As AI density increases, the role of HVAC coils shifts from being the primary cooling method to being part of a hybrid thermal management architecture — but they’re still fundamental to keeping AI infrastructure operational.

Commercial HVAC coils, especially chilled water and DX evaporator coils, still play a foundational role in cooling modern AI data centers, even as liquid cooling and advanced systems expand.

Coils are a core component inside air handlers and heat exchangers, making them a critical part of the mechanical backbone of AI facilities.

Supporting the AI infrastructure is thermal infrastructure, which includes:

• Chillers
• Cooling towers
• CRAH/CRAC units (Computer Room Air Conditioner) and CRAH (Computer Room Air Handler)
• Heat exchangers
• HVAC coils (DX evaporator and chilled water)

HVAC coils support the massive physical infrastructure required to run AI at scale:

• They move heat away from air
• Support liquid cooling systems
• Stabilize environmental conditions
• Form part of the overall heat rejection chain

DX evaporator coils play a critical role in AI data center cooling by directly absorbing heat from high-density server environments and transferring it to the refrigeration system for removal.

Chilled water coils also play an integral role in AI data center cooling. They transfer heat out of the air (or directly from equipment) into a chilled water loop, which then carries that heat away to be rejected elsewhere.

AI data center growth is surging across the U.S. driving unprecedented cooling requirements. Nationwide Coils is positioned to support the level of quality and engineering that AI data centers demand:

• U.S.-sourced materials of the highest grade
• U.S.-based manufacturing
• Fast lead times
• Expedited build options, including 1-day emergency production
• Highest-quality engineered coil construction
• Protective coating options to safeguard coils long-term in harsh environments. Ask about Energy Guard, Electrofin®, Heresite® and Protecall to protect your coil.
