Flint’s SmoothAir – Rear Door Heat Exchanger
Rear Door Heat Exchanger | KSA & UAE
High-Density Cooling for AI, ML & HPC Workloads
Flint’s SmoothAir – Rear Door Heat Exchanger is a next-generation cooling solution engineered for high-density racks and HPC environments. Designed with direct expansion (DX) technology, high efficiency, and a smart control system, it delivers seamless thermal management for racks running AI, ML, GPT, and advanced computing applications.
Its flexible, modular design allows smooth integration with existing IT racks, ensuring optimal cooling performance without the need for complex water loops or separate hot/cold aisle segregation.
Flexibility
- Compatible with any standard rack.
- Flexible piping allows racks to open normally, ensuring easy access to equipment.
- Seamless integration with IT racks – simple transport and installation.
- Modular architecture supports scalable expansion for future growth.
Efficiency
- High-efficiency cooling with refrigerant pump free cooling, inverter compressors & EC fans.
- Uses green refrigerant R134A:
- Lower working pressure.
- Zero ODP (Ozone Depletion Potential).
- Lower GWP (Global Warming Potential).
- Removes heat directly from the rack, minimizing recirculation and maximizing energy efficiency.
Reliability
- Built with top-tier components for long life and dependable operation.
- DX-based design eliminates need for complex water loops or manifolds.
- Advanced smart control system enables local and remote monitoring of key parameters.
Ideal for High-Density Applications
As demand for data storage and computing power rises, traditional cooling systems struggle with increasing rack heat densities. Flint’s SmoothAir RDx solution, mounted as a rear radiator door, efficiently transfers heat away from servers, ensuring stable, optimal rack temperatures – even under extreme computational loads.
