Resistive/reactive load bank rentals

Combined resistive reactive load banks for reliable testing from 240 kW to 6.25 MVA

We provide dependable, custom-engineered resistive/reactive load banks to help you test confidently, improve reliability, and maintain performance

Resistive/reactive load banks enable you to test equipment by replicating a lagging power factor. This is vital for complete engine and alternator tests, which purely resistive load banks can’t provide, since they only test at a unity power factor.

At Aggreko, we provide resistive/reactive load bank rentals across voltages from 380 V to 690 V, delivering multiple 1 kVA load steps so you can:

Fully test equipment with load banks offering a typical 0.8 power factor
Benchmark equipment performance against manufacturer expectations
Meet legal requirements for load testing during commissioning
Identify potential problems and maintenance issues sooner

Resistive load banks

Load-test your equipment with pure resistive loads. Our resistive load banks support up to 5MW in a single unit.

Supporting your resistive-reactive load bank testing applications

Meet legal requirements for load testing and reporting. We can provide a resistive/reactive load bank rental designed around your required load profiles and durations, alongside sophisticated handheld controls and integrated data capture.
Test your backup energy equipment by simulating loads to measure performance and efficiency. With our resistive/reactive load banks, you can test equipment at full load and resolve issues before they become costly problems or lead to downtime.
Resolve maintenance issues including degrading insulation before they escalate into disasters. With regular load testing, you can spot problems sooner – and fix them faster.
Avoid wet-stacking and carbon buildup in generators by using a load bank to determine capabilities and output. A load bank rental can also be used to provide load that clears out known carbon buildup in an engine.
Simulate performance at peak demand safely and accurately with a resistive/reactive load bank. Its modular design means you can run multiple load banks in parallel for near-limitless scalability.
Meet schedules and performance expectations by thoroughly testing your equipment or resistive and reactive generator energy performance earlier in the process.

Frequently asked questions

Resistive and reactive load banks are devices used to test the performance and reliability of energy sources like generators and UPS systems under real-world load conditions.

They’re called ‘resistive and reactive load banks’ because they contain both resistors and inductors, which means they can be used to test equipment under a wider range of operational conditions.

The key difference lies in the type of load being simulated:

Resistive testing evaluates the ability of a system to manage real-world energy loads, typically representing simple electrical loads that convert energy into heat.
Reactive testing goes a step further by assessing how well a system handles inductive (lagging) or capacitive (leading) loads, such as those created by motors or transformers. Reactive load testing is critical for industrial environments where machinery creates complex energy demands.

Combining both types of testing ensures the generator or UPS can handle a range of load types effectively.

Testing both resistive and reactive loads provides a comprehensive assessment of an energy system’s capabilities.

Resistive load testing shows how the system handles standard, real-world electrical demands.wider testing.
Reactive load testing adds another layer by simulating the effects of inductive or capacitive components (such as electric motors), which are commonly found in industrial operations.

This combination ensures that the energy system can perform reliably under varied and demanding conditions, avoiding the risk of energy failure when exposed to actual operational loads.

Aggreko’s resistive and reactive load banks offer several benefits, including:

Accurate and reliable testing: Our load banks provide precise simulations of both simple and complex power loads, ensuring a thorough test of your energy systems and generators.
Scalability: Our load banks are available in a wide range of capacities, making them suitable for both small and large energy systems.
Flexible rental options: Aggreko offers both short-term and long-term rental options, so you can test your equipment as required without significant investment.
Expert technical support: Our team can assist with setup, operation, and interpretation of results, ensuring a seamless load testing process.

By using Aggreko’s load banks, you can identify weaknesses in your energy system before they lead to costly operational failures.

Load banks are an essential tool in preventative maintenance for your energy systems. By simulating real-world conditions, resistive and reactive load banks allow you to:

Identify potential failures: Testing under load conditions can reveal issues like overheating, poor fuel efficiency, or inadequate voltage regulation.
Ensure proper system calibration: Load banks help verify that your system is correctly configured and ready to perform at its rated capacity.
Extend equipment lifespan: Regular testing with load banks helps prevent damage from unexpected loads, ensuring that your equipment remains in good condition over time.

Preventative maintenance through load testing reduces the likelihood of system failures and increases the overall reliability of your equipment.

Yes, Aggreko’s load banks are versatile and can be used for a variety of systems, including:

Generators
Uninterruptible power supplies (UPS)
Transformers
Backup energy solutions

Resistive load banks apply a purely resistive load, converting electrical energy into heat to simulate real-world usage. They’re ideal for testing generators, UPS systems, and transformers under standard operating conditions.

Resistive/reactive (or inductive) load banks add an inductive element, which simulates a lagging power factor—common in industrial settings with motors and transformers. These are essential for testing how systems perform under both real and reactive load conditions.
