Evidence over assertion
Every rating we publish is traceable to a witnessed test on our own rigs. If we cannot measure it, we do not claim it.

The story
We built the laboratory before we built the sales team.
In 2012, six years into the business, we spent more than a year's profit on an integrity test laboratory. It was not an obvious commercial decision. Our competitors were sending elements to third-party labs and waiting weeks for a certificate.
What it bought us was the ability to say a number and mean it. A beta ratio measured on our own multipass rig, an aerosol carryover figure from our own ISO 12500 bench, a scan test on the specific HEPA element leaving the building — not a population average, not a supplier's claim.
Everything since has followed the same pattern. The CFD group exists because we were tired of discovering flow maldistribution at commissioning. The cleanroom exists because pharmaceutical clients needed validation evidence, not assurances. The second campus exists because a 61-tonne separator will not fit through the door of the first one.
Nineteen years on, we are a filtration engineering company that happens to have excellent fabrication, rather than a fabricator that also sells filters. The distinction shows up in every quotation we send.
Vision
A world where every industrial process runs on clean streams — where separation is no longer the weak link between ambition and output.
Mission
To engineer filtration systems that hold their rating on the ten-thousandth cycle, and to hand every client the data that proves it.
Quality policy
Worldasatech maintains a quality management system that treats every filtration element as a pressure-retaining, life-safety component. We qualify raw material at receipt, hold weld procedures to ASME IX with in-house requalification every six months, and release no system without a signed, retrievable data book covering material traceability, hydrostatic proof, integrity verification and dimensional conformance.
Timeline
Nineteen years, eight decisions that mattered.
- 2006
Founded as a housing fabrication shop
Three engineers, one rolling machine, and a contract to build basket strainers for a regional chemicals plant.
- 2009
First ASME U-stamp vessel
Certification opened the door to hydrocarbon service and moved the company from parts supplier to system builder.
- 2012
Integrity test laboratory commissioned
In-house bubble-point, diffusion and multipass rigs ended reliance on third-party validation and cut lead times by weeks.
- 2015
Automated self-cleaning platform launched
The AXIS series introduced differential-pressure-triggered backwash to clients running high-solids cooling loops.
- 2018
Gas coalescing division established
Dedicated engineering for natural gas, instrument air and compressor protection, validated to ISO 12500.
- 2021
Second campus and CFD group
A 14,000 m² facility with computational fluid dynamics in-house, letting us model vessel internals before steel is cut.
- 2023
Pharmaceutical cleanroom line
Class 8 assembly and validation for sterilising-grade cartridges, released with full extractables documentation.
- 2026
Hydrogen and semiconductor programmes
Ultra-high-purity separation for electrolyser feed loops and sub-fab abatement, now in qualification with three global OEMs.
Values
Six principles, written the way we actually apply them.
These are operating rules, not aspirations. Each one has cost us money at least once, which is how we know they are real.
Design for the tenth year
Housings are sized for the fatigue cycle, not the datasheet. We engineer for the decade a plant actually runs, not the day it starts.
Metallurgy is a decision
Alloy selection is treated as an engineering discipline — chloride load, temperature, and duty cycle drive the choice, never habit.
Answer fast, then answer well
A process engineer stuck on a line needs a number today. We resolve first, document second, and never invert the order.
Own the commissioning
Our responsibility ends when the differential pressure curve settles on site — not when the crate leaves the gate.
Build people, not headcount
Welders, designers and validation engineers are trained in-house against internal qualifications above the code minimum.
Why Worldasatech
Six reasons process engineers
keep the number.
None of these are differentiators on a brochure. They are the things that decide whether a filtration system still works in year seven.
01
We size it before we sell it
Every quotation carries the calculation behind it — flow, velocity, pressure budget and turndown. If the numbers say our product is wrong for your duty, the quotation says so too.
02
Design and fabrication share a floor
The engineer who drew it can walk to the bay where it is being built. Constructability problems are solved in hours instead of through revision cycles.
03
Our own laboratory, not a subcontractor's
Multipass efficiency, aerosol carryover and integrity testing run on rigs we own. Validation is measured in days, not scheduled around someone else's queue.
04
One named engineer, start to finish
The same person owns your project from enquiry through commissioning, and remains reachable afterwards. There is no handover point where knowledge evaporates.
05
Documentation built for audit
Data books are indexed, traceable and delivered at dispatch — not assembled retrospectively when an inspector asks for them.
06
We service what others supplied
Relationships frequently start with an independent assessment of somebody else's installation. We will tell you if it is fine.

Work with us
Start with a conversation, not a purchase order.
Most of our long-standing clients began with a question about somebody else's equipment. We are comfortable with that.
