SmoothAir: Rear Door Heat Exchanger

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

The SmoothAir – Rear Door Heat Exchange systems is a flexible, precision cooling solution. It comes with a direct expansion system, high-density cooling capacity, and a smart controller system.  

It comes in two different variants: SmoothAir RDHx DX and CW type. The SmoothAir RDHx DX (Direct Expansion) uses refrigerant-based cooling, where the refrigerant absorbs heat from server exhaust and releases it through a condenser coil, typically connected to an outdoor unit. The total cooling for DX rare door heat exchanger systems is 25.1kW. 

The DX-based design doesn’t need complex water loops and no manifolds, which means simple installation and lower risk of leaks and water-related failures. 

However, the SmoothAir RDHx CW (Chilled Water), which uses the cold water from a central chiller plant to cool the rear door heat exchanger. For the three models, the total cooling ranges from 31.2℃ to 65.8℃. 

You can purchase SmoothAir heat exchanger systems for micro data centers, small to large server rooms, edge computing environments, and other high-density IT spaces where efficient, rack-level cooling is essential. This system can work seamlessly with HPC racks to handle AI, ML, and GPT applications. 

Product Features 

  • The flexible piping system allows the door to open normally for quick access to equipment. 
  • The Rear door heat exchanger systems in UAE 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.
