Retrofit & Enhancements

Upgrading ageing BMS & EPMS with zero downtime

ABEC retrofits and upgrades Building Management and Electrical Power Monitoring Systems in live, critical environments, including systems we didn't originally install, so an ageing platform doesn't turn into a bigger risk than it needs to be.

The common problem

The system that got
you this far wasn't built
for what's coming next

Many data centre BMS and EPMS platforms in service today were specified years, sometimes decades, before the loads they're now expected to manage.

Spare parts get harder to source, vendor support quietly thins out, and energy performance drifts the wrong way, all without a single dramatic failure to flag it.

The risk isn't that the system breaks tomorrow, it's that it keeps limping along while the facility around it takes on more load, more compliance requirements and more scrutiny than it was ever designed for.

20+ years: tenure of data centre BMS & EPMS installations driving retrofit demand have been in service

That’s well past the point most platforms were designed to run unmodified.

60–80% of a building's total energy consumption that still runs through that ageing system

A platform tuned for yesteryear's loads inflates far more than just the plant room budget.

200% growth by 2030

Global data centre electricity demand is projected to more than double by 2030. Ageing controls will be asked to manage far more than they were ever designed for.

How a retrofit works

Upgraded in place. Nothing switched
off to do it.

Platform Upgrades

Replacing or substantially upgrading an ageing BMS or EPMS platform, including systems ABEC didn't originally install, without a full rebuild.

Capacity & Efficiency Enhancements

Extending or optimising an existing system to support additional load, tighter energy targets, or new compliance requirements, without replacing the whole platform.

How the
process works

Assess

A full audit of the existing system, whoever installed it, mapping obsolescence risk, spare parts availability and the fastest wins available.

Plan

A phased upgrade plan built around 
your operational calendar, not the 
other way round.

Upgrade

Work carried out in stages within the live environment, so systems stay controlled and monitored throughout, not switched off and hoped back on.

Validate & Handover

Full testing against specification, documentation, and handover either to your team or into an ongoing ABEC maintenance contract.

Why clients choose ABEC for retrofit projects

We didn’t need to install it to fix it

ABEC retrofits and upgrades systems built by other
integrators, not just its own installed base. If your
current system was put in by someone else, that’s
not a barrier.

Live environment, not a shutdown

Retrofit work is phased and sequenced specifically
to keep a critical facility operating throughout,
rather than requiring downtime to complete.

Backed by the same team behind AWS,
AXA and Santander

Delivered by the same engineers, the same
accreditations and the same 22 years of BMS and
EPMS experience behind major projects.

Proof, not promises

Frequently asked questions

Do you only retrofit systems ABEC originally installed?

No. ABEC retrofits and upgrades BMS and EPMS systems regardless of who installed them originally.

Can this happen without taking our data centre offline?

Yes. Retrofit work is planned and phased specifically around keeping a live environment operational throughout, rather than requiring a shutdown.

What usually triggers a retrofit project?

Most commonly, an ageing platform reaching end of vendor support, a capacity expansion the current system can't handle, a compliance requirement the existing setup doesn't meet, or taking on a facility with an unfamiliar system after an acquisition.

How is this different from a new build?

A retrofit works within an existing live system and its constraints. A new build starts from a clean design. If you're not sure which applies, that's exactly what the first conversation is for.
