Data centers demand nonstop performance. With rising power densities and sustainability targets, cooling systems need to be more efficient, more reliable, and more adaptable than ever before. API Heat Transfer delivers advanced aluminum cooling solutions designed to support mission-critical infrastructure while reducing energy use and maximizing uptime.
From air-cooled coils to immersion cooling, API’s engineering and manufacturing expertise make it possible to meet today’s requirements while preparing for tomorrow’s challenges.
Areas of Expertise
API Heat Transfer supports a full spectrum of data center cooling strategies—from traditional CRAH units to next-generation direct-to-chip and immersion systems.
Air-Cooled Solutions
Applications include:
Cooling tower open-loop isolation
Free cooling with air or water
Chiller bypass and air-cooled chillers (ACC)
CRAH chilled water coils, fan wall coils, and condenser coils
Edge Cooling
Applications include:
Shell-and-tube heat exchangers
Refrigerant cooling and condensation
Backup generator cooling (on-engine or remote)
In-row and rear-door chilled water coils
CRAC condensers and evaporators
Direct-to-Chip Cooling
Applications include:
CDU heat exchangers and shell-and-tube systems
Waste heat recovery solutions
Adjacent air-cooling module coils
Dry coolers and V-Bank systems
Custom integrated cooling packages
Immersion Cooling
Applications include:
Dielectric fluid or water-glycol cooling loops
Tank cooling integration
Two-phase fluid cooling and condensation
Dry coolers and V-Bank configurations
Waste heat recovery systems
T-BAR™ Aluminum Technology
A core differentiator for API is its vacuum-brazed aluminum T-BAR™ technology, designed to replace traditional copper-tube/aluminum-fin coils.
Advantages of T-BAR™:
All-aluminum construction eliminates copper price volatility
Up to 50% less fluid volume required compared to copper tube coils
Higher heat transfer efficiency in a smaller footprint
Lighter weight (both dry and wet)
Same performance at warmer chilled water temperatures (3–5°F higher), reducing chiller load
Fan power savings of 20–60%, depending on configuration
The result: higher efficiency, lower costs, and extended equipment life.
