Customized RDHx
- The maximum capacity is over 30kW.
- Active RDHx works in conjunction with server fans to optimize performance and extend life
- 100% eliminate excessive concentration of server waste heat or poor heat removal
- Provides scalability for future demand growth
- When the active RDHx is integrated with the LCSU (Liquid Cooling Supply Unit), it can provide a gas-liquid cooling solution, which is suitable for the field of ice-free water machine

Note:
- The above evaluation of cooling capacity is based on the conditions of ASHRAE. The inlet air volume of the cabinet is taken @100 CFM/kW, the ambient humidity is 50%, and the inlet water temperature of the back door is set to 18 °C
- (2) The evaluation of the maximum cooling capacity is based on the evaluation data at an allowable ambient temperature of 27 °C
- The evaluation of the minimum cooling capacity is based on the evaluation data at an allowable ambient temperature of 25 °C
- The flow rate of the 30kW back door data test is set to 56.8 LPM, and the flow rate of the 20kW back door data test is set to 45 LPM
