Middle East Power editorial Feb 2011

The following article is a copy of the editorial in the February addition of Middle East Power.  Middle East Power is the official magazine for the Dubai based Middle East Electricity Show held on the 8th to the 10th February 2011.

This press feature covers a recent load bank rental project for the new Green Line of the Dubai Metro which used both hire AC & DC load banks.


The Dubai Metro loads up with Hillstone
In a major contract Hillstone Products Ltd recently provided loadbanks for 
the autonomous testing of the UPS systems installed by the Dubai Metro, a 
driverless, fully-automated Metro network in the United Arab Emirates 
city of Dubai in the UAE. WIP has the story.

When the Dubai Metro needed to find load banks to commission standby UPS systems on the Dubai Metro Green Line, it was fortunate that a UAE hire fleet from Hillstone Products had just the range of AC & DC load banks to fit project requirements.

The Dubai Metro, a driverless, fully- automated Metro network in the United Arab Emirates city of Dubai in the UAE, has already carried approximately 20 million passengers since it opened in 2009.
Hillstone reports that 200kW and 300kW AC units along with 120V DC load banks were supplied for autonomy load testing and battery capacity testing by the Metro.

Paul Smethurst, MD of Hillstone, told MEP: “Since 2008 Hillstone have successfully operated a specialised Load Bank Rental Service from Dubai covering the whole Middle East region.”
Hillstone’s Load Bank Fleet contains an extensive range of both AC and DC units. The DC load banks are said to be very portable and allow for ease of movement to the battery or UPS room by one man.  The AC load banks are designed with a small footprint and can deliver high power ratings with the use of the intelligent parallel hand held controller.

A cornerstone of the successful rental service is the technical support given by the UK engineering department, says the company. Every enquiry is fully supported to ensure the UAE sales team can provide the highest engineering standard and solution to the customer.
Part of the technical discussions for DC load banks requirements often starts with the need to established the type, size and capacity of the battery to allow selection of a suitable load bank, says Paul.
“Our customers get the reassurance from our extensive experience of UK engineering standards to ensure the load bank package suits the commissioning needs” Paul reports.

“Our DC load banks are used for commissioning testing for both Ni-Cad and Lead Acid batteries used on telecom and UPS standby systems. With ratings available from 12V to 600V and allowing discharge testing from 50A to over 4000A, we can satisfy most requirements across the Middle East,” says Paul.
All the specialist equipment has been designed and manufactured by Hillstone in the UK and regular additions to the fleet are introduced.

The Middle East fleet includes AC load banks of both single-phase and 3-phase designs with portable equipment rated from 14KW 240V single phase. Larger 3 - phase designs include 100KW, 200KW, 300KW, 500KW and 650KW load banks, with total power availability of over 3000KW when the units are linked together.

One recent project involved the supply of 650KW load banks to Qatar Gas for the Dubai-based oil rig manufacturer J Ray McDermott. A load bank was required for the commissioning & testing of the platform’s electrical power system during production in Dubai and also during the rig transfer to Qatar.

Hillstone has expansion plans for 2011 which include the opening of a new rental depot in the Kingdom of Saudi Arabia. “This is a very exciting opportunity with the introduction of a depot inside the Kingdom allowing for an enhanced service to customers and an opportunity to overcome the importing and re export costs presently experienced,” Paul concludes.

Generator testing using AC load banks


Regular maintenance
Wet stacking occurs predominantly with under loaded gen-sets that are used in prime power applications. By using a load bank, as part of any regular maintenance routine, will provide the generators an essential health check and prevent diesel engine failure due to wet stacking. 


Wet stacking
Wet stacking occurs due to the lightly loading ( at levels of less than 35% for a prolong time period ) of a genset.   The consequence of low loading results in wet un-burned fuel deposits building up in the engine cylinders. This fuel residue over time will line the combustion chamber cylinders and cause a reduction of the engines performance rating and efficiency which will ultimately cause premature failure of the generator. 



As part of the regular maintenance it is recommended that the genset is loaded in incremental steps with due consideration of the age and service history of the genset is given prior to  loading at 100%


Running the generator on loads above 35% of the genset rating will allow the engine to reach the recommend operating temperature, which will burn off the choke deposits. 


Load bank generator service
Hillstone Products can provide the complete genset load banking package.  Our load bank team(s) operate across the whole of the UK and the supplied service frequently involves:


  •                Off loading of the load bank
  •                Positioning of the load bank with safety barriers as required
  •                Laying cables without causing obstruction
  •               Operating load bank  
  •                Removal of equipment from site
We are happy to work along side customer's service teams or on behalf of customers as required.


The available range of load banks allows for testing of gensets up-to 2000KVA.
Our sales team are available to discuss your Genset testing requirements:

19" rack data center HVAC load banks

Within a server room installation and commissioning of HVAC, the use of dedicated 19" rack load banks are used as server simulators to provide heat exchange testing conditions.  This allows for verification of HVAC design and performance of cold & hot aisles.




The power consumption of server rooms typically can range from 90KW to more than 2000KW.  The use of load banks for HVAC testing by virtue that they are connected into the power infrastructure therefore allow verification of  the electrical wiring & balance of the PDU and also as part of black start testing of the standby power UPS & generator systems. 


Fitting the load banks into the racks prove to potential customers the electrical supply is ready to have the very expensive servers installed and switched on.


The typical ratings of single phase 19" load banks include 2KW, 3KW, 4KW and 6KW, allowing for connection to 16A - C19 sockets or 32A - IEC309 / BS4343 commando plugs.


Alternative solutions include the use of 24KW aisle load banks that provide 6 x 4KW load channels that are directly connected via 32A - IEC309 / BS4343 commando plugs to the under floor or ceiling mounted supply points within the data rooms.



Once the load banks are fitted it is also important to install blanking plates to seal off the racks to create  realistic thermal conditions.


Hillstone provides a complete service of load bank rental supply and installation.  We work closely with the customer to ensure the loads are installed balanced across the PDU and connected under the floor or up to ceiling power points.
