The shift to AI and GPU-intensive workloads is driving rack power density to levels conventional air cooling simply can’t handle. At Data Centre World Asia 2025, Delta Electronics unveiled a set of sophisticated power and thermal solutions engineered to meet this extreme demand—highlighting liquid cooling, modular power, and advanced energy storage.
If you’re an engineer or architect designing next-generation facilities, here are the technical highlights you need to know:
Liquid Cooling: The New Standard for High-Density
Delta’s commitment to high-density thermal management was clear, featuring specialized Coolant Distribution Units (CDUs):
- In-Rack Liquid-to-Liquid (L2L) CDUs: Designed for the most intensive GPU/AI clusters, these units deliver cooling capacity of up to a staggering
per rack. This level of density is critical for maximizing performance in limited floor space.
- Containerized Cooling Capacity: Their flagship 20-foot Containerized Data Center featured a state-of-the-art liquid-to-air (L2A) CDU with an impressive
Modular Power & HVDC Efficiency
The challenge of powering these dense racks is solved through modular, high-efficiency systems:
- Scalable Power Train: Delta showcased a new Power Train Unit designed for AI edge applications. Its modular architecture is scalable up to
- HVDC Integration: The AI Containerized Data Center utilizes High Voltage Direct Current (HVDC). By reducing the number of AC-DC power conversion stages, the HVDC design significantly boosts overall energy efficiency and reduces heat generation compared to traditional Alternating Current (AC) distribution.
Rapid Deployment Power Skids
To cut down on project timelines, Delta is pushing prefabricated architecture:
- Power Skid Design: This customizable, high-density platform integrates all essential power components—from switchgear and UPS modules to rectifiers and battery storage—into a compact, factory-tested unit. This is designed for swift, predictable on-site integration, drastically minimizing complexity during the deployment phase.
By moving beyond traditional air-based cooling and standard power distribution, Delta’s new portfolio provides the necessary technical headroom for the inevitable density increases brought on by global AI adoption.
