Over the past few years, we’ve seen a clear shift in data center design:
open racks are being replaced by fully sealed cabinets.

Why?

1.Higher equipment density

2 More sensitive electronics
3 Rising energy costs
4 Demand for stable and predictable cooling

Open racks depend heavily on room-level cooling.
But in real-world operations, this often leads to:

• Hot spots
• Dust and humidity exposure
• Unstable internal temperatures
• Lower equipment lifespan

Fully sealed cabinets, combined with closed-loop cabinet cooling, allow data centers to:

✔ Isolate heat at the source
✔ Protect critical equipment
✔ Improve energy efficiency
✔ Maintain consistent performance

This is becoming a key trend not only in large data centers,
but also in edge computing, telecom rooms, and industrial ICT environments.
