Liquid Cooling Retrofits Are Hard but Sometimes Worth It
Retrofitting existing data centers for liquid cooling can improve density and thermal efficiency, but space constraints, structural weight limits, and extended downtime make it viable only in select cases.
Key points
- In older facilities, available space is often occupied by network and power cabling, requiring rack repositioning and new coolant routing.
- Fully loaded AI racks can exceed 3,000 pounds, which raised-floor designs may not support without structural reinforcement.
- Structural and mechanical modifications can take months, and even without major building work, the transition from air to liquid cooling involves disruption.
What it means for Iran
Before investing in a liquid cooling retrofit, the real questions are structural capacity and downtime planning, not just equipment procurement.
- Structural limits: If your facility uses raised floors, verify load‑bearing capacity before committing; fully loaded AI racks can exceed 3,000 lbs.
- Downtime risk: Structural and mechanical work can take months; without spare capacity at another site or cloud‑burst options, operational risk rises.
- Physical space: Dense racks often leave insufficient room for coolant supply and return lines alongside existing network and power cabling, forcing costly rack repositioning.
Recommendation: Conduct a thorough structural and thermal assessment of the existing site and develop a detailed downtime plan before any liquid‑cooling investment.
