Load banks for rental or sale

Hillstone Products is a UK family based business which for the past 20 years have designed, manufactured and rented AC & DC load banks to customers across the world.

We operate with sale partners in Europe, Middle East and the Far East to give a high quality engineering solution to your load testing requirements.

Our loadbanks are used for testing battery systems, UPS systems, fuel cells, HVAC systems and generators in industries such as Oil & Gas, Power Generation,
Petro-Chem, Telecoms, Data Centers.

Full technical support for the range of load banks are available within this web site and our sales offices are available to assist with any requirement that you may have.

100KW load banks AC load banks are used for power testing single phase and 3 phase generators and UPS systems.

The range includes for indoor and outdoor testing requirements, with designs covering from small compact light weight portable units to high powered trailer mounted loadbanks.

Available power ratings from the HAC range include:

10KW, 30KW, 100KW, 200KW, 250KW, 333KW, 500KW, 600KW, 800KW, 1000KW, 1200KW.
Operating voltages: 380V to 690V, 50/60 hz

Loadbank hand held controller The Hillstone iHHC hand held controller gives the user a robust and very user friendly interface to the load bank.

The iHHC features include impact load testing and parallel control of multiple load banks from our CANbus communication technology.

AC LoadView Software LoadView-AC provides datalogging the performance of your Genset or UPS on Windows XP or Windows 7 operating systems.

LoadView-AC provides powerfull user interactive graphical displays and with ease to issue reports of the completed test.

HBN load bank DC load banks offer solutions to meet the budget and technical requirements of all battery discharge testing.

HBN range for economy discharge testing

Hillstone operates its load bank rentals and manufacture within the accredited ISO90001:2000 Quality Assurance System, to ensure the highest standards are continuously maintained.


Regular load bank testing of generators provides an essential health check service to prevent diesel engine failure due to wet stacking. Wet stacking occurs due to under loading of the genset which results in wet un-burned fuel building up in the engine. This fuel build up will over time line the combustion chamber cylinders and cause a reduction of the engines rating and efficiency which will ultimately cause premature failure of the generator.Running the generator on load of 50% - 100% of the genset rating will allow the engine to reach the recommend operating temperature, which will burn off the choke deposits. Hillstone and our partners can provide preventive maintenance programs.


Discharge testing is the approved method to determine the capacity of Lead acid and (Nickel Cadmium) Ni Cad/Ni Cd batteries, as recommended by all battery manufacturers such as Enersys, Exide, C&D Technologies, Hawker, Yuasa, Exide, Hoppecke, Saft, Varta, and in accordance to BS6290 part 4 / IEC TR 62060.
