With the rapid expansion of AI and high-performance computing (HPC), data centers are experiencing unprecedented increases in heat density. Cooling infrastructure must evolve to support rack densities exceeding 30–80 kW while maintaining energy efficiency and system reliability.
RefriCore delivers advanced finned-tube heat exchanger coils engineered specifically for:
Rear Door Heat Exchangers (RDHx)
Computer Room Air Handlers (CRAH)
Our solutions provide a robust and scalable thermal management foundation for next-generation AI data centers.
RefriCore coils are designed to operate as the core heat transfer component in RDHx systems, where server exhaust air is directly cooled before re-entering the data hall.
Key roles:
Air-to-water heat exchange at rack level
Reduction of hot aisle temperature
Extension of air-cooling viability in medium-to-high density racks
Typical use cases:
AI clusters (20–50 kW per rack)
Hybrid cooling deployments
Retrofit of existing data centers
In CRAH systems, RefriCore coils function as high-efficiency chilled water cooling coils, ensuring stable environmental control across the entire data hall.
Key roles:
Precision temperature and humidity control
High-capacity air-side heat removal
Integration with chilled water loops
