Deyang Rata Technology Co., Ltd. has introduced the SIRL-6000L, a mobile resistive-inductive integrated load bank with an apparent power rating of 7,500 kVA and an active power rating of 6,000 kW. The system is designed for high-capacity electrical testing applications involving gas turbine generator sets, marine diesel generator sets, land-based diesel generator sets, and uninterruptible power supply (UPS) systems.

Deyang Rata Technology Co., Ltd. has announced the launch of the Rata 4MW RLC Combined Load Bank, a new power testing solution designed to support comprehensive testing, commissioning, and performance verification of generators, energy storage systems, and industrial power equipment. Introduced in July 2026 in Deyang, China, the containerized load bank integrates resistive, inductive, and capacitive load capabilities into a single platform for a wide range of power system applications.

Commissioning is essential to ensuring performance and reliability and is an important phase before the start of operation of a power facility. To ensure these designs are met, generators, uninterruptible power supplies (UPSs), transformers, switchgear, and battery energy storage systems (BESSs) all need to be tested under realistic load conditions.

Liquid-cooled load banks are a critical component in the testing of generators, UPS systems, battery energy storage systems, and other critical power equipment. With the increasing power requirements of data centers, industrial plants, and renewable energy systems, more efficient load banks offer lower operating costs, more accurate testing results, and longer equipment lifetimes.

Liquid-cooled load banks are widely used to test generators, UPS systems, battery energy storage systems, and other critical power equipment. They can dissipate heat effectively, making them well-suited for continuous, high-capacity testing applications such as renewable energy generation, industrial facilities, and data centers.

Liquid cooled load banks are used to test high-power systems while transferring generated heat into a liquid cooling circuit. They are commonly used in data centers, AI infrastructure, industrial facilities, and other applications where traditional air-based testing cannot handle the thermal demand. When the system works correctly, it can provide stable electrical loading and realistic heat simulation.

Liquid cooled load banks are becoming increasingly important for testing high-density power and cooling systems. As data centers, GPU facilities, and other high-performance environments generate more heat, the cooling loop must move coolant at the right rate to remove that heat effectively. A flow that is too low can lead to rising temperatures. Excessive flow may create unnecessary pressure losses and place extra demand on pumps.

Cloud computing, artificial intelligence, financial services, and mission-critical applications, all of which require a continuous power supply, can be accommodated by today's data centers. Prior to these facilities going into operation, all the electrical equipment must be load-tested to ensure it will function reliably under actual operating conditions.

The rapid growth of artificial intelligence is changing the design, testing, and commissioning of data centers. Modern GPU servers can consume large amounts of power while producing concentrated heat in a relatively small rack footprint. This is difficult to test for facility operators in traditional systems. Traditional air-based load testing may confirm electrical performance. However, it may not accurately represent the thermal conditions created by liquid-cooled GPU infrastructure.

The metric known as Power Usage Effectiveness (PUE) has emerged as one of the most significant measures for measuring the performance of a typical data center today. Operators are increasingly challenged to cut power usage and still keep their infrastructure performing as required with the rise of new workloads, scaling of hyperscale infrastructure, and the deployment of high-density servers.

As power densities continue to rise across all types of critical installations, power system testing is becoming increasingly challenging. The selection of the optimal load bank cooling technology is directly related to the efficiency, installation flexibility, cost, and long-term reliability of the cooling technology.

Deyang Rata Technology Co., Ltd., as a resistive inductive load bank manufacturer and a developer of power testing solutions, has announced the launch of the SIRL-250L Series 250kVA AC Resistive-Inductive Load Bank, expanding its portfolio of testing equipment for industries requiring precise electrical performance verification. The introduction reflects growing demand for advanced testing technologies as utilities, industrial facilities, data centers, and energy storage projects place greater emphasis on power system reliability and operational readiness.
