Key elements of data centres designed and built by Procol

Data centre construction


We can undertake and manage the entire construction process, and aim to make the build of your data centre smooth and stress-free.

Our specialist technical expertise in this area has been put to good use on many occasions, including ongoing projects for a global data and telecoms supplier.

Air conditioning in a data centre

Air conditioning

Our in-house team designs and installs high-efficiency cooling systems from 5kw to 5MW, with inbuilt redundancy levels to meet your requirements.

As an independent supplier, we create bespoke solutions that utilise technologies ranging from inverter-driven direct expansion, and indirect free-cooling chilled water, through to direct fresh-air free cooling with DX backup.

Power supply for a data centre


Our M&E expertise makes us ideally placed to design and co-ordinate all aspects of the power supply for your data centre.

We frequently manage the installation of the power train from the HV transformer, switchgear, generators and UPS, right down to rack level inside the data centre. We can also take care of any associated small-power works.

Cooling system for a data centre

Energy efficiency

We can help you minimise the energy costs in your data centre.

For example, we specify and install innovative and bespoke solutions such as lighting systems with money-saving environmental controls, and direct and indirect free-air cooling systems that are considerably cheaper to run than traditional direct-expansion or chilled-water systems.

Project manager


We are experienced in constructing secure environments to high levels of Government accreditation, including the design and fabrication of specialist components such as Billinghurst grilles.

A high proportion of our staff are cleared to SC for the purposes of this work. We are also becoming increasingly involved in data centre projects of a List X standard.

Backup generator for a data centre

Redundancy and power protection

It’s important that your data centre remains unaffected should the mains supply fail. So we work closely with our consultants and switchgear, generator and UPS suppliers to design, supply and install power supply systems with a high level of resilience.

Our work in this area includes experience of supplying and managing power, generator and fuel-system installations up to 6MW (N+1).

Fire protection equipment being installed in a data centre

Fire protection

We manage the installation of fully integrated fire-detection and gas-extinguishing or suppression systems.

These include IG 55 and nitrogen water mist for generator rooms, as well as VESDA early warning systems to detect very early signs of overheating or fire in technical spaces.
