Rear Door Heat Exchangers
Passive and active RDHx units that capture server exhaust heat before it enters the aisle, supporting densities beyond 80 kW per rack.
Engineered Thermal Infrastructure for Next-Generation Compute
Apex Thermal Systems designs and manufactures high-performance liquid cooling infrastructure that removes heat where it is generated—enabling higher rack densities, lower PUE, and faster deployment for North American data centers.
Product Portfolio
Every component is engineered to work as an integrated system: coolant distribution, heat capture, connection hardware, monitoring, and safety.
Passive and active RDHx units that capture server exhaust heat before it enters the aisle, supporting densities beyond 80 kW per rack.
Precision CDUs with redundant pumps, intelligent flow control, and built-in heat exchangers for safe liquid cooling at scale.
Stainless steel and aluminum rack manifolds designed for balanced flow distribution across every server node.
Non-spill quick connects for hot-swappable server maintenance and minimal coolant loss during service.
Reinforced, braided, and insulated hoses rated for continuous data center operation and clean routing.
Integrated rack-level cooling that combines manifolds, heat exchangers, and monitoring into a single deployable unit.
North American Manufacturing
Our vertically integrated manufacturing facilities produce CDUs, heat exchangers, manifolds, and hose assemblies under one roof. We control quality, lead time, and customization so your project stays on schedule.

Why Apex
Standard designs ship in 12–24 weeks. Our modular skid approach reduces on-site installation time and commissioning risk.
From custom manifold layouts to full facility heat rejection systems, our applications engineers design around your rack geometry and thermal targets.
We size, simulate, and validate cooling systems for GPU clusters, AI training racks, and HPC workloads up to 150 kW per rack.
Leak detection, pressure monitoring, automatic shutoff, and redundant pumping come standard—not as add-ons.
