Think Like a Thermostat

Smartcool Energy Saving Device optimizes your A/C, automatically!

Cycle Optimization

A/C and Refrigeration are first designed to profit the manufacturer, leaving unused savings and efficiencies on the table. The Smartcool ECO3 computer “learns” your system and application and then optimizes each cycle to squeeze the absolute highest efficiency possible out of your system. Learn more about compressor cycles, and how Smartcool optimizes them.

Once installed, it continuously monitors the thermostat demands and adjusts each and every cycle for maximum efficiency and savings, all the while maintaining temperature control priority.
