ECO3

The Smartcool ECO3 is a retrofit energy optimization device designed specifically for HVAC, refrigeration, and heat pump systems, targeting compressor efficiency to reduce electricity consumption without compromising performance. It functions as an intelligent secondary controller that sits between the system’s existing controls and the compressor, dynamically adjusting compressor run times to minimize unnecessary operation. By optimizing the compressor cycle while still maintaining the system’s setpoint temperatures, the ECO3 helps users reduce energy usage without replacing or overhauling existing systems. This makes it a particularly appealing option for facilities that operate older or cost-intensive cooling systems where full system upgrades may not be financially feasible. The ECO3 comes in models for both single and dual-compressor configurations, is easy to install, and is compatible with standard HVAC-R equipment and control protocols. Real-world applications have reported savings ranging from 14% to over 30%, depending on the system’s baseline efficiency, operational load, and maintenance conditions. For instance, hotels, supermarkets, and data centers using ECO3 have achieved substantial energy reductions with relatively short payback periods—sometimes under 12 months.
