Abatigo addresses a major data center cooling challenge - providing the performance of an evaporative system with the advantages of a dry cooler system. The adiabatic coolers drastically reduce water usage - by up to 95% vs. an open cooling tower and up to 60% vs. closed cooling tower - all while maintaining premium energy efficiency and meeting the stringent demands of mission critical design.
Abatigo is a patented closed-loop adiabatic dry cooler that often operates without consuming any water - activating the adiabatic system only on hotter days to pre-cool incoming air. Great for locations with high water costs or low water availability, Abatigo coolers are the ideal replacement for inefficient cooling towers.

Adiabatic technology working principle
As the video demonstrates, for the majority of the year the system performs as a dry cooler, modulating the fan speed to maintain the process leaving water temperature within the design range. During high ambient temperature periods, when the leaving water temperature reaches the maximum process temperature with fans running at full speed, the adiabatic mode is activated and it works as follows:
High-temperature ambient air passes through lower adiabatic chamber.
Inside this chamber, nozzles spray the coil with a fine mist of water from a separate source.
The air is cooled due to humidification, prior to contact with heat exchangers.
The chamber’s design prevents any water drift outside the chamber when the cooled air travels to the heat exchanger.
Digital control system continuously adjusts the amount of water sprayed to ensure consistent cooling.
During extreme peak weather conditions, the optional adiabatic booster feature provides a supplemental cooling function. During booster mode, a portion of the coil surface is flooded and constantly "washed" by a uniform water flow until the booster function is deactivated.
