Critical cooling / CIRE Air Conditioning

Data centre &
server room cooling.
Engineered around
your infrastructure.

Specialist cooling for data centres, SER rooms, hub rooms, server rooms and comms rooms. From compact IT spaces to larger computer rooms, CIRE helps you plan, install and care for the cooling your equipment depends on.

Cooling for the equipment behind your business

Your IT keeps working.
Plan its cooling to match.

A small comms room can be as important to a business as a large server suite.

Equipment heat loads, rack layout and operating hours shape the cooling requirement. We work with facilities teams, IT teams and project consultants to establish a practical scope for new installations, upgrades and replacements.

Start with the room, the equipment and the required resilience. Then select the cooling solution.

Specialist spaces. Individual requirements.

From one hub room
to a data centre.

Computer room cooling should reflect what is installed today, what may be added tomorrow and the consequences of losing cooling.

01 / COMPUTE

Data centre cooling

Cooling installations and upgrades for data halls and computer rooms, coordinated with the project’s capacity, airflow and resilience requirements.

02 / IT INFRASTRUCTURE

Server room cooling

Dedicated cooling for rooms housing servers, storage and associated IT equipment, with attention to rack heat loads and the route of supply and return air.

03 / COMMUNICATIONS

Comms room cooling

Air-conditioning solutions for communications rooms and network equipment, considering restricted space, access and continuous equipment operation.

04 / EQUIPMENT ROOMS

SER room cooling

Cooling for SER rooms within commercial buildings and campus developments, with equipment schedules and room functions confirmed against your project information.

05 / NETWORK DISTRIBUTION

Hub room cooling

Cooling for network hubs, switching equipment and distributed IT rooms, planned around local loads and the wider building’s facilities arrangements.

06 / SMALLER SPACES

IT closets & edge rooms

Space-conscious options for smaller computer and network spaces, with suitable heat rejection, service access and provision for future changes.

Understand the options

The right cooling.
In the right place.

Selection follows a review of the actual load and site conditions. The options below explain the different approaches we can discuss with your project team.

01 COMPACT ROOMS

Dedicated DX cooling

Direct-expansion systems use refrigerant to transfer heat from the room to an air-cooled outdoor unit. Suitable equipment can serve smaller server, SER and comms rooms.

Selection focus: sensible cooling capacity, continuous-duty suitability, low-ambient cooling operation and available installation space.

02 PRECISION COOLING

DX CRAC systems

Computer room air-conditioning units provide dedicated precision cooling using DX refrigeration with air-cooled outdoor heat rejection. Air-delivery arrangements and controls are selected to suit the computer room.

Selection focus: room load, temperature and humidity requirements, airflow direction and service access.

03 RACK-FOCUSED COOLING

DX in-row cooling & containment

Direct-expansion in-row units bring cooling closer to rack heat loads. Hot- or cold-aisle containment helps separate air paths and limit hot-air recirculation, where compatible with the room design.

Selection focus: rack density, air distribution, layout constraints and integration with the existing cooling strategy.

Look beyond the nameplate capacity

Capacity. Airflow.
Resilience.

Additional cooling units only provide useful resilience when the complete arrangement supports it. We help define the installation and commissioning scope around the agreed design.

Duty, standby & N+1

Where specified, coordinate unit rotation, standby operation and failure response. N+1 means one additional capacity component beyond those needed for the design duty; power, controls and heat rejection also need consideration.

Controls & alarm interfaces

Agree temperature sensing, alarm outputs and links to the site’s monitoring or BMS team. Interface responsibilities and test requirements are established before installation.

Airflow & future load

Consider rack inlet conditions, obstructions and recirculation alongside the current heat load. Allow for planned equipment changes within an agreed capacity strategy.

Working in operational rooms

Plan access, isolations, changeover sequences and any temporary cooling requirements with your facilities and IT teams before works begin.

CIRE delivery

A clear route
from brief to handover.

Installation, commissioning and ongoing care, with defined responsibilities at each stage.

  1. 01

    Review the brief

    Gather room layouts, load information, equipment details, operating requirements and access constraints.

  2. 02

    Agree the solution

    Coordinate equipment selection, routes, controls interfaces and the installation scope with the project team.

  3. 03

    Install & commission

    Deliver the agreed works, carry out specified checks and record commissioning results for handover.

  4. 04

    Plan ongoing care

    Agree a maintenance programme suited to the equipment, environment and operating hours.

Questions before you specify

Get the brief
right from the start.

Can a normal office air conditioner cool a server room?

Suitability needs to be checked rather than assumed. IT rooms may require continuous cooling throughout the year, specific sensible capacity, suitable airflow and failure-response controls. The selected equipment must support the intended operating conditions.

How do you size cooling for a server or comms room?

Start with the equipment heat output, room conditions and planned growth. Rack layout, airflow and the required resilience also affect selection. Floor area alone does not establish the correct cooling capacity.

Can you replace cooling in a live equipment room?

We can discuss a phased replacement scope with your team. Any changeover needs an agreed plan for access, isolations, operating risks and continuity of cooling, including temporary arrangements where required.

Do you cover small SER rooms and hub rooms?

Yes. We welcome enquiries for small SER rooms, hub rooms, comms rooms and server rooms as well as larger computer and data-centre environments across London, Kent and the South East.
