ABOUT QED

A Northern Ireland fabricator built around one job: enclosing power equipment properly.

Qualmet Engineering & Design specialises in the detailed design and manufacture of industrial generator enclosures and offsite plant rooms, supplying construction and manufacturing clients across the UK.

Every project runs through our own 3D design office before it reaches the shop floor, so what gets built matches what got signed off — and every enclosure that leaves Moira has been floor-bund immersion tested, with all pipework and tanks pressure tested and certified on our own equipment.

WHAT WE BUILD

Two product lines, one design office.

Every enclosure starts as a steel chassis and is built out to suit the plant it houses — clad, louvred and finished for the site it's going to.

01
Sound-attenuated generator enclosure with louvred cladding
01 — GENERATOR ENCLOSURES

High-specification sound-attenuated generator enclosures.

Built to suit engine sizes and noise-suppression levels ranging from standby to prime power installations. Every enclosure is immersion tested for floor bunding, with all pipes and tanks pressure tested and certified in-house before the set leaves our yard.

02
Steel chassis and frame for an offsite plant room, in the Moira workshop before cladding
02 — OFFSITE PLANT ROOMS

Offsite manufactured plant rooms, built complete.

Supplied as a steel chassis, built out internally and clad in timber or Kingspan panel to suit the site. Housing heating plant, air conditioning, electrical transformers, compressed air systems, pumps and motors — fitted out and tested off-site, then delivered road-ready throughout the UK so commissioning on site is fast and predictable.

ACOUSTIC TESTING

We test the noise reduction before it ever reaches site.

Every generator enclosure is trialled with its engine running, so the acoustic performance is proven, not assumed.

  • 01

    Louvred intake & discharge design

    Acoustic louvre panels manage cooling airflow in and out of the enclosure while attenuating noise at the openings — the hardest part of any silenced enclosure to get right.

  • 02

    Engine-running test, in our yard

    Enclosures are tested with the housed engine live before dispatch, not modelled on paper — what you see on the video is the enclosure doing its job.

  • 03

    Built to the suppression level you need

    Panel build-up and exhaust silencing are specified to the engine size and the site's noise limits, whether that's a residential boundary or an industrial compound.

HOW A PROJECT RUNS

From drawing to delivered unit.

01

Design

3D solid modelling in-house, importing client CAD/ACAD files where needed, with full manufacturing drawings issued for sign-off.

02

Fabricate

CAD/CAM output drives our plasma profiler and press brake directly, built by coded welder-fabricators.

03

Test

Floor-bund immersion testing, pressure-tested pipework and tanks, and engine-running acoustic tests before anything ships.

04

Deliver

Enclosures leave Moira complete and site-ready, transported UK-wide on our own low-loaders.

THE WORKSHOP

Cutting edge equipment, near Moira.

25,000 sq ft of production floor, run by coded welder-fabricators experienced across stainless, aluminium and mild steel.
