Zone 1 and Zone 2 diesel generators
Explosion-protected diesel engine, alternator, controls, starting system, instrumentation and auxiliaries.
ApplicationsPrimary, standby and emergency offshore power
One SunEx. Two engineering centres.
European certification and R&D capability, paired with responsive Southeast Asia execution.
SunEx develops explosion-protected components, equipment and integrated packages for hazardous-area applications. Our capabilities combine product design, certification knowledge, electrical and controls engineering, package integration, manufacturing coordination, testing and regional service.
SunEx Technology Europa S.r.l. was established in 2019 near Milan and is the group headquarters, ATEX certificate owner and European R&D and certification centre. SunEx Tech Asia Pte Ltd in Singapore is the regional engineering and project-execution hub, and the interface for EPC contractors, operators, consultants and technology partners across Southeast Asia.

Engineering disciplines
Certification of individual components does not by itself establish suitability of the complete package. SunEx manages the system interfaces, application conditions and conformity route.
- Hazardous-area electrical engineering and Ex equipment selection
- Mechanical package integration and environmental design
- Control, instrumentation, PLC and generator-management systems
- Fire and gas detection, ventilation, pressurisation and shutdown concepts
- Quality planning, inspection, FAT and documentation management
- Commissioning, operator training, spares and after-sales support

ATEX certification
A broad certified component platform
SunEx Technology Europa S.r.l. is the referenced certificate owner and ATEX quality-system centre, holding 24 certified product families plus the Annex IV quality-assurance notification, across engines, rotating machines, enclosures, lighting and intrinsically safe instrumentation.
Selected ATEX certification documentation carries TUV NORD Cyprus monitored-production marking under Directive 2014/34/EU. Certification applies only to the approved products, variants and certificate conditions identified in the current technical file.
Final package conformity depends on approved certificate variants, equipment marking, integration, operating conditions, technical documentation, quality controls and the applicable project assessment route. Current certificate revisions and approved variants must be checked before application.
