Every piece of equipment used in a classified hazardous area is only as safe as the power feeding it. An uncertified transformer or distribution unit is a genuine ignition risk, which is why temporary power in Zone 1, Zone 2, Zone 21, and Zone 22 environments has to run through equipment engineered specifically for those conditions. The Ex transformer from SAE Equip’s SA Powernet range is built for exactly that job.
What Is an Ex Transformer?
The SA Powernet Ex transformer delivers a continuous 3,800VA rating in a stackable, modular housing designed to integrate directly with the rest of the Powernet ecosystem, including splitter boxes and extension leads, so teams can build bespoke temporary power solutions on site. Standard transformers are not built to prevent arcing, overheating, or the ingress of flammable gases and dust into their internal components — the unit solves this with a fully sealed, IP66-rated enclosure and multi-standard EX certification.
Key Features of the Ex Transformer
- Modular, stackable design that integrates with other SA Powernet equipment
- IP66 rated for full waterproof and dustproof protection
- Built-in MCB overcurrent protection, with optional RCD leakage protection
- Operates continuously up to +55°C ambient temperature
- Compact and lightweight at 60kg (excluding cable) for easier site handling
- Plug-and-play configuration with multiple voltage and plug options
- Externally resettable for quick recovery after a protection trip
Certifications
The unit carries ATEX, IECEx, UKEX, and INMETRO certification for Zone 1, 2, 21, and 22 areas, with an Ex db eb IIC T6 Gb rating. Full certification detail is published on the manufacturer’s official Ex transformer product page.

Why Choose the Ex Transformer from Daly Middle East
Daly Middle East stocks the unit locally for the UAE and GCC market, with rental options for short-term shutdowns and turnarounds. Because it shares the same modular design as the rest of the SA Powernet range, it can be paired with other certified power distribution equipment to build a bespoke setup for your site. Browse the portable transformers range or the wider power solutions category.
How to Choose the Right Ex Transformer for Your Site
Start with your load requirements: the 3.8kVA rating on this unit covers most portable tool and lighting loads on a typical hook-up or turnaround, but larger loads may need multiple units distributed across a site rather than a single transformer. Next, check what input supply is actually available — 230VAC via a 16A plug, or 400VAC via a 32A plug — since this determines how the unit connects into your existing distribution setup.
Because the unit is designed to stack and clamp together with other SA Powernet equipment, it is worth planning your full power distribution chain before ordering — pairing a transformer with splitter boxes and extension leads from the same range keeps connection points consistent and certified end to end, rather than mixing in unrated adaptors partway through the chain. Also confirm whether you need the optional RCD leakage protection in addition to the built-in MCB overcurrent protection, particularly for wet or washdown-prone areas.
Renting vs Buying an Ex Transformer in the UAE and GCC
Temporary power needs for shutdowns and hook-up work rarely justify a large permanent fleet, which is why hire is the default choice for many contractors sourcing this equipment through Daly Middle East. For sites running continuous maintenance or commissioning work, however, owning a core set of certified power distribution units can reduce dependency on hire availability during busy turnaround seasons across the GCC.
Safety Checks Before Every Deployment
Before connecting any temporary power equipment in a classified area, confirm the certification label matches your site’s zone classification, inspect cables and connectors for wear, and check that the MCB and any RCD protection are functioning correctly. It is good practice to log a pre-use inspection alongside your permit to work, especially during shutdowns and turnarounds when units are moved between multiple locations across a short window. Keep connections consistent with certified plug and socket types throughout the chain — mixing in an uncertified adaptor partway through undermines the protection the rest of the system provides.
Daly Middle East’s technical support team can advise on inspection intervals and safe configuration for hired and purchased power distribution equipment alike.
