Gulf Union Ozone carries six electrical enclosure families to IEC 60529, NEMA 4X, ATEX, and IECEx standards — with complete certification documentation for every enclosure supplied to Saudi Arabia industrial projects.

Type 01

GRP Fibreglass Enclosures — IP65/IP66

Glass-reinforced polyester (GRP) fibreglass electrical enclosures to IEC 60529 IP65 and IP66 — the primary choice for outdoor, coastal, and corrosive industrial environments in Saudi Arabia where carbon steel would require frequent repainting and corrodes rapidly in salt-laden marine air. GRP enclosures are non-corroding, non-magnetic, UV-stable, lightweight (up to 60% lighter than equivalent steel), and self-extinguishing (UL 94 V-0 flame class). Standard range: 80×80×55mm (small instrument box) through 600×500×200mm (large marshalling box). Colour: RAL 7032 pebble-grey standard. Lid fixing: 4× stainless steel 316L quarter-turn or screw fixings. Gland plate: removable, drilled on request. Internal DIN rail and terminal block mounting available. Used extensively in Saudi Arabia oil and gas instrument loops, coastal pump stations, water treatment junction boxes, and desalination facility field wiring. Transparent lid polycarbonate versions also stocked.

Type 02

Stainless Steel Junction Boxes — 316L, IP65/IP66

AISI 316L stainless steel junction boxes and instrument enclosures to IEC 60529 IP65 and IP66 for chemical process plants, desalination facilities, food and pharmaceutical production, and marine environments in Saudi Arabia. 316L (low-carbon molybdenum-alloyed SS) provides superior pitting and crevice corrosion resistance over standard 304 SS — essential in chloride-rich coastal environments around Jeddah, Jubail, and Yanbu. Standard range: 100×100×75mm through 800×600×300mm. Lid: full-perimeter EPDM gasket, countersunk M5 or M6 SS screws. Internal: M5 earth stud, 35mm DIN rail pre-fitted on larger sizes. Gland plate: 2mm SS, pre-drilled or blank. Wall-mounting: 4× welded M6 stud feet on rear panel. Used for instrument junction boxes, thermocouple head boxes, cable termination boxes, and small local control panels. Brushed (2B) or mirror-polished (BA) finish on request for food-grade applications.

Type 03

Steel Distribution Boards & Control Panels — IP55/IP65

Powder-coated mild steel electrical distribution boards, wall-mount and floor-standing control panel enclosures, and multi-door cubicles for motor control, power distribution, and instrument panel applications in Saudi Arabia. Finish: RAL 7035 light grey powder coat (60–80µm), textured inside and outside, UV-resistant. IP55 wall-mount enclosures: 300×200×150mm through 1200×1000×300mm — used for local motor control panels, lighting distribution boards, and small instrument panels at outdoor pump stations and plant areas. Floor-standing multi-door cubicles (IP31/IP54): 600mm–1200mm wide × 600mm deep × 2000mm high — for MCCs, main distribution boards, and power control panels in substations and electrical rooms. Mounting plate: anti-corrosion zinc-phosphate pre-treated, RAL 7035 powder coat. Cable entry: bottom and top gland plates, removable. Supplied with internal 35mm DIN rail mounting strips, 63A–400A busbar pre-fitted on distribution board versions.

ATEX and IECEx certified explosion-proof electrical enclosures for Zone 1 (Ex-d flameproof) and Zone 2 (Ex-e increased safety) hazardous areas in Saudi Arabia oil and gas, refinery, and chemical plant environments. Ex-d (flameproof) enclosures: cast aluminium or GRP body, IP65 or IP66, Group IIA and IIB (standard) and IIC (hydrogen service) — used for junction boxes, marshalling boxes, pushbutton stations, and instrument housings in Zone 1 where electrical sparks could ignite flammable atmospheres. Ex-e (increased safety) enclosures: GRP and stainless steel, IP65, Zone 2 — for passive cable terminations, lighting distribution, and signal conditioning in Zone 2 designated areas. T4 (135°C) and T5 (100°C) temperature classes standard. All ATEX/IECEx units supplied with Ex certificate (IECEx certificate number), marking plate (e.g. Ex-d IIB T4 Gb), ingress protection test report, and installation instructions.

FAQ

Frequently Asked Questions — Electrical Enclosures Saudi Arabia

What IP rating enclosures do you supply for outdoor industrial use in Saudi Arabia?

Gulf Union Ozone supplies electrical enclosures and junction boxes in IP65, IP66, and IP67 protection ratings to IEC 60529 — the standard grades required for outdoor and wet-process industrial installations in Saudi Arabia. IP65 (dust-tight, protected against low-pressure water jets) is the minimum for outdoor junction boxes and instrument enclosures on Saudi Arabia pipe racks, pump stations, and outdoor MCCs. IP66 (protected against powerful water jets) is specified for enclosures exposed to wash-down, monsoon rain, or coastal spray — particularly on Jeddah and Yanbu coastal sites. IP67 (submersion to 1 metre for 30 minutes) is used in floor-mounted enclosures in water treatment plants and sump pump areas where temporary flooding is possible. All our GRP, stainless steel, and powder-coated steel enclosures are IP-rated and certified, with ATEX Zone 1/2 variants for hazardous areas.

Do you supply ATEX IECEx explosion-proof enclosures for Zone 1 and Zone 2 hazardous areas in Saudi Arabia?

Yes. Gulf Union Ozone stocks ATEX and IECEx certified explosion-proof enclosures for Zone 1 (Ex-d flameproof) and Zone 2 (Ex-e increased safety, Ex-nR restricted breathing) applications in Saudi Arabia oil and gas upstream, refinery, petrochemical, and gas processing plant environments. Ex-d (flameproof) GRP and cast aluminium junction boxes for Zone 1 — Group IIA, IIB, and IIC; T4/T5 temperature class; IP65 and IP66. Ex-e (increased safety) stainless steel and GRP enclosures for Zone 2 where terminations and passive components are housed.
