Built for High-Density Cooling

Wide Capacity Range

Two product series covering 300 kW to 1,700 kW. Match cooling capacity to any rack density — from standard enterprise workloads to GPU-intensive AI training clusters.

Redundant Architecture

Key components including pumps and valves are fully redundant. Dual power input and automatic switchover keep the system running without shutdown during maintenance or power events.

Intelligent Flow Control

Multi-mode pressure differential control with step-less flow adjustment. Supports cold standby, hot standby, independent operation, and group control across multiple CDUs.

Global Certification

CFUS series (600–1,700 kW) complies with both CE and UL standards, enabling deployment in North America, Europe, and regulated international markets.

Modular & Serviceable

Modular cabinet design with front and rear access for maintenance. Supports automatic online coolant refilling and configurable pipe direction, filter class, and communication options.

Open Protocol Integration

RS485 and RJ45 interfaces with Modbus, TCP, and UDP protocol support. Compatible with BMS, DCIM, and third-party monitoring platforms for centralized facility management.
