Load banks for rental or sale

Hillstone Products, a UK load bank company, have for over 20 years designed, manufactured and rented AC & DC load banks to customers across the world.

The manufacture factory is based in Manchester, England which supports overseas sales offices in Dubai via Hillstone Middle East Trading LLC and other partners in Europe, Middle East and the Far East to give a high quality engineering solution to your load testing requirements.

The available range of 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.

In addition to load bank supply we can also offer full Datacenter Load Testing and Commissioning, to provide an independent verification service as part of Integrated System Testing and Tier Certifications.

Hillstone operates its load bank rentals and manufacture to the accredited ISO90001:2008 Quality Assurance System to ensure the highest standards are continuously maintained and delivered to the customer.

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.

The latest addition to this range is a low cost solution for auto load shedding and control load banks, used to prevent wet stacking of gensets

AC load banks 500KW to 1200KW Available power ratings from the HAC range include:

10KW, 30KW, 100KW, 200KW, 250KW, 333KW, 500KW, 600KW, 800KW, 1000KW, 1200KW.

Operating voltages: 120V/ 208V, 220V/380V 230V/400V, 240V/415V 277V/480V, at 50Hz or 60 Hz

Loadbank hand held controller The Hillstone iHHC2 hand held controller gives the user a robust and very user friendly interface to the load bank.

The iHHC2 features include impact load testing and parallel control of multiple load banks with an LCD display allowing 270 degree viewing angle even in direct sunlight.

Application Note 1

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.


Application Note 2

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.
