The following IST datacenter blog is issued from the published article in the November 2012 addition of  World in Power magazine.

Prior to the Integrated System Testing phase of the comissioning of a datacentre, the suppliers of individual M+E equipment, such as gen-sets, UPS, HVAC Systems, may well have already completed specific commissioning on their own systems, explains Hillstone’s Paul Smethurst.

Integrated System Testing ( IST ) has become an essential part of the commissioning of datacentres. This final testing procedure brings together the operational running of the individual mechanical and electrical systems to prove the data hall will function to is original design and operating specification.

Prior to the IST, the suppliers of individual M+E equipment, such as gensets, UPS, and HVAC may well have already completed specific commissioning on their own systems.

Hillstone’s managing director, Paul Smethurst explains: “Our range of 19” rack-mounted loadbanks have been supplied to test both HVAC and the electrical power infrastructure. When the rack-mounted loadbanks are fitted into our 20KW Mini-Towers, data halls can be commissioned and even sold to clients prior to ‘fitting out’ of the racks.”

Server simulators or 19” rack-mounted loadbanks form an essential part of any IST procedure. These loadbanks are used to provide an evenly distributed load in the data hall. This live simulation is used to fully test the electrical infrastructure and the installed Heat - Ventilation - Air Conditioning system.

Simulating a mains failure is also recommended as part of the IST procedure.
This will verify the switching sequence performance of the electrical backup system to ensure the power is automatically transferred to UPS and generators.
It also ensures the power can be restored without interruption or failure.

Paul Smethurst explains: “Hillstone’s range includes specifically-designed server simulation rack-mounted loadbanks plus high- powered loadbanks for UPS, generator and battery testing.”

He said: “These loadbanks are also available in the UAE as part of our Middle East rental service. We have supplied server simulators to perform IST procedures on many occasions and have found both major and minor problems in data halls.”

Datacentre problems identified during the use of Hillstone loadbanks over the past four years include:

* Failure of CRAC units resulting in flooding in the data hall.
* Electrical wiring mistakes from PDU to racks.
* Electrical riser overheating due to bad cable connections.
* System design errors.
* HVAC installation faults resulting in pipe failures - a pipe in a hot area actually melted.
* UPS failures.
* Highlighting of inadequate power avail- ability to the datacentre.

Paul continues: “ This is the only time we see people happy when things are going wrong. Our equipment detects these kinds of key problems well before the client has to discover them.”

Hillstone’s business is doing well both in the UK and abroad.  

To date, the company has supported IST projects for customers such as:
  • Media City - Manchester UK (the new home of the BBC Television Centre),
  • Media City - Manchester
  • Sky News Arabia in Abu Dhabi,
  • Telecity London UK (one of the largest co-location providers in Europe),
  • Lynx Telecom in Poland,
  • Volkswagen HQ in Germany.

iHHC2 - hand held controller for Hillstone AC load bank control


The NEW iHCC-2 from Hillstone is a robust intelligent loadbank controller, that allows common connection of multiple load banks.


The controller allows "on the fly" setting and selection of the required load. 

The load can be quickly set from 0 to max load via 3 robust push buttons: x1 x10 x100.

The operator can also make fine adjustment in 1kw steps in real time via up down increment and decrement buttons.


The iHHC-2 allows for parallel control of up to 8 load banks. 

When multiple load banks are connected in a daisy chain loop, the single controller will control all the load banks.

Feature Upon initial start up of the load bank the display on the controller of the maximum available kw.

Feature THe NEW iHHC-2 uses a 4 line LCD display with high illumination showing 4 digit KW readings.

Feature The LCD supports an 270o viewing angle and allows viewing even in bright sunlight.

Feature The NEW iHHC-2 is compatible with the the 2 types of AC loadbanks models in the product range.

(i)     The standard loadbank displays the default load values at 415V to always be displayed


(ii)     The enhanced real time load display on the iHHC2 incorporates panel mounted power meter fitted to the load bank.  This display the actual load values on the generator or UPS system on the iHHC2.

Existing Customers hand held upgrades

For customers that have the old iHHC controller we can offer an low cost hardware upgrade to the new iHHC2.

We only require customers to supply the M36 serial number of the purchased load bank and we will arrange collection and replacement.

Understanding generator wet stacking problems

Part One from our series of informative load bank usage blogs

Regular load bank testing of your generator prevents damage or engine failure that can occur from running under load or below the WET STACKING LEVEL

Wet stacking - the problem:

Wet stacking occurs due to running the genset on a low load.  This in turn prevents the engine temperature running at the required design temperature, typically 100 - 200oC, and results with un-burnt fuel deposits being left and building up in the engine cylinders. 

This fuel build up will over time line the combustion chamber cylinders and cause a reduction in the engine ratings and efficiency, which will ultimately cause premature failure of the generator.

Wet stacking - the solution:

Running the generator on load of 30% - 100% of the genset rating will allow the engine to reach the recommend operating temperature.  This will burn off the choke deposits and discharge lots of black smoke and maybe hot balls of carbon out of the exhaust.

Load banks can be used in two applications to prevent wet stacking, these are:

      (i)     100% load bank testing
As part of regular maintenance and after say running the load bank for 100 hours at low load the load bank testing for between 2 to 4 hours will be sufficient to clear the carbon deposits and prove the generator efficiency.

     (ii)     Installing a permanent load bank with auto load shedding.
A special controller is fitted to the load bank and the generator output to monitor and regulate the load to  ensure a minimum 30% load setting is always applied.

For a complete range of load banks for generator wet stacking testing - Hillstone are your ideal suppliers

Press article on rack mounted mini tower load banks at Telecity -Powergate

During the last quarter of 2010 Hillstone designed and supplied 2.2MW of 6KW 19" rack load banks in 122 portable mini towers, to Telecity Powergate datacentre facility in West London.

The following picture and supporting text was published on  the web site ZDNet UK

To get a picture of how the datacentre consumes power day-by-day, Telecity has hundreds of server-simulators (pictured) available that it uses to mimic the expected power load. 

This helps them find kinks in their power distribution systems before customers put their racks in. 

The modelling lets Telecity stress-test the power systems' response to demand spikes and expected loads.
