SmoothAir: Rear Door Heat Exchanger

Engineered for Efficiency. Built for Cooling. Trusted to Run.

SmoothAir Rear Door Heat Exchange systems offer a flexible approach to precision cooling; combining high-density heat removal with an intelligent control framework.

The lineup includes two variants: SmoothAir RDHx DX and SmoothAir RDHx CW. The DX version uses a refrigerant-based process to capture heat from server exhaust and transfer it through an outdoor condenser, delivering up to 25.1 kW of cooling capacity without the need for water loops or manifolds.

The CW variant leverages chilled water from a central plant to cool the rear door exchanger. Across three models, cooling capacities range from 31.2 kW to 65.8 kW, supporting higher thermal loads with dependable performance.

SmoothAir RDHx solutions are suited for micro data centres, server rooms, edge computing sites, and high-density racks supporting AI, ML, and GPT workloads. Their rack-level design ensures efficient heat removal with minimal disruption to existing layouts.

Product Features 

  • The flexible piping system allows the door to open normally for quick access to equipment. 
  • The Rear door heat exchanger systems in Africa is designed using modular principles, so it can be expanded without any hassles in future. 
  • It relies on R134A refrigerant with lower working pressure, so it has zero ODP (ozone depletion potential), and lower GWP (global warming potential). 
  • The RDHx is highly efficient as comes with pump refrigerant cooling, inverter compressor, and EC fans. 
  • The heat is discharged directly from the racks, and the high inlet temperature brings maximum energy efficiency. 
  • The heat exchanger is assembled and designed using top-level components, so it can work for a long time without failing. 
  • The smart control systems assist in controlling, managing, and monitoring the unit locally and remotely.
