Product Portfolio

Liquid Cooling Infrastructure, Engineered to Scale

From rear door heat exchangers to complete rack-level liquid cooling solutions, Apex Thermal Systems manufactures the components and integrated systems that keep AI, HPC, and enterprise data centers operating at peak efficiency.

Data Center Cooling Products

Every product is designed for thermal performance, hydraulic compatibility, and long-term reliability under 24/7 mission-critical operation.

Rear Door Heat Exchangers (RDHx)

Passive, high-capacity door-mounted heat exchangers that capture server exhaust heat before it enters the hot aisle. Available in passive and active configurations up to 80 kW per door.

  • Up to 80 kW heat rejection per door
  • Passive or active fan-assisted models
  • Compatible with standard 42U/48U racks
  • Reduces or eliminates CRAH dependency
CDU

Coolant Distribution Units (CDUs)

Intelligent pumping and heat exchange skids that regulate coolant flow, temperature, pressure, and quality across multiple racks. Engineered for AI clusters and enterprise deployments.

  • Capacity ranges from 100 kW to 1.5 MW
  • Redundant variable-speed pumps
  • Integrated filtration and degassing
  • Modbus/BMS connectivity

Liquid Cooling Manifolds

Precision-machined supply and return manifolds for rack, row, and facility-level coolant distribution. Designed for balanced flow across every server node.

  • Stainless steel, aluminum, or titanium options
  • Custom port spacing and termination
  • Isolation valves per branch
  • Leak-tested to 1.5x operating pressure

Quick Disconnect Couplings

Non-spill quick disconnect couplings engineered for safe, tool-free service of servers, manifolds, and CDUs. Dry-break design protects electronics and coolant quality.

  • Dry-break, non-spill operation
  • Single-handed connect/disconnect
  • Pressure ratings to 10 bar
  • EPDM, FKM, and FFKM seal options

Liquid Cooling Hoses

Flexible, kink-resistant hoses rated for data center coolants and operating temperatures. Available pre-assembled with quick disconnects, elbows, and strain relief.

  • Smooth-bore EPDM or PTFE liners
  • Braided stainless steel reinforcement
  • Operating temperatures -40°C to +120°C
  • Custom lengths and fitting orientations
CDU

In-Rack Cooling Systems

Fully integrated rack-level cooling systems combining manifolds, CDUs, heat exchangers, and monitoring into a single factory-tested enclosure.

  • Pre-configured and factory-tested
  • Scales from single rack to multi-rack rows
  • Hot-swappable redundant pumps
  • Integrated leak detection and controls

Dry Cooler Systems

Air-cooled heat rejection systems for liquid cooling loops where water consumption or mechanical cooling must be minimized. Available with fixed-speed or EC fan arrays.

  • Capacities from 100 kW to 2 MW
  • Low-noise EC fan options
  • Free-cooling compatible
  • Galvanized steel or aluminum construction
SENSOR HUB

Thermal Monitoring Systems

Sensor networks and software dashboards that provide real-time visibility into inlet/outlet temperatures, flow rates, pressures, and rack-level thermal health.

  • Real-time dashboard and alerting
  • Modbus, SNMP, and API integrations
  • Trending and capacity planning reports
  • Custom threshold and alarm workflows
ALERT

Leak Detection Systems

Cable, probe, and point-detection leak sensing systems that continuously monitor containment, subfloors, manifolds, and rack bases for coolant presence.

  • Addressable leak detection cable
  • Probe and spot sensors
  • Immediate relay and BMS alerts
  • Zone isolation valve integration
CDU

Complete Rack-Level Liquid Cooling Solutions

End-to-end liquid cooling infrastructure delivered as a single integrated system. Apex engineers, manufactures, and tests every component so your racks arrive ready to connect, commission, and scale.

  • Single-source accountability for CDU, manifolds, RDHx, hoses, and controls
  • Factory acceptance testing and hydraulic balancing
  • Deployment support from design through commissioning
  • Designed for AI, HPC, and enterprise density targets
