Gulf plants run at 50 °C ambient, cool with warm seawater and often handle sour gas. We keep that in mind from the first calculation, not as an afterthought.
Design ambient up to 55 °C, seawater-grade metals, and fin fan coolers that cope with sand and dust.
You deal directly with the people who design and build your equipment, with no trading margin in between.
ASME U and U2 stamps, National Board registration, and ISO 9001, 14001 and 45001 at both factories.
Seaworthy packing and a complete set of export documents for any GCC port.
“When you send us a datasheet, an engineer reads it, not a sales script. Expect a few good questions before you get a price.”
