Indirect Adiabatic (Pre‑cooling): Fine mist is sprayed onto heat exchanger coils or air intake, cooling the air by evaporation without increasing humidity inside the data centre.
Smart activation logic: Systems operate in “dry mode” most of the time, engaging mist only when outdoor air lacks the capacity to meet cooling load, based on ambient temperature, humidity, and load.
Sensor-driven control: Includes humidity and temperature sensors feeding into PLC controllers; compatible with Modbus or BMS for visible control and expandability.
Compact & modular design: Scalable setups placed externally on rooftops or integrated into AHUs, chillers, or CRAH units without requiring cooling towers.
Water-efficient operation: On-demand misting dramatically reduces water use—85–95% less than traditional evaporative cooling towers.

Substantial Energy Savings: Pre-cooling intake air lowers the compressor’s workload, saving 20–40% in energy compared to conventional air-cooled systems.
High Cooling Capacity in Extreme Heat: Maintains full equipment performance even in ambient temperatures of 45–50 °C, stabilizing high-density data halls.
Water Use Optimization: Consumes minimal water only during peak heat, reducing overall consumption by up to 90% compared to tower-based systems.
Enhanced Equipment Longevity: Cooler, stable inlet air reduces wear on chillers, compressors, fans, and other hardware, improving lifecycle and uptime.
Lower CapEx & Operational Complexity: Eliminates need for water-cooled towers or complex fluid systems; compact modules and dry-mode operation reduce infrastructure costs.
