Industry Overview

Safe Operation in Hazardous Environments

Oil and gas operations involve handling flammable substances that create explosive atmospheres. ATEX Directive 2014/34/EU requires equipment used in potentially explosive environments to be certified for safety. Our ATEX-certified water treatment systems ensure safe, reliable operation in Zone 1 and Zone 2 hazardous areas while delivering effective wastewater treatment performance. Each treatment package is built and documented to support the operator’s DSEAR/ATEX dossier, with correctly categorised pumps, instruments and panels for the zone. This lets hazardous-area effluent be treated safely without compromising plant integrity.

Zone 1 Certified

Equipment rated for Zone 1 (high probability of explosive atmosphere) with Ex d flameproof or Ex e increased safety protection.

Zone 2 Rated

Equipment suitable for Zone 2 (low probability of explosive atmosphere) with Ex n or Ex p protection methods.

Full Compliance

Complete ATEX 2014/34/EU compliance with CE marking, EU Type Examination Certificates, and quality assurance.

Gas Groups

Equipment rated for IIA, IIB, and IIC gas groups covering methane, propane, ethylene, and hydrogen atmospheres.
