200kw 380v Liquid Cooling Load Bank

The 200kW 380V Liquid Cooled Load Bank from RST Electric represents a paradigm shift in high-power testing technology. Housed in a standard 42U rack enclosure (W600×D1400×H1800mm), this 200kW 380V Liquid Cooling Load Bank eliminates the need for massive air handlers or facility exhaust systems by transferring heat directly to a facility's existing liquid cooling infrastructure. The system features a 304 stainless steel coolant circuit with DN32 inlet/outlet connections, capable of handling flow rates up to 200L/min (12m³/h) at design pressures of 0.4MPa.

Precision temperature sensors monitor inlet/outlet coolant temperatures, maintaining a stable thermal load with ≤15°C temperature rise at full power and ≤5psi pressure drop. The resistive load bank itself offers 5kW step resolution with ±2% loading accuracy, enabling granular simulation of real-world IT loads. Control options include local HMI touchscreen, remote PC software, RS485/Modbus RTU, and full data logging capabilities.

As a leading 200kW Liquid Cooling Load Bank manufacturer in China, RST Electric combines over 15 years of power resistor expertise with cutting-edge liquid cooling technology to deliver solutions that meet the demanding requirements of next-generation data centers and high-performance computing facilities.

Project Cases

1. Project Background

This hyperscale AI data center in Johor, Malaysia adopts full cabinet CDU liquid cooling circulation system for GPU server cluster. In project acceptance phase, the core requirement is to authentically verify actual cooling capacity of CDU liquid circulation loop, simulate real heat dissipation load generated by in-cabinet high-density servers.

Traditional air-cooled load cannot connect with site water circulation pipeline, unable to feed constant heat load into CDU loop for long-run cooling performance inspection; bulky air cooling equipment cannot be installed inside standard 19-inch rack to restore real cabinet heat layout.

Affected by Malaysia tropical high-temperature ambient all year round, clients need rack-type liquid access load bank matching onsite coolant medium to complete continuous thermal load inspection of CDU system and synchronous UPS/standby generator full-load testing. RST Electric supplied batch 200kW 380V closed liquid-cooled rack load banks to realize accurate CDU cooling capability certification complying with local TNB power acceptance standards.
