Resistive Load Banks

RESISTIVE LOAD BANKS

Viking Power Systems range of resistive load banks are designed for both portable and permanently installed applications and can confidently withstand everyday use in a demanding industrial or rental environment.We can provide power proving resistive load banks to suit most applications including workshop or on-site load testing and permanently installed auto load shedding (ALS) units to prevent “wet stacking” of diesel generating sets when running on light loads. All Viking resistive load banks follow the same design philosophy of robust construction matched to a simple operator interface.

On most models this interface consists of a 7” colour touch screen with step size selection and load application easily controlled using large, easy to read soft keys and graphics. A dedicated plain English help screen is easily accessible should the operator require assistance or a fault occurs with the unit.

Our standard model range includes portable units in sizes from 8.4KW – 1000KW and fixed installation units starting from 20KW extending through to 2500KW and above. All Viking resistive load banks are manufactured with durable materials to ensure a long service life……

  • Powder coated electro-zinc plated steel bodies
  • IP65 low watts density 304 grade stainless steel load resistors
  • Extensive use of 304 grade stainless steel for grilles and hardware
  • Circuit breakers for each load group
  • Over temperature, air flow and fan failure protection
  • Quality electrical components from internationally certified manufacturers
  • Manufactured to AS/NZ-3000 electrical standards & CE compliant

PORTABLE RESISTIVE LOAD BANKS

Viking portable resistive load banksoffer a comprehensive range of load ratings from 8.4kW to 1000kW with features to suit most generating set or UPS testing requirements, either in the workshop or on-site. All models are manufactured using our standard IP65 stainless steel, low watts density resistors for a reliable service life. Units 50KW and above include our manual “Load-Logic” PLC controller with 7” colour touch screen interface. This provides manual control of load steps or the selection of an automatic
generating set load test sequence while providing comprehensive data feedback to the operator.Insulated resistor compartments ensure external temperatures are always maintained close to ambient for operator safety.

LOAD BANK RENTAL (Thailand)

Within Thailand and the nearby region we can also provide a range of portable resistive load banks for rental. All rental units are identical in design and manufacture to the load banks built for export customers and meet international electrical and OH&S standards.

  • Load banks available in ratings from 100kW – 1000kW, or combinations up to 2000kW
  • All load banks meet AS/NZ3000-2007 electrical standards and areCE compliant
  • Heavy duty roll frames with top lift is standard on all rental load banks
  • Simple colour touch screen PLC control interface (English Language)
  • Programmed maintenance and testing carried out on all rental equipment
  • Dry rental without operator or rental with experienced Viking staff if preferred
  • Suitable rated power cables also available for hire if required.

AUTO LOAD SHEDDING (ALS) LOAD BANKS

The Viking ALS “Load-Logic” range of load banks are designed to provide automatic single or multiple step loading of diesel or gas fuelled generating sets. The ALS units maintain sufficient base load on the generator to reduce or eliminate light load running. This is the primary cause of accelerated engine wear and “wet stacking” for prime power and standby generators and is common where the set is supplying a varying load.

The ALS Load bank’s customer programmable settings allow constant load sensing of the external load on the generating set and the automatic application or removal of load bank steps to maintain a pre-set load on the generator. Manual operation of load steps is also available for routing testing.

Standard or custom kilowatt ratings with a number of control options are available and can be tailored to customer requirements.

PERMANENTLY INSTALLED RESISTIVE LOAD BANKS

Viking’s full range of load banks can be supplied for permanent installation and we offer a range of options to assist with the installation process.

  • Suitable connection flanges for air discharge ducting when installed in plant rooms or other indoor locations.
  • Single or multiple remote “Load-Logic” touch screen controllers providing flexibility in the actual operating location for the load bank.
  • Digital power meteringproviding Modbus data feed for building management system monitoring.

CUSTOM DESIGNED LOAD BANKS FOR SPECIALISED APPLICATIONS

When harsh environments have an impact on the longevity of standard load bank, Viking can design and manufacture portable or fixed installation units with stainless steel (304 or 316) housings and major components. Custom resistive load banks can also be designed for specialized applications such as non-standard switching steps, high ambient temperatures and reduced operating sound levels. Please contact us with your requirements and we will endeavour to provide a suitable solution
