Chapter 2: Features
2. Features
Chilled water (CW) is supplied to the Cold Row CW unit via a building chiller or other chilled water plant. Chilled water has high
affinity for heat, making it a very efficient cooling method. The E² controller enables independent valve and fan control so the unit
can adjust immediately, and precisely, to varying heat loads and optimize energy efficiency.
Two models are available:

3. Configurations
Open Aisle Configuration
Open aisle configuration organizes racks in a single row or in hot
and cold aisle rows, but without containment. The Cold Row
CW draws hot air from the external environment or hot aisle,
removes the heat, and supplies cooled air to the front of IT
equipment in the cold aisle.
Cold Aisle
Containment with
Front Discharge
Cold Aisle Containment
Cold aisle containment captures cooled air from the Cold Row
CW and prevents it from mixing with hot air. The front of IT
equipment is accessed in the contained cold aisle. The Cold Row
CW draws hot air from the external environment, removes the
heat, and supplies cooled air back into the contained cold aisle.
