Energy waste in a food store rarely presents itself as a single dramatic problem. It hides in equipment that is larger than the load requires, controls that need adjustment, worn door gaskets, blocked airflow, dirty components, and display cases working harder than necessary.

Each issue may seem small. Together, they can place a steady burden on energy use, equipment performance, and operating costs.

Las Vegas is getting ready for NACS 2026, and Kysor Warren will be there.

From October 7–9, the NACS Expo will bring convenience and fuel retailers, suppliers, manufacturers, and industry professionals together at the Las Vegas Convention Center. Kysor Warren will be exhibiting at Booth C3590, giving attendees the chance to meet the team and learn more about commercial refrigeration solutions built around the needs of modern food retail.

Retail refrigeration leaves very little room for a bad fit. A system that is too large can occupy valuable space and add unnecessary complexity. One that is too limited may struggle to support the store’s cooling requirements. Small and medium retailers need a solution that sits comfortably between those two extremes.

That is precisely where Kysor Warren’s new ECO₂Small refrigeration system fits.

Summer means that ice cream moves faster, frozen meals get more attention, and shoppers reach for quick sides, treats, desserts, and easy dinner options.

This, in turn, means that doors open more often and cases have to keep up - and that is where a strong frozen merchandiser earns its place.

CO2 refrigeration is important for many businesses, as retailers are increasingly looking at natural refrigerants, energy-efficient refrigeration systems, and long-term strategies to reduce environmental impact without sacrificing performance. That has pushed CO2 refrigeration into more conversations, more store designs, and more service plans.

That is good news, but it also creates a very real challenge.

Natural commercial refrigeration does not always need a full store conversion, a new machine room, or a major piping project to begin using natural refrigerants. R290 propane plug-in cases give stores a faster route to lower-impact refrigeration while solving everyday problems like limited display space, seasonal demand, changing floor plans, and the need for extra chilled or frozen capacity. 

As strong as your store may appear on the surface, busy seasons have a habit of exposing every weak spot when you least expect it. How often has a promotion needed more chilled space? Or a grab-and-go section has started selling faster than expected? Add in situations where a remodel shifts the floor plan or a department needs extra capacity before the central refrigeration system can be expanded, and you’ll soon see that your store isn’t as resilient as you imagined.

CO2 refrigeration has reached the point where the question is no longer whether it can work in demanding food retail environments, because we already know it can. The better question is how to make it work as efficiently as possible for the store, the climate, the load profile, and the operator’s long-term goals.

And that is exactly where technologies like FTE and ETE matter.

Summer gets most of the attention in commercial refrigeration, and that is fair, as hot weather can cause the most problems for a refrigeration system. Heat makes systems work harder, stores feel busier, doors open more often, and every weakness shows up faster.

But the smartest refrigeration improvements don’t clock out when the weather cools down, and that is why FTE is particularly interesting.

We know that CO2 refrigeration has a lot going for it. It uses R-744 (a natural refrigerant), supports sustainability goals, and helps retailers move away from higher-impact refrigerants while still getting the performance they need from modern commercial refrigeration systems.

Then summer arrives.
