Consistency, Control and Cost ROI: A blueprint for improving cooler fleet management

In a 60-day controlled comparison field trial in Argentina, AoFrio INSIDE delivered a 47% reduction in daily cooler energy consumption, with compressor runtime dropping by roughly a third. Financial modelling pointed to over 7x ROI on service maintenance costs at scale, creating a compelling business case.

Not every bottler comes to AoFrio with the same problem. In Argentina, our customer’s primary concern was cooler performance and management. Running a large point-of-sale fleet means contending with a wide range of environments, operators, and power conditions, and this beverage bottler needed greater confidence that their coolers were performing as intended, wherever they were deployed.

Unauthorized access to cooler operations was a real and recurring issue. Without a reliable way to enforce how and when cooler settings could be adjusted, asset management became difficult to standardize across the fleet.

Compounding this, inconsistent power supply at many retail locations was creating unpredictable performance and wear on components that shortened equipment life. All this translated into higher service and maintenance costs, which were eating straight into margins.

Our Argentinian customer wanted a hardware solution that could bring these issues under control. AoFrio had one.

AoFrio INSIDE is an integrated hardware bundle featuring the ECR 2 motor paired with the SCS controller. Rather than addressing individual symptoms, the bundle is designed to work as a system, targeting the full range of operational challenges we had identified.

The SCS controller brings motor lockout functionality, restricting operation exclusively to commands through the S1/ S2 ports. That means no unauthorized activation, giving asset managers the hardware foundation they need to take control of their fleet through AoFrio iQ.

The ECR 2 motor handles voltage instability without complaint, maintaining consistent cooling output even where power supply is unreliable. It also runs quieter than legacy motors, which matters at busy point-of-sale locations where the customer experience counts.

The ECR 2 also operates in a Variable Speed mode, auto-matically adjusting fan speed on both the evaporator and condenser in response to real-time thermal demand. This means the motor can work harder when conditions require it, and scale back when demand eases, reducing energy consumption without compromising temperature performance.

On the maintenance side, the ECR 2’s reverse airflow self-cleaning capability keeps condensers clear without manual intervention. Combined with the motor’s reliability, it significantly reduces the frequency and cost of service visits.

To build a robust business case, AoFrio and the Argentinian bottler ran a tightly controlled 60-day trial using a MT-19 cooler at an active point-of-sale site. For the first 30 days, the cooler ran with AoFrio INSIDE installed. For the second 30 days, it reverted to the original equipment configuration.

The findings were compelling:

1. Nearly half the energy, same performance. Independent testing confirmed that AoFrio INSIDE cut daily energy consumption by 47% — dropping from 3.2 kWh to 1.7 kWh — without any compromise to cooling performance.
2. Reduced compressor runtime for an extended equipment life. Testing showed compressor runtime fell from 31% to 19%, meaning less mechanical stress, fewer breakdowns, and a significantly longer equipment lifespan.
3. A cooler, more stable system. Condenser temperatures dropped by 24% during testing, reducing heat stress on the unit and pointing to lower maintenance costs and greater long-term reliability.

780% Return on investment

AoFrio modeled what the trial results would mean if AoFrio INSIDE were deployed across a full 10,000-unit cooler fleet.

Based on typical annual spend, we calculated that our customer in Argentina could achieve a 780% ROI on service and maintenance costs, with the hardware investment paying back in 1.1 years. This equates to total savings of as much as USD$132,000 per year.

One of Argentina’s largest beverage companies came to AoFrio looking for better control over their cooler fleet. AoFrio INSIDE delivered on the core brief – unauthorized access, voltage stability, more efficient operation – with energy savings and a maintenance cost reduction that make the investment case hard to argue with.

With the trial data in hand and a modelled ROI of more than 7x, our customer has everything needed to move from proof of concept to fleet-wide deployment with confidence.
