Data centre in Slough - December 2015

"I am happy to advise that the guys who executed the task were extremely professional and solved a few last-minute challenges with excellent problem solving and determination...I look forward to future business."

Project overview

An existing, operational data centre with three generator halls in use, 2 generators in each room and one lying fallow was to be enhanced with further power requirements. Each of the existing rooms was to have a third generator incorporated into the existing system and the fallow room was to be equipped with three generators to provide back-up power to a newly commissioned data hall.

Equipment

6 no. Cummins C1675D5A standby rated generator sets. Inlet and outlet attenuation and associated ducting and motorised dampers. Supply air fans and associated controls. Day fuel tanks giving 8-hour autonomous run fed from existing bulk tanks. Full leak detection systems for each room. Exhaust systems installed from each generator to roof level following the external elevation of the building.

Controls

In each of the three existing generator rooms a third set was added to increase the standby capacity. The sets were arranged in an N+1 configuration with the Cummins MLD function being utilised to ensure stable load sharing and equal run hours across all three sets. The fourth room had 3 sets installed and these were set up in a similar manner. Each generator room provides backup power to separate data halls in the event of a failure of the utility supply.

Water treatment works in Harlow

"Thanks for arranging one of your engineers to attend site at short notice and assist with the identification of the missing telemetry signals... it made the task much quicker and allowed us to carry out the work within the planned site shutdown period."

Project overview

Theft of the original equipment necessitated the replacement of a standby generator at a water treatment works in Harlow, Essex.

CSL Power Systems were assigned with placing a Cummins C150D5 canopied generator inside an existing acoustic enclosure and encasing it in concrete blocks with reinforced concrete infill.

The existing enclosure had been damaged when the original equipment was stolen and the end section had been forcibly removed. Once the new set was inside the enclosure the end section was replaced and secured. The entire acoustic enclosure was then encased within a concrete block structure with rebars and concrete infill along with a concrete ring beam to the top level and steel beams across the roof section affording extra protection against further theft of equipment.

The generator was coupled to an existing bulk fuel tank and a new auto transfer switch replaced existing equipment.

A full test of existing and new systems was undertaken upon completion.

Equipment

1 no. Cummins C150D5a generator set in a standard enclosure and 1 no. Cummins G-Tech transfer switch incorporated into existing equipment and systems.

Controls

The generator provides stand by power to the water treatment equipment and in the event of a power outage the generator will start, and the transfer switch will change over to allow the generator to power all systems. Upon return of utility power, the transfer switch returns to utility bias and the generator run signal is removed.

Data Centre in Middenmeer, Holland

"We were very impressed with what you provided us from design to your installation team who done a great job"

Project overview

A large data centre was commissioned to be constructed for a world leading IT company. The standby power requirements for this facility consist of 20 Cummins C3500D5e generators and 4 Cummins C2000D5e generators in acoustic enclosures. Each set has an underslung base tank and local fill point local to the bund area below each generator enclosure. Each enclosure has a dedicated section located to one end which houses the generator switchboard.

Scope of supply

CSL Power Systems have been employed by Cummins Belgium to assist with the testing and commissioning period of this project and are supplying a team of specialist engineers consisting of electrical, mechanical and commissioning technicians as well as team management/coordination staff to assist Cummins' site-based managers and engineers with the smooth transition to hand over of the completed project.

CSL Power Systems have been working very closely with Cummins and their client in ensuring the robust site testing of each unit has been successfully completed ensuring each milestone was achieved to the satisfaction of all stakeholders ensuring each completion/handover is achieved and the smooth flow of the project is adhered to.

Data centre in Crawley, November 2016 – May 2017

"All CSL personnel were professional and courteous throughout the complete installation process."

Project overview

In 2014 a data centre was built close to Gatwick airport. The original design had all of the MV transformers, standby generators, air handling units and other items of plant situated on the roof of the structure. As a result of this design there were numerous penetrations through the roof fabric which resulted in leaks forming in the roof and subsequently water penetration into the data halls. To rectify the problem a further roof structure has been formed which covers all of the existing equipment to form a weatherproof solution to the initial problem.

Scope of works and supply

CSL Power Systems were employed by Cummins UK to supply and install air paths and exhaust extensions to originally installed equipment affording safe and functional operation of all installed generator equipment.

We manufactured and installed exhaust extensions terminating in a 90° bend to prevent water ingress into the engine of 8 containerised Cummins C2000 D5A generators. Our team manufactured and fitted the final weathering cowls to all 8 exhausts.

CSL Power Systems also manufactured and installed ductwork extensions to 2 no Cummins C500 D5 containerised generator sets providing combined air outlet/exhaust gas extraction to fresh air. All works had to be closely coordinated with other site operations to ensure no downtime to existing systems within the operational data centre occurred. CSL Power Systems also manufactured and fitted weathering details to the ducting where it penetrated the new roof level.

Chessington  - November 2014 and June 2016 (Phase 1 & 2)

"I would just like to compliment CSL on your professionalism and swift engagement at every stage of the way. I would recommend CSL to any future clients for all generator and data centre works."

Project overview

In 2014 Digital Realty took possession of a former distribution centre in Chessington with the intention of adapting the building to use it as a data centre. The project was carried out across two phases with two data halls being completed in phase 1, 2014/15 and the third data hall being completed in phase 2, 2016. The rooms allocated for the installation of the standby generators were of limited spatial allowance and this posed many obstacles as the equipment had to be installed in a strict sequence and as there was no storage space on site during the works the materials and equipment had to be delivered to suit the installation sequence. A crane had to be utilised to offload the generators within the tight constraints of the construction site.

Equipment

9 x Cummins C2000 D5A, 400 v diesel generator sets fitted with Cummins QSK 60 engines coupled to Stamford 400-volt alternators. Three generators were installed into each room with generator switch boards located within each generator room. The rooms were acoustically treated to achieve 65dB with any two sets running. Separate day fuel tanks were also installed, one per generator, within the generator room.

Controls

Each generator room has two switchboards which in turn provide back-up power to two LV switchboards. The generators are configured such that one generator feeds each generator board with the third generator acting as a swing set that can feed either generator switchboard to offer further back up should either of the initial standby generators fail, there is also facility to rotate the swing set to ensure equal run time across each of the three generators in each room.
