Founded in 1997, ComRent provides load banks for the testing and commissioning of primary and backup electrical generating and mechanical systems. Headquartered in the Washington, D.C. metro area, we’ve grown from a single location to the largest provider of load bank rentals in North America.

Load bank testing is the most flexible method to validate the condition and output of generators, UPS, batteries, and CRAC systems. With unmatched inventories in more locations than any other vendor, ComRent can be your single source for all electrical and thermal load bank testing requirements

We are the only company offering medium voltage load banks that do not require transformers. We can provide load banks from 1kw to 50 MW at low or medium voltage, AC or DC. This means you can run a faster, more accurate test while benefiting from faster set up and tear down.

Look to ComRent for:

• Resistive Load Banks – to mimic the operational load that a power source will see in actual use.
• Reactive Load Banks – to provide a lagging load to accurately simulate electric motor start up and pump function.
• Capacitive Load Banks – to deliver a leading power factor to compensate for power factor correction on the utility.

With 18 strategic locations and North America’s largest inventory – over 2,500 pieces of equipment and 90 miles of cable – we can meet a wide variety of electrical and thermal load testing requirements, regardless of industry and testing objectives. We built the first and only medium voltage load bank in the rental market for testing large, multi- generator plants. We also developed the first rack mount load bank with variable load, CFM and wireless remote control.

And with more than 30,000 load tests performed and a 99.99% on site success rate, there’s isn't a more experienced company in the business. We test our load banks before and after delivery to ensure reliability on the job. That’s because load testing is our only business. As a result, you can rest assured that our load banks will consistently deliver accurate results nationwide -- helping complete your test on time and on budget every time.
