\n
\nOur liquid-cooled load banks are available in capacities ranging from 30 kW to 500 kW and can be scaled and combined to meet the requirements of your infrastructure. Compatible with both pure water and glycol, they ensure temperature control accuracy of \u00b10.5\u00b0C for reliable and reproducible test results.
\n
\nTest before installation: no surprises during commissioning<\/strong>
\n
\nValidating your cooling infrastructure before installing equipment is a best practice that many data centers adopt too late. Our liquid cooling load banks simulate the actual thermal load of your racks to test CDU units, chillers, and cooling loops under conditions that mirror real-world operation. Leaks, pressure drops, thermal inefficiencies\u2014everything is identified early on, when addressing issues is still cost-effective.

\nLiquid-cooled load banks<\/strong>
\n <\/p>\nThe energy requirements of data centers are growing; newNew servers incorporate increasingly powerful CPUs and graphics cards, reaching power densities so high that air cooling is no longer sufficient to properly cool the racks. That is why, today, nearly 40\u202f% of data centers have adopted liquid cooling technology in one form or another. Our liquid-cooled load banks enable you to meet these new requirements for testing and validating data center infrastructures under realistic conditions that accurately reflect actual operations.<\/p>\n

<\/a><\/span><\/div>Resistive load banks<\/h3><\/div>Resistive load bank: How does it work?<\/strong>
\n
\nA resistive load bank converts electrical energy into heat via resistors, thereby simulating a purely active load. This is the industry-standard solution for testing equipment with a predominantly resistive load: generators, UPS systems, and backup power supplies. Easier to implement than a resistive-reactive bench, it meets the vast majority of testing needs in industrial and commercial settings.
\n
\nWhat type of test is this for?<\/strong>
\n
\nDelta-Resistel resistive load banks are used at three key stages: during commissioning to verify the actual performance of the equipment; during routine maintenance to ensure that generators and UPS systems can handle their rated load; and at the factory for acceptance testing prior to delivery.
\n
\nReliable solutions for electrical testing and maintenance.<\/strong>
\n <\/p>\nDelta-Resistel resistive load banks<\/strong> are designed to ensure the performance, reliability, and safety of your electrical systems. Used to test generators<\/strong>, uninterruptible power supplies (UPS), and power distribution systems, our equipment simulates real-world loads to verify the proper operation of your systems under controlled conditions. <\/p>\nThanks to their robust design and high-quality components, our load banks offer optimal heat dissipation<\/strong>, high load accuracy, and ease of use, making them suitable for maintenance operations as well as factory or on-site testing.<\/p>\nDelta-Resistel offers a comprehensive range of solutions, from portable load banks<\/strong> to high-power systems.<\/p>\nOptimized to meet the demands of the industrial, commercial, and energy sectors, our resistive load banks are the ideal solution for testing, monitoring, and safeguarding your electrical equipment<\/strong> while ensuring compliance with current standards.<\/p>\n3 key features of the line:<\/p>\n

<\/a><\/span><\/div>Resistive\/Reactive Container Load Banks<\/h3><\/div>Resistive, reactive: what’s the difference?<\/strong>
\nA resistive load bank simulates a purely active load and covers most common tests. However, in reality, most industrial electrical systems combine active and inductive loads: motors, transformers, and variable-speed drives. A resistive test bench alone cannot reproduce these conditions. The resistive-reactive test bench adds the inductive component to test under variable power factors, as closely as possible to the actual operating conditions the equipment will experience. <\/p>\nThe container format: test it anywhere, even under challenging conditions<\/strong>
\nOur resistive-reactive test benches are available in containerized formats for projects that require them. Self-contained and portable, they can be installed directly on-site without the need for dedicated infrastructure, making them ideal for construction sites, remote locations, or temporary installations. The container protects the equipment from outdoor conditions and allows for quick deployment, no matter where your installation is located. <\/p>\nA clear picture of<\/strong> your facilities’ performance<\/strong>
\nDelta-Resistel resistive\/reactive load banks combine resistive and reactive loads to accurately replicate the actual operating conditions of electrical installations. They enable testing of equipment (generators, inverters, data centers) under varying power factors by simulating the stresses associated with inductive loads.
\nDesigned for demanding environments, our test benches guarantee reliable, accurate, and representative testing, ensuring the performance, stability, and compliance of your critical installations.
