HAFEX Suppression for Data Centres & Comms Rooms
Protecting a server room, comms cabinet, or switchboard from fire without pressurised gas cylinders? TFP Electrical Fire & Security installs HAFEX condensed aerosol suppression — a 15-year shelf-life system needing no pipework, activated by fire panel or thermal bulb. BAFE-accredited, serving Bath to London. Free survey: 03301 331 817.
Enclosed electrical spaces — comms cabinets, UPS rooms, switchboards, and server racks in the commercial buildings TFP works on across Bath, Bristol, Swindon, Oxford, Birmingham, Reading, Cardiff and London — are exactly the environments where a traditional gas suppression system becomes a headache. Gas systems need pressure vessels, dedicated pipe runs, and floor or ceiling void space that older commercial buildings and retrofitted comms rooms often don’t have. HAFEX condensed aerosol removes that constraint: the units mount directly in the protected space, connect electrically, and need no pressurised pipework at all.
TFP designs and installs HAFEX as a direct replacement for gas suppression on projects ranging from single comms cabinets to full-floor switchboard and generator room protection — the same multi-discipline fire and electrical scope TFP delivered across the five floors of Armada House in Bristol, where fire alarms, electrical distribution, and data infrastructure were designed and installed as one coordinated package. Because HAFEX units can be activated from a fire alarm panel or a stand-alone thermal bulb, TFP integrates suppression directly into the same BS 5839-1 fire detection systems it already designs and commissions on-site.
TFP is BAFE-accredited and NSI Silver certified, with all electrical specialists working to NSI Gold level. Surveys and quotations are free and no-obligation, and every installation carries TFP’s 12-month workmanship warranty. Call 03301 331 817 to arrange a site survey for your server room, data centre, or plant space.

WHY CHOOSE TFP FOR HAFEX INSTALLATION
Electrical-First Installation HAFEX needs no pipefitting — just correct electrical integration with the space’s power and fire alarm systems. That’s TFP’s core discipline: NICEIC-approved electrical work is what the company is built on, so the HAFEX install is handled by the same electricians wiring the room, not a separate mechanical subcontractor.
Fire Detection Already In-House TFP is BAFE-accredited and installs fire alarm and detection systems from Grade A to Grade D to BS 5839-1. Because HAFEX can trigger from a fire panel, TFP can specify, wire, and commission detection and suppression as a single system rather than two contractors handing off between them.
Single Contractor for the Whole Room Server rooms and comms cabinets usually need more than suppression — data cabling, UPS, CCTV, and electrical distribution too. TFP’s Armada House project (Bristol, five floors, two-year programme) delivered electrical, fire alarms, intruder alarms, EV charging, AOV, AV, data cabling and CCTV as one scope, which is the same multi-discipline approach applied to HAFEX-protected spaces.
No-Obligation Site Survey Retrofitting suppression into an existing comms room or switchboard cupboard depends entirely on the space available — TFP surveys the room in person, free of charge, before quoting, so the recommendation reflects what will actually fit.
FAQs
HAFEX needs no pressure vessels, no piping runs, and far less room than a gas cylinder-and-pipework system — the units mount directly in the space and connect electrically. TFP fits it as a direct like-for-like replacement in server rooms, comms cabinets, and switchboards where floor or ceiling void space for pipework simply isn’t available.
HAFEX can be activated either from a fire alarm panel or a stand-alone thermal bulb, giving two integration routes depending on whether the room already has detection installed. TFP, being BAFE-accredited for fire alarm design to BS 5839-1, can wire HAFEX into an existing panel or specify a self-contained thermal-bulb unit for a standalone cabinet.
Yes — HAFEX is non-toxic, non-corrosive, and non-harmful to people and animals in the space, and it doesn’t deplete the ozone layer. Unlike some gas agents, no evacuation-critical toxicity profile applies, though TFP still designs activation and signage around your site’s normal safe-working procedure.
No — HAFEX leaves no residue after activation, which is one of the main reasons it suits comms rooms, data centres, and switchboards where cleanup after a discharge could otherwise mean replacing sensitive equipment. This also keeps post-incident downtime lower than powder-based alternatives.
TFP covers Bath, Bristol, London, Swindon, Oxford, Birmingham, Reading and Cardiff for HAFEX design and installation, alongside its existing electrical, fire and security work in those areas. Surveys are free and no-obligation — call 03301 331 817 to check coverage for your site.
HAFEX is designed for minimal maintenance and carries a 15-year shelf life, so routine servicing is far lighter than a pressurised gas system, which typically needs periodic pressure testing and cylinder weighing. TFP can include HAFEX checks as part of a wider fire and electrical maintenance visit rather than a separate callout.
In most cases, yes — because there’s no pipework or pressure vessel to route, HAFEX typically installs with far less disruption than retrofitting a gas system into an existing cabinet or plant room. TFP surveys the specific space first to confirm fit and the correct unit size before quoting.
