About ITSB

The filtration & separation authority for Asia-Pacific oil & gas.

We remove what others miss.

The engineers behind the authority — 30 years of designing, fabricating, installing and commissioning separation systems in-region.

The story

Thirty years, three beats

1993

Founded, Malaysia

An independent engineering firm built around one conviction: the region's plants deserve separation engineered for the duty — not parts shipped from a catalogue.

The partnership

Genuine Pentair, in-region

Genuine Pentair Oil & Gas Separations technology, in-region — the published performance of the world's best separation technology, engineered and backed on the ground.

Today

The region’s separation & filtration engineering arm

The engineering arm of the Process Materials group — head office Malaysia, offices Australia and Indonesia, Pentair reach across Asia-Pacific.

What makes us different

The whole system, in-house

Design Fabrication Installation Commissioning

Every stage is ours, so every result is ours. We solve the application, not just supply the part — the difference between a filter that fits the flange and a system that holds spec for years.

Why it holds

Three pillars

01 / THE ENGINEERS

30 years on the ground

Design → fabrication → installation → commissioning in-house. Senior engineers who own the outcome, from spec to start-up.

02 / THE REACH

In-region, on your site

Head office Malaysia, offices Australia and Indonesia — Pentair reach across Asia-Pacific.

03 / THE TECHNOLOGY

Genuine Pentair, published performance

>99.99% separation to 0.1 micron, ~99.98% hydrocarbon recovery — figures Pentair publishes, and we commission.

ISO 9001 · LRQA / UKAS DESIGN → FABRICATION → INSTALLATION → COMMISSIONING, IN-HOUSE

30 years delivering separation and filtration work for PETRONAS-group operations.
