Cooling Architectures for the Next Generation of Compute
Apex Thermal Systems partners with data center owners, operators, and integrators to design and deliver liquid cooling solutions that match workload density, facility constraints, and deployment timelines.
AI Training & Inference Clusters
Modern AI accelerators routinely exceed 700 W per GPU and 100 kW per rack. Air cooling alone cannot sustain these densities without over-provisioning mechanical infrastructure and sacrificing PUE. Apex liquid cooling solutions remove heat at the source and reject it efficiently to the facility water loop or ambient.
Typical Architecture
- Cold plates or direct-to-chip loops on accelerators
- Rack manifolds with redundant supply/return branches
- High-capacity CDU with redundant pumps and heat exchangers
- Dry cooler or facility heat exchanger for heat rejection
Benefits
- Supports rack densities beyond 100 kW
- Reduces HVAC capital and operating costs
- Improves accelerator thermal throttling margins
- Enables warm-water cooling and free cooling
High-Performance Computing
HPC environments demand sustained performance from densely packed CPUs, GPUs, and interconnects. Apex delivers liquid cooling systems that maintain tight temperature uniformity while minimizing pump energy and coolant volume.
Typical Architecture
- Row-based manifolds feeding multiple compute racks
- Centralized or distributed CDUs
- Temperature and flow monitoring per rack
- Integration with job scheduler telemetry
Benefits
- Stable node temperatures under all-core workloads
- Higher FLOPS per square foot
- Lower facility noise and fan energy
- Scales with cluster expansion
Hyperscale Deployments
Hyperscale operators need repeatable, factory-standardized cooling modules that can be deployed across regions rapidly. Apex manufactures rack-level and row-level cooling systems with consistent quality, documentation, and supply chain continuity.
Typical Architecture
- Standardized rack-level CDU skids
- Modular manifold assemblies
- Common spare parts and service kits
- Global documentation and commissioning support
Benefits
- Rapid multi-site deployment
- Consistent performance and serviceability
- Volume manufacturing with short lead times
- Reduced field installation risk
Colocation & Multi-Tenant Data Centers
Colocation providers must support a mix of tenant densities without overbuilding shared mechanical infrastructure. Apex solutions allow targeted liquid cooling where high-density tenants need it, while standard racks continue on air.
Typical Architecture
- Zone-level CDUs serving high-density cages
- Rear door heat exchangers for targeted cooling
- Tenant-specific monitoring and metering
- Leak detection and isolation per zone
Benefits
- Attract AI and HPC tenants without full facility retrofit
- Clear operational boundaries between tenants
- Pay-as-you-grow capacity expansion
- Improved PUE and competitive positioning
Enterprise Data Centers
Enterprise IT teams need reliable cooling that integrates with existing facilities, limited footprints, and conservative operational practices. Apex provides phased liquid cooling upgrades with minimal disruption to live environments.
Typical Architecture
- Rear door heat exchangers on high-load racks
- Small-footprint in-rack or in-row CDUs
- Connection to existing chilled water or dry coolers
- Monitoring integrated with existing DCIM
Benefits
- Extend life of existing data halls
- Avoid full chiller replacement
- Lower total cost of ownership
- Simple maintenance and training
Our Solution Development Process
From initial concept to commissioned system, Apex applies a structured engineering process that reduces risk and accelerates deployment.
Thermal Assessment
We review heat loads, rack layouts, flow requirements, and facility constraints to establish baseline performance targets.
Hydraulic Design
Our engineers model pressure drop, flow balance, and pump selection to ensure every node receives the required coolant flow.
System Integration
We select and configure CDUs, manifolds, RDHx, hoses, and controls into a unified system with single-source accountability.
Manufacturing & FAT
Components are fabricated, assembled, pressure-tested, and cleanliness-certified in our North American facility.
Commissioning
Apex field engineers supervise installation, perform loop balancing, and verify controls, alarms, and monitoring.
Ongoing Support
We provide spare parts, service agreements, remote monitoring support, and future capacity planning.
Hybrid, Direct-to-Chip, or Rear-Door: We Match the Architecture
There is no universal liquid cooling design. Apex supports direct liquid cooling, rear-door heat exchangers, immersion-ready infrastructure, and hybrid air-liquid systems. We help you choose the right approach based on server platform, power density, facility water availability, and operational model.
