FEL Group have over 20 years of experience installing comfort cooling, VRF/VRV, refrigeration and ventilation systems. We serve a multitude of sectors.
Working with our partners, we offer a turnkey solution for data centers, from the cooling plant and controls to the IT network infrastructure, building construction works, electrical power/lighting, hot/cold aisle containment, BMS, DCIM, fire suppression, life safety and security systems.
Our proven planning model for project management ensures that the installation of your solution runs to time and budget. Our expertise covers a wide range of project types. We offer our customers the ability to attend our design team meetings together with site progress meetings.
From a single split air conditioning unit to central chiller plant, and from chilled water to direct expansion (DX) refrigerant systems, FEL Group’s dedicated team will design, install and commission a system that is built around your business requirements.
“ FEL Group (following a tele/con between Michelle Wainwright and me) completed a full building, room to room inspection for missing tiles, builderâs snags and covered smoke detectors. The tele/con occurred at 14:00hrs and at 15:00hrs an FEL Group builder (Jim) arrived at site and carried out the fitting and replacement of tiles, even in areas FEL Group had clearly not worked in. This was an exceptional response given the short notice on a Friday afternoon, many thanks to Michelle Wainwright, FEL Group, and Lodestone (FEL Groupâs builder contractor). Both Keith and Jim went the extra mile and displayed once again the willingness to assist and get the job done, an attitude that is becoming synonymous with FEL Group and their sub-contractors. ”
“ FEL Group proved to be the right choice as contractor, and took up the challenge of completing the works (45 rooms across 6 floors and 3 roof levels) to a high standard in just 7 weeks, and when required, went the extra mile. It must be noted that during the tender stage, 2 of the prospective bidders (bigger companies than FEL Group) declined to tender due to the challenging programme. ”
“ This site is a new containerisation switch room, purposely built for the requirements for new housing growth within the Margate area, FEL Group provided the design concept in which the customer was delighted that the concept will back up the existing provision on site. From start to completion FEL and their associates have been professional in their work on and o site, and always maintained close contact with the local businesses ensuring that the construction works did not impede in any way on their business or customers. Safety is a key topic within the company and we have had no issues at all while FEL have carried out their installation and delivery works. ”
A client of FEL Group had an urgent requirement to facilitatesigni cant additional customer growth. A local MP announced that
the Governments desire was that “everyone in the UK to bene t from world-class connectivity no matter where they live, work or travel” this pledge was also given a very challenging short deadline and FEL Group were tasked to meet this demand with little exibility on timescales.
The concept of prefabricated modular and portable buildings is growing in popularity.Modular data centres can be designed and constructed to detailed speci cations in
a controlled factory environment. Pre-commissioned, they considerably reduce time on site normally spent validating the operation of services from cooling through to Monitoring software.
Modular data centres o er scalable growth of IT infrastructure and the exibility tomodify the design and size of future plans of development. Modular buildings arrive onsite ready to deploy, which in turn signi cantly reduce on site installation/programmecosts. Modular data centres by nature are relatively small, an optimised footprint isessential, leading to function speci c modules that can accommodate larger capacityracks and providing a greater kW per square metre ratio.

The existing site is a fully populated hub, that had no further room for any future IT server rack cabinets, a new build solutionwas the only option.
Logistically, there was a short driveway up to the site with a small car park. An external generator, fuel tank and unused green eld land owned by the client next to the existing site and car park. Filled with shrubbery and hedges this land backedonto a security fence which enclosed the whole site.
Outline planning permissions and landlord approvals were obtained to use this land as a potential solution using a new modular building concept to house the proposed customer growth. Once approved, a noise survey and a utility detection and mapping ground survey were carried out.
The next new challenge became evident when thesite was highlighted as being located within a Zetica high-risk bomb area with bomb strikes recorded close to the site.
This risk clearly needed to be mitigated immediately to comply with CDM regulations. An initial desk study was carried out which included a preliminaryUXO (Unexploded Ordnance) risk assessment whichenables the surveyors to quantify the risk further. An additional detailed survey of the UXO area wasundertaken with a suspicious object identi ed.Recommended procedures were undertaken in order to remove the object and make the ground safe and viable for the proposed works to continue.
The land was cleared, and a new trench wasexcavated to join with the existing DNO services route.A new paved footway and concrete slab were installed ready for the installation of the new modular data centre building.
The modular data centre installed features a wall structure that incorporated a mild steel, primed, structural frameworkto take the wind and lifting loads. The external wall skins were formed from zinc coated steel sheets with vertical and horizontal sti ening members to cater for the wind loading. A proprietary, modular raised ooring system was installed comprising of base-plate support adjustable pedestals complete with cruciform head and nominal 600mm x 600mm x 42mm access ooring tiles nished in antistatic vinyl.
The building was manufactured as to ensure e ective retention of the re suppression gas. The building also has a rating of IP54 with doors rated to IP4X. The options for optimum energy e cient cooling were explored. Direct “Free” coolingwas proposed; however, this site is situated in a coastal location, whereby directly supplied fresh air would bring saline saturated air into the technical space leading to increased levels of corrosion.
Various water chiller options were assessed but were soon rejected, as it was highlighted there was no permanent watersupply on site, plus energy calculations showed longer ROI’s. The cooling option selected that met the best energy pro le,with all the site constraints considered became DX InRows. Two Airedale LIR6042U-X240-0 InRow AHUs were installed in a new contained hot aisle within the modular building, with the option to add a third as the IT load is increased above the current requirement. The Airedale InRow AHUs featured EC fan motors, N+1 fan redundancy, refrigerant leak detection and microprocessor controls with graphical display.
The AHUs were to control on supply air temperature at 21°C. The associated outdoor condenser units for the AHUs were located at the rear of the building within a dedicated security cage, whilst still allowing space to permit future growth. Anadditional bene t for our customer for this particular modular solution, is that there is a potential requirement to move thisentire IT growth to another more suitable site in the future. This modular solution would therefore enable a faster timescale for this undertaking.
