Maximize the water or energy savings of your eco-cooler with EVAPCO’s Sage® Water and Energy Conservation System! The Sage system operates the eco unit in a manner which maximizes water or energy savings, based on the client's water or energy savings priority.
Manufacturer Supplied and Programmed
Using our patented Sage Control System guarantees seamless integration with your eco unit, reduced field installation times, and maintains EVAPCO as your single-source cooling solution.
Adaptive Control Sequence for Ultimate Savings
The Sage control system can be set to either maximize water or energy efficiency. By measuring and then analyzing real-time load and weather data, the Sage control system switches between various modes of operation, readily adjusting fan speed and switching from dry to evaporative mode as load and conditions require, based on the prioritizing of water or energy savings.
When set to prioritize water savings, the Sage control system varies the unit between dry and evaporative modes of operation in order to minimize time spent in evaporative mode.
When set to prioritize energy savings, the Sage control system varies the unit between dry and evaporative modes of operation, and controls fan speed and pump operation in an effort to maximize energy savings.
Sage 3, exclusively for the eco ATWB-E
In the case of the eco ATWB-E, the Sage control system enables a third mode of operation: water efficient mode. In this mode, the eco ATWB-E runs 50% in wet-mode, 50% in dry-mode, further increasing water efficiency and savings depending on load conditions.
