Customized load banks

Our load banks are custom-designed and -manufactured

We offer equipment and customization options:

Our load banks are controlled by an intelligent control system

You can thus control your load banks locally or remotely , with essential or more advanced features. We thus offer STANDARD mode or PREMIUM mode

Test, ballast and maintain your electrical equipment!

It is essential to regularly test energy production systems such as generators, batteries, inverters …
This in order to check their proper functioning and maintain them to prevent fouling or early damage. In short, for reasons of:

  • security
  • maintenance
  • conformity
  • anticipating risks

Why use a load bank?

Manufacturing test

A load bank, associated with a generator , allow the unit to be charged in order to prevent diesel engines from clogging and their premature wear, especially at low power.

Generator testing and maintenance

According to the standards in force, the generators and other motors generating electricity must be tested monthly. These generator tests are carried out with load banks. They make it possible to determine:

  • operating capacities
  • start-up responsiveness

Maintenance of accumulator batteries

The load bank allows discharge or unload the battery avoiding premature wear. It is mainly used in electrical laboratories, on test platforms, in data centers and in telecommunications.

Test bank

The load bank is used for the purpose of testing and adjusting protection and breaking devices.

Load banks suitable for all applications

This expertise makes it possible to design equipment adapted to all constraints:

Direct current and alternating current load banks: test and respect the load cycle

Depending on the electrical equipment, the current distributed can be alternating or direct.
The direct current is very present in sectors of activity with specific high voltage constraints and in on-board systems, via batteries .

A generator is a thermal engine fitted with an alternator which allows thegeneration of alternating current . Coupling to a load bank offers the possibility of testing it, validating its power, removing clogging regularly, or ballasting it, depending on its use.

Load bank for direct current equipment: batteries

The batteries therefore have direct current.

Depending on the different technologies, it is necessary to discharge the electric batteries regularly to allow a full charge cycle .

For all types of batteries , in particular lithium-Ion, it is imperative to unload them before transporting equipment or when moving for example.

Battery site

Indeed, it is then essential to discharge the battery with a discharge bank beforehand, so as to avoid electrocution by direct contact, or the generation of sparks, etc. For any type of battery, particularly lithium-ion, it is essential to unload it before transport, so as to avoid electrocution or the generation of sparks, etc.

Load bank for alternating current equipment: generator set

A Generator , is a thermal engine fitted with an alternator, which generatesalternating current . The coupling to a load bank then offers the possibility of:

  • testing it and validating the power of the generator set,
  • cleaning it regularly,
  • or to ballast it, depending on its use.

The proper functioning of a generator set and the maintenance of its performance over time depends mainly on:

  • assiduity of tests
  • tests carried out regularly.

Reactive and resistive load banks: correct the apparent power supplied by the generators and reproduce the real demands on critical power systems

Reactive load bank

Reactive power is required in many systems, especially those equipped with a winding. It can be supplied by capacitor banks. The load bank corrects this reactive power or corrects the cosine Phi.

We propose two types of reactive load .

These types of load banks are used to:

  • decrease or increase the value of the phase shift between the network voltage and the current absorbed by the installation
  • test the alternators under full load.

Nuclear plant

Resistive load bank

Via resistive components, the load bank:

  • applies an electric charge to power source
  • dissipates energy which results in the form of thermal heat.

The integrated motorized fans will play their role of cooling these resistive elements.
The resistive load banks are thus the best way to reproduce and verify actual requests on critical power systems.

The resistive load bank is also used for:

  • generator set test phases at 100% of the nominal value in kW on the nameplate.
  • complete charge of generator cooling systems, fuel and exhaust systems.

Using a load bank: a return on investment

ROI and business benefits of a load bank:

  • Increase the lifespan of installations and therefore better profitability
  • Reduce the risk of breakdowns and costly repairs
  • Reduce fuel consumption and limit polluting emissions
  • To avoid immobilization forced from your generators
  • Meet regulatory requirements for safety generating sets, in terms of fire and panic risks (Article EL18: ERP – Decree of June 25, 1980 and Article GH43: IGH – Decree of December 30, 2011)

Applications in demanding environments

Electrical installations, in France and internationally, require precision that meets the challenges of the most critical markets.
