Our story

From process equipment to complete control systems.

For more than 17 years, Petromarsh has brought British engineering to plants in the Gulf. We started by supplying process equipment to oil, gas and petrochemical operators. Today we also design, integrate and commission control systems for any industry that automates.

We exclusively represent three British manufacturers in the region: AMI Exchangers, Spiro-Gills Thermal Products and Young & Cunningham.

What we do

Five business lines, each with its own page.

01 Heat exchangersShell-and-tube and plate exchangers built in the UK by AMI Exchangers.
02 Air coolersForced-draft air coolers designed with HTRI and built by Spiro-Gills.
03 ValvesControl, isolation and relief valves from Young & Cunningham, with spares.
04 Control systems, instrumentation and powerDesign, integration and commissioning, from one panel to an HVDC platform.
05 ConsultancyC&I advice for any automated industry, and GCC market entry for European companies.

How we work

Every project follows the same seven stages.

Whichever line it falls under, we take each job from design to handover.
