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.GranBering KW is a low-temperature reach-in merchandiser from Kysor Warren, built for frozen food and ice cream applications.

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.The demand for CO2 systems is outpacing the comfort level many teams have with them.

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. These self-contained cabinets bring the refrigeration system, controls, and display area together in one unit.

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?

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. Both are designed to support better CO2 transcritical refrigeration performance. Both can help retailers move toward natural commercial refrigeration.

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.

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. Warm weather can make CO2 transcritical systems work harder, especially in high ambient conditions. The system still has a job to do - frozen food has to stay frozen, medium-temperature products have to stay safe and appealing.

When the weather gets warmer, you know it changes how you feel. Summer has a way of finding the weak spots in people and in refrigeration technology. A case that ran just fine in March can start sweating, icing, drifting in temperature, or working harder than it should once the store gets busier and ambient temperatures climb.

Space is tight, but timelines are tighter. That’s the reality for many refrigeration projects right now. You’re trying to upgrade equipment, stay compliant with current regulations, and keep the project moving without delays or major disruption. At the same time, the rules for sustainable commercial refrigeration have changed.

There’s a point at which refrigeration stops being a system and becomes infrastructure. You see it in large grocery stores, distribution environments, and multi-location operations. Cooling demand isn’t steady - it shifts throughout the day. One section of the store spikes while another settles, so equipment has to respond without overcorrecting or wasting energy. At the same time, regulations have tightened.
