, primarily driven by shifting consumer preferences. Some examples include: convenience stores evolving to provide higher-quality, fresh food items; fast-casual restaurants offering home delivery; and grocery stores adding Click and Collect, online shopping options. These business models are placing new pressures on retailers to consistently provide the highest-quality products. If a consumer has a bad experience, then word of mouth quickly spreads, which may damage the offending store’s reputation.

IoT impacts

The prevalence of electronic controls and equipment connectivity via IoT is influencing the entire HVACR industry. In commercial refrigeration, controls are being developed and utilized to meet regulations and ensure product safety and quality. Cold chain technology is now available to monitor and track the condition of food in real time — from the farm to the storage facility to its retail destination — to determine if correct temperatures are maintained. This connectivity helps businesses make real-time decisions. If they see temperatures drifting out of preferred ranges, they can divert shipments to the nearest retail location or recall them altogether.

The abilities to monitor equipment and see its performance at any given time are also impacting maintenance procedures. With modern controls, it’s now possible to monitor system health and detect trends well in advance of a potential failure. This allows end users to better schedule their maintenance activities and prevent equipment failures — especially ahead of peak sales opportunities, such as holiday weekends or new product introductions or menu items.

Security concerns

Anytime you’re creating an unsecured internet pathway to sensitive information, there’s always a concern. But there are options to avoid these challenges. One simple solution is built-in cellular modems on equipment, allowing each piece to act independently from the system containing information. It’s also important to understand that different applications may require different solutions, depending on which services are available in a particular location. We recommend consulting with a network security professional within your region to develop a program that best suits your individual needs.

Emerson’s response to cold chain challenges

Emerson is looking at the cold chain from a holistic perspective — from the time food leaves the farm to when it hits the fork — and we’ve reorganized our entire organization to support the various affected stakeholders. Through strategic acquisitions and the continued development of new technologies, we can monitor and preserve food quality along every step of food’s journey. We’re making IoT-enabled, smart equipment to allow customers to diagnose the health of equipment and see its historic and real-time performances. And, we have comprehensive services that provide enterprise-wide monitoring of mission-critical systems across a network of stores, prioritizing alarms and fixing potential issues before they become problems.
