Cabinet Differential Pressure Control
Unlike the majority of rack coolers that have fans coupled closely in series with the IT equipment, the ECHO system ACEs are fitted with the Cabinet Differential Pressure Control (CDPC) system, which allows the differential pressure across the IT equipment to be monitored and controlled to achieve:
- Positive air pressure at the server inlet
- Negative air pressure in the rear of the cabinet at the server outlet, to prevent backwash of hot air
- Controlled differential pressure across the IT hardware so that air is not ‘forced’ through the IT equipment
