Walk-in coolers and freezers are the backbone of countless businesses — but they’re also among the largest energy consumers in commercial spaces. At ReFridge, we understand that keeping operating costs under control while protecting your product is a top priority. That’s why we recommend a smart upgrade like the CUES (Chilled Unit Energy Saver) — a simple but powerful solution that delivers long-term savings and sustainability benefits.
What is CUES?
The CUES Chilled Unit Energy Saver is a temperature-based controller that works with your walk-in cooler or freezer. Instead of running evaporator fans 24/7 — even when no cooling is needed — CUES reduces fan run-time by detecting when the box temperature is satisfied and safely slowing down the fans.
The result? You get the airflow you need when you need it — and energy savings when you don’t.
The Long-Term Payoff
Many walk-in owners focus on upfront costs, but the real financial story plays out over months and years. Here’s how CUES helps:
✅ Lower Utility Bills
CUES can reduce evaporator fan energy use by up to 70% in coolers and up to 50% in freezers. That translates into significant cost savings, especially in energy-intensive operations like grocery stores, restaurants, and food warehouses.
✅ Extended Equipment Life
Because CUES cuts down unnecessary fan operation, your system components experience less wear and tear. That means fewer repairs, longer-lasting fans, and reduced maintenance costs.
✅ Reduced Carbon Footprint
Saving energy isn’t just good for your bottom line — it’s good for the planet. Lower power consumption reduces greenhouse gas emissions and helps businesses meet sustainability goals.
✅ Qualifies for Rebates
In many regions, CUES installations may qualify for energy-efficiency rebates or incentives from utility providers, further boosting your return on investment.
Rebate-Eligible Energy Savings
Upgrading to energy-efficient technology like the CUES (Chilled Unit Energy Saver) can do more than lower your utility bills — it may also qualify for energy-efficiency rebates through your local utility provider. Rebates for evaporator fan controllers and refrigeration upgrades are available in many regions, helping you offset installation costs and maximize your return on investment. Check with your energy provider to explore current rebate options in your area.
A Low-Disruption Upgrade
One of the best parts about CUES is how simple it is to install. Unlike major retrofits or system overhauls, CUES can be added to most existing walk-ins with minimal downtime or disruption to your operation. It’s a small upgrade that delivers a big impact — without interrupting your day-to-day business.
