CUES — A Commercial Energy Efficiency Solution for Refrigeration

Air cools and warms fast. Food doesn’t. Every fluctuation in air temperature triggers another compressor start — each one drawing a spike of energy, whether the food needs it or not.

How it works

A retrofit device, not a replacement system

CUES is a retrofit device, not a replacement system. It fits directly over an existing thermostat or probe.

Inside, a food-safe wax simulant matches the thermal mass and conductivity of real food. The refrigerator reads that instead of the air around it.

The result is a slower, steadier cycle. Compressor starts drop by up to 80 percent, because the system now responds to food, not draft.

Fewer starts mean fewer energy spikes. Documented energy savings run up to 33 percent on the refrigerated asset.

NSF-Approved, Zero Maintenance

CUES carries NSF Protocol P235 approval for food storage environments.

Installation is simple: no wiring changes, no software, no ongoing upkeep. Once it’s placed, it stays in place.

It works independently of Eniscope and Air Technology, though the three combine well. Add a temperature probe, and CUES can feed food-safety data back into the same cloud platform.

Results Across the Best Energy Network

Safeway tested CUES on a frozen warehouse compressor in Canada, monitored by Best Energy’s partner network. Energy use dropped from 43,174 kWh to 38,111 kWh over a two-week trial, a 12 percent reduction, with payback in three months.

At Kings Point, a Florida retirement community, CUES was one part of a combined retrofit. It included LED lighting and variable frequency drives. Best Energy’s network documented a 35 percent cut in the property’s overall annual energy spend from that combined package.

Refrigeration doesn’t need to run harder than the food demands. It needs to know what the food is actually doing, and react to that, not the air.

Every Cycle You Don’t Fix

Every compressor cycle a refrigerator doesn’t need is a cost that repeats. Not once — every hour, every day, for as long as the unit runs.

That waste is invisible on a utility bill. It only shows up as a total, months after the fact.

CUES fixes the cause, not the symptom. One retrofit, placed once, keeps paying back for as long as the equipment operates.

The Safeway trial paid for itself in three months. That result came from one frozen-warehouse compressor over a two-week trial. It shows what one documented project achieved, not a typical payback period. Kings Point provides a useful contrast. Its combined retrofit was estimated to pay back in four years. The project came in at two years.

Frequently Asked Questions

CUES is the Chilled Unit Energy Saver for commercial refrigeration. It is a retrofit device, not a replacement refrigeration system. It targets unnecessary compressor cycling caused by changing air temperatures.

CUES fits directly over the existing thermostat, thermistor, or probe. Inside, a food-safe wax simulant mirrors food’s thermal behavior. The refrigerator responds to simulated food temperature instead of air.

Air temperature changes quickly whenever doors open or cold air moves. Stored food usually changes temperature much more slowly. CUES helps the compressor follow actual product conditions more closely.

Documented asset-level savings can reach 33 percent under suitable conditions. Actual results depend on equipment, usage, settings, and site conditions. We verify savings through measured performance, not a fixed promise.

CUES can reduce compressor-start frequency by up to 80 percent. Individual cycles may last longer, but they occur less often. Fewer starts reduce energy spikes and may limit equipment wear.

CUES uses food-safe materials inside a protective ABS housing. It carries NSF Protocol P235 approval for food-storage environments. Approval should still be verified for the selected model.

Installation requires no wiring changes, software, or ongoing maintenance. The device stays positioned around the existing temperature sensor. We confirm equipment compatibility and placement before installation.

CUES works independently without the Air Technology LoRa network. A temperature probe can send food-temperature data through Eniscope. This adds cloud visibility without changing CUES’s primary function.

A two-week Safeway trial reduced energy consumption by 12 percent. Usage dropped from 43,174 kWh to 38,111 kWh. That project achieved a three-month payback on one warehouse compressor. It was a partner result, not our installation.

Compatibility depends on the existing sensor, controls, and operating conditions. We review compressor behavior before recommending any refrigeration retrofit. The decision starts with measured conditions, not a generic estimate.
