APC InRow RD Cooling System, a type of cooling unit designed for data centers and server rooms. These units are placed in a row with server racks to cool IT equipment directly. 
* The "InRow RD" system is designed to provide predictable and efficient cooling by capturing hot air directly from the IT equipment, preventing it from mixing with cold air. 

* The system uses a microprocessor controller and an LCD screen to monitor and adjust cooling capacity and airflow. 

* It is a modular and scalable solution, allowing for the addition of cooling capacity as demand increases. 

* The system can be integrated with building management systems to send alarms and data for monitoring critical infrastructure.
