Hybrid Air-Liquid Cooling Load Bank
Model No: GP-LB-HYB-228K-LC-V2-2510
// Overview
An intelligent, rack-optimized system designed for the commissioning and load testing of power supply systems, liquid-cooled cabinets, and Cooling Distribution Units (CDUs)
This integrated unit delivers a total capacity of 228kW, comprising a 180kW liquid-cooled unit and a 48kW air-cooled unit. To ensure high-precision testing, both units support continuous and stepped load adjustments with a 1kW minimum step. The equipment is engineered for durability and high-demand environments, utilizing 304 stainless steel pipelines, Class F insulation, and high-flow fans for reliable heat dissipation.
// FEATURES
Technological Breakthroughs
Dual Cooling System
By combining high-flow forced air cooling with a precision liquid-cooling circuit, the system provides the versatility required to simulate complex, modern thermal loads with high reliability.
Rack-Optimised Design
Engineered to fit standard rack dimensions, the equipment allows for seamless integration into existing cabinet infrastructures, making it ideal for on-site commissioning and testing, easy integration into data centres.
Intelligent Command and Control
Users can manage operations via local 10" touchscreen and remote automatic control.
Continuous Load Adjustments
The system supports both continuous and granular stepped adjustments with a minimum resolution of 1kW. This allows for exact simulation across the 180kW liquid-cooled and 48kW air-cooled sections:
- Liquid-Cooled: 1–180kW, minimum load step: 1kW
- Air-Cooled: 1–48kW, minimum load step: 1kW
Continuous Operation
Designed for long-duration stability, the equipment utilizes Class F insulation and pipelines made of 304 stainless steels to ensure consistent performance during extended load testing cycles.
Modular Expansion
Multiple units can be paralleled for higher capacity.
