Frequently Asked Questions
How much heat can a rear-door heat exchanger remove per rack?
Passive rear-door heat exchangers (RDHx) typically remove 30-50 kW per rack using facility chilled water. Active RDHx units with built-in fans can handle 60-80+ kW per rack. Actual capacity depends on water supply temperature, flow rate, server airflow volume, and exhaust air temperature. RDHx solutions are ideal for mid-density deployments and retrofit scenarios.
Does an RDHx system require changes to existing data center infrastructure?
RDHx deployment requires adding chilled water supply and return piping to each rack location, plus a CDU or connection to the building chilled water loop. No changes to raised floors, ceiling plenums, or CRAC units are required. Existing racks can often be retrofitted by replacing the standard rear door, making RDHx one of the lowest-disruption liquid cooling options.
What coolant flow rate is needed for rear-door heat exchangers?
Typical RDHx units require 15-30 LPM of chilled water per rack at an inlet temperature of 15-20C to achieve rated cooling capacity. Higher-capacity active units may require up to 40 LPM. System design must account for total facility flow requirements across all racks and ensure the CDU can deliver adequate flow at the required supply temperature.
