What Is A Load Bank? (Dummy Load) Load Banks are devices designed to provide electrical loads for testing power sources such as Generators and Uninterruptible Power Supplies (UPS). Normal/Emergency Loads Load Bank
Why Are Load Banks Necessary? Maintain reliability of the Emergency Power System by testing of the engine generator (s) under load.
Testing With A Load Bank Will Help Insure
Your Engine Generator Will Deliver The Power It Is Required To Do!
Recommended / Required Testing Of Engine Generators Frequency Duration Capacity Monthly 30 – 40 Minutes 50% to 60% of Engine Generator Rating Annually 2 Hours 100% of Engine Generator Rating (Resistance/Reactance)
When it is unfeasible to apply actual load, it is recommended to use a Load Bank
NFPA Required Testing Of Engine Generators Hospital And Health Care Frequency Duration Capacity Monthly 30 Minutes 50% of Nameplate Rating Of Engine Generator Annually 30 Minutes 100% of Nameplate Rating Of Engine Generator
Please Realize . . . Your Generator Is Only As Good As Your Last Full Load Test! AC Kilowatts
Full Load Testing Assures proper KW, Voltage and Frequency AC Kilowatts
Full Load Testing Confirms the Reliability ofcomponents such asFuel & Cooling Systems
Another important reason to operate your standby generator under load… Diesel…The Preferred Fuel For Standby • A Diesel Engine Generator Should Always Have At Least A 50 – 60% Load Connected While Running - - - Or “Wet Stacking” Could Occur - - -
Unburned Fuel Causes Carbon Build Up Excessive Oil Consumption Reduced Horsepower….Reduced Efficiency Premature Failure “Wet Stacking”
Wet Stacking Is Most Common . . . Applications With Varying Loads Engine Generators Sized For Pump Starting Currents And All Pumps Running At One Time
Wet Stacking Is Most Common . . . • Gen-Set Was Oversized For Future Growth Or Redundancy Emergency Bus N + 1 Engine Generators
Types Of Load Banks Radiator/Duct Mounted • Portable • Permanent/Free Standing
Portable Load Bank Service & Rental Applications From 70KW To 500KW • Mounted On Casters • Fit Through Doorways & Elevators • Lightweight
Portable Load Bank Trailer Mounted From 1000KW To 2100KW • Heavy Duty Dual Axle Trailers • Low Profile Horizontal Discharge (Up To 1000KW) • Vertical Discharge (1400KW TO 2100KW) • Optional Cable Reels

Portable Load Banks Trailer Mounted . . . To 2100KW
Portable Load Banks Facility Normal/Emergency Loads Tap Box Synchronizing Gear Arranged For Spare Portable Engine Generator Portable Engine Generator Portable Load Bank - Or - Portable Load Bank
Radiator Mounted Load Banks Dedicated Engine Generator Sets • Typically 50-60% Of The Generator Rating
Radiator Mounted Load Banks From 15KW . . .
Radiator Mounted Load Banks . . . To 1000KW
Permanently Mounted Free-Standing Load Banks Static Pressure May Be Too High For Radiator Mount • Multiple Generator / Use Applications
Permanently Mounted Free-Standing Load Banks Multiple Engine Generator Sets That Are Paralleled
Permanently Mounted Free-Standing Load Banks Facility Normal/Emergency Load Bank Loads Multiple Engine Generator Sets That Are Paralleled
Permanently Mounted Free-Standing Load Banks Multiple Use Engine Generator Sets and UPS
Permanently Mounted Free-Standing Load Banks Facility Normal/Emergency Load Loads Bank K For UPS Test Multiple Use Engine Generator Sets / UPS
Permanently Mounted Free-Standing Load Banks From 50 to 2000 KW . . .
Traditionally, Permanently Mounted Load Banks Discharge Horizontally
Horizontal Discharge is the most economical design to provide the best protection against all environments
When Installing a Permanently Mounted Free-Standing Load Bank Consider. . . Free Air Space for Cooling Air & Hot Exhaust • Location Of Installation 1KW-hour = 3,413 BTU 1,000 KW – hour = 3.4 Million BTU
Permanently Mounted Free-Standing Load Banks . . .To 2000KW
For Applications 700-2100 KW • Heat Dissipates Vertically • Less Real Estate Required
