Rack-level CDU

Compact in-rack liquid cooling for single-rack and small-cluster deployments. Hot-swappable pumps, intelligent controls, and ultra-low energy consumption in a 4U form factor.

30 – 140 kW 4U In-Rack Hot-Swappable Pumps Modbus / TCP / UDP

Engineered for Reliability

Hot-Swappable Pumps

Redundant circulation pumps support online replacement without system shutdown, ensuring continuous cooling during maintenance.

Ultra-Low Energy Consumption

Designed for minimal power draw across all operating conditions, reducing total cooling energy cost over the system lifecycle.

Multi-Layer Protection

Condensation prevention, dual power input, leakage detection, and automatic shutdown on over-pressure or over-temperature alarm.

Intelligent Flow Control

Wide-range pressure drop adjustment with step-less flow control. Automatically adapts to varying server loads for stable coolant delivery across all operating conditions.

Open Protocol Integration

RS485 and RJ45 interfaces with Modbus, TCP, and UDP support. Compatible with BMS and third-party monitoring systems.

Sanitary-Grade Filtration

Hygienic stainless steel piping with fine filtration maintains coolant purity and protects cold plate integrity.
