As someone managing small server racks and edge setups, I recently tried the SmoothAir Rack Cooling by Attom Technology — and honestly, it surprised me in the best ways.
🔧 Flexible Designs for Real-World Racks
The system comes in three types:
T Packaged: Mounts on top of the rack. No U-space taken, plug-and-play, ideal for tight spaces.
Bottom Packaged: Sits at the rack base (8U). Air-cooled, no drainage needed — very maintenance-friendly.
Rack Split: Higher capacity with the compressor placed outside for low noise. Great for slightly larger setups.
No matter your rack setup, there’s a version that fits without forcing layout changes.
❄️ Cooling That Works — and Saves Energy
What stood out:
Inverter compressor + EC fans: Adjusts speed automatically to match load. Quiet and energy-efficient.
Eco refrigerant (R410A): Fast, safe, and green cooling. I ran 2 GPU workstations, and temps dropped below 26°C in minutes.
Good airflow: Even in standard racks, it worked smoothly with existing hot/cold aisle arrangements.
📡 Smart Monitoring = Peace of Mind
This isn’t a dumb cooler — it’s smart:
Supports Web, SNMP, Modbus, BACnet, Email, etc. Easy to monitor remotely or integrate with BMS.
Logs 7 days of temp/pressure history. Very helpful for troubleshooting.
Custom alarms and dry contacts — feels like an IT-aware device, not just a cooling box.
⚠️ Things to Watch Out For
Cold environment? Below -15°C needs an optional kit.
Max power: 12.8kW. If you're running dense AI racks, look at their Rear Door Cooling option instead.
Lots of protocols = a slight learning curve if you’re new to integration.
✅ Final Thoughts
If you're running a small-to-mid rack, care about energy efficiency, and need remote control, SmoothAir is a smart choice. It’s compact, smart, quiet, and reliable.
I’ll likely upgrade my other racks soon. It’s the kind of system you install — and forget, because it just works
