Precision Cooling (CRAC/CRAH)

CRAC (Computer Room Air Conditioner) systems use refrigerant-based DX technology to provide direct cooling, while CRAH (Computer Room Air Handler) systems operate with chilled water heat exchangers connected to a central cooling plant or chiller. Both systems maintain the ideal balance between hot air return and cold air supply, ensuring equipment performance while minimizing energy consumption.

"Proper cooling doesn’t just control temperature; it manages efficiency, longevity, and continuity."

ERFA Information Technologies optimizes precision cooling systems at an engineering level through parameters such as airflow analysis, humidity balancing, filtration, fan control, and Free Cooling scenarios. System performance data is integrated into the DCIM infrastructure, allowing real-time monitoring of temperature curves, humidity profiles, and cooling loads. This ensures both energy savings and long-term hardware safety in data centers.
