UPS Enclosures

Fabricated steel and aluminium enclosures for uninterruptible power supply systems installed in data centres, hospital plant rooms, industrial control facilities, and commercial critical power environments. The environment is controlled and indoor, which shifts every design priority away from weather resistance and toward EMI shielding integrity, internal thermal management, cable entry density, acoustic performance, and the cosmetic standard expected of equipment in occupied, visible spaces. Manufactured to your UPS design, with EMC construction, finish specification, and cable management provisions confirmed before first article.

Primary Material — Steel

Cold-rolled close-annealed (CRCA) steel, 1.5–3.0 mm; IS 513 / EN 10130 CR4. Zinc phosphate pre-treated before powder coat.

Primary Material — Aluminium

6061-T6 plate and extrusion for lightweight format enclosures; 5052-H32 for formed sheet panels

Sheet Thickness

Structural frame: 2.0–3.0 mm; side and door panels: 1.5–2.0 mm; internal baffles: 1.0–1.5 mm

Rack Mounting Flange Tolerance

Rack mounting hole position: ±0.2 mm; flange flatness ≤0.3 mm over full height; 19″ / 23″ EIA standard

Shielding Effectiveness

Up to 60 dB attenuation, 10 MHz to 1 GHz; achieved through continuous joint bonding and conductive door gaskets

*First-run lead times include EMC construction review and both dimensional and cosmetic FAI gates. Re-orders on established programmes run on shorter lead times with all specifications, tooling, and finish standards retained.

Product Description

UPS inverter and rectifier switching generates significant electromagnetic emissions across a wide frequency range. In a data centre, those emissions propagate through the enclosure walls into adjacent server rack electronics unless the enclosure construction specifically controls them. EMI shielding effectiveness depends not on material selection alone but on joint construction, every panel seam, door interface, cable entry aperture, and ventilation opening is a potential emission path. Frigate’s EMC construction review at DFM stage identifies and addresses all joint continuity gaps before fabrication begins, rather than discovering shielding deficiencies during the final compliance testing.

Panel Joint Construction

Conductive beryllium copper or stainless finger-strip gaskets at all panel seams and door perimeters; no untreated gaps in shell

Door EMC Gasket

Continuous conductive finger-strip or EMC foam gasket at full door perimeter; contact force maintained across hinge and latch deflection range

Airflow Configuration

Bottom inlet / top exhaust; front inlet / rear exhaust; or forced-air fan-assisted per OEM thermal model

Fan Mounting Provision

Fan mounting frame and blanking panel provisions per OEM fan unit interface drawing; vibration isolation mounts available

Operating Temperature

0°C to +40°C continuous (IEC 62040-1 standard UPS environment); extended range to −5°C / +50°C available

IP Rating

IP21 (standard indoor); IP31; IP41; IP54 (dusty industrial environment). Variant confirmed per installation environment specification

Door Seal

EPDM or PVC compression seal at door perimeter for IP31 and above; combined with conductive EMC gasket where IP and EMC both required

Surface Preparation

Zinc phosphate pre-treatment (steel) or chromate conversion (aluminium); weld spatter removal; panel surface flatness controlled before finish

Powder Coat

Polyester powder coat 60–80 µm DFT; RAL colour per OEM specification; cosmetic grade surface — no visible panel waviness, weld witness marks, or inclusion defects on external faces

Environmental Compliance

RoHS 3; REACH SVHC <0.1% w/w; WEEE compliant; suitable for CE-marked UPS system integration

Technical Advantages

Tower format enclosures serve compact single-phase UPS units from 1 kVA to 20 kVA, freestanding, front-access, with top or rear cable entry. The cosmetic standard for tower format is high because these units are frequently installed in visible office and server room environments.

Rack-mount enclosures serve 1U to 12U rackmount UPS units integrated into standard 19″ or 23″ equipment racks, dimensional accuracy at the rack mounting flanges is critical, as rack interference on installation is a common quality complaint that traces directly to flange position tolerance at manufacture. Floor-standing cabinet enclosures serve three-phase modular UPS systems from 20 kVA to 800 kVA, large-format steel weldments with front and rear door access, multiple cable entry zones, and internal module rail systems for scalable UPS module installation.

Having Doubts? Our FAQ

Our UPS fails EMC compliance testing and we suspect the enclosure joint construction. What does Frigate review at DFM stage?

Frigate’s EMC construction review covers every joint in the enclosure shell, panel seams, door perimeter, access panel interfaces, cable entry plate bonding, and ventilation aperture treatment. The review identifies gaps in shielding continuity and specifies finger-strip gasket positions, bonding contact areas, and gland plate construction before fabrication begins. EMC failures that surface at compliance testing almost always trace to joint design decisions that were fixable at the drawing stage.

We need both IP54 sealing and high EMC shielding on the same enclosure. Can those coexist?

Yes, IP sealing and EMC shielding use different gasket systems that can be combined at the same interface. The IP seal handles liquid and dust ingress; the conductive EMC gasket handles electromagnetic continuity. Both are specified and positioned at the DFM review stage so the door interface carries both functions without compromising either.

Our rack-mount UPS panels don't align properly in customer racks. Can Frigate hold tighter rack flange tolerances?

Rack flange misalignment on installation traces directly to hole position tolerance at manufacture. Frigate holds rack mounting hole position to ±0.2 mm, CNC-drilled on a dedicated fixture referenced to the enclosure datum, not transferred from the panel flat pattern. This is confirmed by CMM measurement at first article and verified by AQL sampling in production.

We have acoustic noise requirements for hospital installations. How does Frigate approach that?

Acoustic performance is treated as a designed-in feature, not an add-on. Lining material, thickness, facing sheet, and duct insert geometry are all confirmed against the OEM’s noise level requirement at DFM stage. The acoustic specification is locked at first article alongside the dimensional and cosmetic approval — not addressed after the enclosure is in production.

We're re-sourcing an existing UPS enclosure design. What does Frigate need to assess compatibility?

Send the existing drawing or STEP model, current supplier’s quality issues if known, and your annual volume. Frigate will assess manufacturability, confirm whether the EMC construction is adequate for the shielding requirement, and identify any improvements to the existing design that address known quality issues at the same time. Re-sourcing with a DFM improvement opportunity is more efficient than re-sourcing to exact-as-was.
