ComRent provides electrical and thermal load testing services using load bank testing. They offer resistive, reactive, and capacitive load tests to validate the output of generators, UPS systems, batteries, and HVAC equipment. ComRent has the largest inventory of load bank equipment in North America, including medium voltage and DC load banks, and can test loads from 50MW down to less than 1kW. They provide load bank rentals, technical support, and commissioning services from 20 locations across North America.

1. What We Test
ComRent is your single source for electrical and thermal load
testing.LoadBankTestingisthemostflexibletestingmethodto
validate the operating condition and output of diesel and gas
turbine generators, UPS, batteries, and CRAC systems.
Look to us for:
• Resistive Load Tests – Mimics the operational load that
a power source will see in the actual application
• Reactive Load Tests – Provides a lagging load to
accurately simulate electric motor and pump function
• Capacitive Load Tests – Provides a leading power factor
to compensate for power factor correction on the utility
The bottom line: ComRent can test any load from 50MW
to less than 1kW at low or medium voltage.

Medium Voltage Load Banks
ComRent is the only load bank rental
company that has medium voltage load
banks, plus resistive and reactive testing
solutions, for the most accurate and
complete generator load bank testing.
We also test our load banks before we
deliver them to a customer’s site and test
them when they come back to our facility
to ensure reliability on the job.
Unrivaled service and support
