In a perfect world, retailers would employ an on-site service technician to continuously monitor their refrigeration system’s performance. But often this scenario just isn’t feasible. That’s why the emergence of built-in compressor electronics, like Emerson’s CoreSense™ technology, is revolutionizing the commercial refrigeration service paradigm. To learn more, watch the full video here.

Put yourself in the shoes of a refrigeration technician. Your livelihood is, essentially, based on your reputation for consistency. Just one misdiagnosis or system failure can cause operators to lose trust in even the best technician. Knowing the ins and outs of every piece of equipment is a daunting task, but one that can make or break a technician’s career.

Compressor failure is a worst-case scenario in commercial refrigeration applications. For supermarket operators, it can mean massive product losses combined with system maintenance expenses, repairs and compressor replacement. System failures can blemish the reputations of service technicians responsible for proper diagnosis and preventing system faults before they occur.

At the same time, finding skilled technicians who are trained to maintain your specific system requirements is becoming more difficult every day.

That’s why on-board compressor protection and diagnostic controls are essential to ensuring refrigeration reliability. Designed with advanced communication capabilities, CoreSense technology allows contractors and technicians to accurately diagnose and troubleshoot systems issues, either at a customer’s site or remotely via mobile device access.

In the foodservice sector, operators are shifting their business structures to provide more fresh food offerings and on-the-go meals. As a result, their refrigeration requirements are growing — and becoming more complex.

With CoreSense Diagnostics, technicians can quickly access easy-to-interpret fault codes and remove the guesswork from troubleshooting. CoreSense modules can link to store supervisors and facility management systems, enabling remote monitoring of system conditions, proactive maintenance, scheduling and precise identification of issues — even before technicians are assigned to fix them. In many cases, a technician can identify the issue at hand and identify the necessary parts and tools before they begin the service call.

The value of a skilled HVACR technician cannot be underestimated, but even the best ones will occasionally make mistakes. With CoreSense, Emerson provides technicians and operators alike with the technology that can help reduce misdiagnoses and prevent system failures.

Restaurant and convenience store landscapes are facing unprecedented market pressures and increasing demands to meet consumer expectations. Consumers are seeking fresh, sustainably sourced food offerings from providers that emphasize eco-friendly practices from farm to fork. Pair those demands with pressure to reduce operating expenses while also maintaining regulatory compliance and you have a stressful situation.

Making the move toward outdoor condensing units (OCUs) may be able to alleviate some of that stress. Modern OCUs can help solve a myriad of operational challenges and are emerging as a preferred option for store and enterprise operators.

Compared to legacy OCUs, modern remote systems can deliver annual efficiency improvements of up to 20 percent or more. Modern OCUs can also create a better, more desirable indoor environment for consumers, improving indoor comfort levels by lightening the load on air conditioning (AC) systems, reducing refrigeration noise, and reclaiming space that would be occupied by a centralized rack.

Modern OCUs are engineered to address today’s regulatory challenges as well, maximizing energy efficiencies and meeting the requirements set by the Department of Energy (DOE). These OCUs also utilize low-global warming potential (GWP) refrigerants and keep refrigerant charges to a minimum.

With built-in compressor electronics, modern OCUs provide operators with peace of mind knowing that their equipment is functioning properly and reliably. System faults are immediately communicated to service technicians to help them quickly — and remotely — diagnose conditions and expedite the service process. Advanced diagnostics and smart algorithms, connected to a facility management/control system, provide operators and technicians with early detection alerts, evaluate key performance indicators, help prevent compressor failure and more.

While there are clear and present benefits to using modern OCUs, there are still considerations to be made before making the switch. Physical constraints are typically prevalent when determining whether to invest in OCUs. Some examples of these constraints are: installation in a leased building where drilling holes in the wall/ceiling is prohibited; unachievable access to the outside for remote installation; and difficulty moving equipment in an inflexible layout. There are also cost considerations to be made, such as whether low first costs or lower total cost of ownership are more important.

Sustainability targets, total store energy usage and regulatory compliance are all important factors in the modern refrigeration equation. Modern OCUs can deliver on all these factors, including enhanced reliability, improved installation flexibility, protection against system failures and much more. All of these benefits add up to a lower total cost of ownership compared to other traditional refrigeration methods.

The case for modern OCUs is strong and could take your operation to the next level.
