Ecom Tab-Ex 03 DZ1 Zone 1/21 Hazardous Area Tablet

Overview

The Ecom Tab-Ex 03 DZ1 is a rugged, Zone 1/21 & Division 1 certified intrinsically safe Android tablet purpose-built for facility engineers, technicians, and inspectors who must carry full computing power directly into a classified hazardous area. Built on the third-generation Tab-Ex platform from Ecom Instruments – part of the Pepperl+Fuchs Group – the Ecom Tab-Ex 03 DZ1 is based on the Samsung Galaxy Tab Active3 hardware, giving plant personnel an 8″ multitouch Android device that operates reliably with gloves on, in direct sunlight, and in the presence of flammable gases, vapors, or combustible dusts.

As the official authorized partner and exclusive regional representative for Ecom Instruments, Seven Star LLC proudly supplies the Ecom Tab-Ex 03 DZ1 to refineries, LNG terminals, offshore platforms, and petrochemical complexes across the Sultanate of Oman and the wider GCC. Every unit shipped through Seven Star LLC carries full ATEX and IECEx documentation, manufacturer warranty, and local technical support, giving plant managers in Muscat, Sohar, and Salalah a dependable, factory-backed supply channel instead of relying on unauthorized grey-market imports.

Operating Principle of the Ecom Tab-Ex 03 DZ1

Intrinsic safety in the Ecom Tab-Ex 03 DZ1 is achieved by strictly limiting the electrical and thermal energy available inside the enclosure so that no spark or hot surface generated during normal operation, or under fault conditions, can carry sufficient energy to ignite a surrounding explosive atmosphere. The device combines protection type Ex db ia IIC T6 Gb with dust protection Ex ia tb IIIC T80°C Db, meaning the tablet is validated for use in Zone 1/21 gas and dust atmospheres as well as Division 1 areas under NEC/CEC schemes once locally certified. Internally, energy-limiting circuitry, potted components, and a flameproof enclosure design work together so the Samsung Exynos processor, battery, and radios can run at full performance without breaching the ignition-energy threshold defined by the IIC gas group.

Because the safety function is designed into the circuit and enclosure rather than bolted on as an afterthought, the practical result for the end user is a tablet that behaves exactly like a standard Android device – full multitouch response, camera, GPS, and wireless connectivity – with no derating of processing power and no special handling procedure required before entering the classified area. There are no purge cycles, no external barriers to wire, and no loss of functionality; the explosion protection is transparent to daily use, which is precisely what makes the Ecom Tab-Ex 03 DZ1 practical for technicians who move in and out of hazardous zones dozens of times per shift.

Engineering Design of the Ecom Tab-Ex 03 DZ1

The Ecom Tab-Ex 03 DZ1 is housed in an impact-resistant polycarbonate and elastomer chassis rated IP64, further hardened to MIL-STD-810H shock and vibration standards, and finished with a reinforced bezel that protects the 8″ WUXGA (1920×1200) display from drops and knocks in the field. The capacitive touchscreen, rated at 480 nits brightness, remains fully operable with industrial gloves, in wet conditions, and in direct outdoor sunlight, while the bundled S Pen allows precise digital sign-off of inspection checklists and permit-to-work forms without removing PPE.

Inside, an Exynos 9810 octa-core processor (4 × 2.7 GHz + 4 × 1.7 GHz) paired with 4 GB RAM and 64 GB of expandable storage runs Android with Samsung Knox security, giving IT departments the same mobile-device-management tools used on consumer Samsung fleets. A removable 5,050 mAh battery delivers up to 11 hours of continuous runtime, and a freely programmable emergency button on the housing can be mapped to push-to-talk, man-down alarms, or a direct call to the control room. Wi-Fi 802.11ac, Bluetooth 5.0, NFC, and an optional LTE variant cover the connectivity needs of most brownfield and greenfield instrumentation networks, while the Samsung DeX mode lets the same tablet dock to an external monitor and keyboard for full desktop-style report writing back in the office.

Key Features

The Ecom Tab-Ex 03 combines certified explosion protection with genuine day-to-day usability, and its key features reflect that balance between compliance and productivity:

• Certified for Zone 1/21 gas and dust atmospheres and Division 1 areas, covering the majority of classified process units, tank farms, and loading terminals.
• Built on the Samsung Galaxy Tab Active3 platform, giving access to a mature Android Enterprise Recommended ecosystem and long-term firmware support.
• 8″ capacitive multitouch display operable with gloves, wet fingers, or the included S Pen for signature capture.
• Exynos 9810 octa-core processor with 4 GB RAM handles modern inspection, CMMS, and augmented-reality applications without lag.
• 5,050 mAh removable battery provides up to 11 hours of runtime across a full shift, with a hot-swap option to avoid downtime.
• Samsung Knox multilayer security protects plant data and integrates with existing enterprise mobility management platforms.
• Freely programmable emergency button enables one-touch alarm calls, push-to-talk, or man-down notification for lone workers.
• Samsung DeX support turns the tablet into a full desktop workstation when docked, eliminating the need for a second device back at the office.

Industrial Applications

The Ecom Tab-Ex 03 DZ1 is deployed wherever technicians need continuous computing access inside a classified area rather than stepping outside to record readings from memory. Typical use cases include mechanical integrity inspections in refinery process units, digital permit-to-work sign-off at tank farms and loading gantries, gas detector calibration logging in offshore module rooms, and asset walkdown surveys in petrochemical and LNG facilities where paper-based records introduce delay and transcription error. Its Android platform also supports augmented-reality overlays via Google ARCore, useful for remote expert assistance during turnaround and shutdown campaigns.

As the officially authorized partner for Ecom Instruments, Seven Star LLC distributes the Ecom Tab-Ex 03 DZ1 to operators across Oman’s industrial zones, including the Sohar and Salalah free zones, Duqm’s refining and petrochemical cluster, and upstream production sites throughout the interior. Regional stockholding in Muscat means replacement units and accessories can reach GCC customers quickly, minimizing the operational impact of a damaged or lost device during an active turnaround.
