- Why choose us
Why choose us: a single point of contact, from design to service
The real question is not who costs less on a quote, but who answers when the room doesn’t hold its class. With the supply chain in-house, that answer has a single address, and it arrives with the drawing in hand.
- One contract instead of six supplies to be made to fit together at your own risk.
- Whoever designs and whoever produces work in the same place and talk to each other in front of the part.
- A single file from DQ to maintenance, consistent for an inspector.
- Whoever built it and whoever comes back for maintenance: not two different companies.
- 1technical contact
- 6phases under the same contract
- 0subcontracts on critical components

For those with a process that cannot stop
The advantage of an integrated supplier is not measured on a quote: it is measured the first time something doesn’t add up.
Four things that decide a cleanroom project
They are also the four points on which any offer should be compared, ours included.
- 01Supply chain
Direct production
We build the critical components ourselves. That means our own specification, our own quality control, spare parts available even in eight years and no supply chain to rebuild when a part is needed.
Control · Spare parts - 02Design
Verification before the site
Three-dimensional model, flow simulation, thermal load calculation. Good design is not visible: what you see is its absence, in the form of changes during construction.
3D model · CFD - 03Documents
A consistent file
From DQ to maintenance reports, a single documentation system. An inspector who opens the file finds a continuous story, not six different formats to reconcile.
ALCOA+ · Traceability - 04After
Whoever builds also services
Service is done by whoever installed the room. The difference is felt at the first intervention: no diagnosis from scratch, no passing the buck over who is responsible.
Service · Continuity
Six costs that don’t appear in the quote
The multi-supplier model seems cheaper as long as you only look at the written items. These six come later.
-
The cost of interfaces
Six suppliers generate fifteen relationships to manage, and every relationship is a point where responsibility can slip away. Coordination is not free: the client pays for it in meeting hours and calendar days.
-
The delay that belongs to no one
The panel arrives late because the installer hadn’t finished, and the installer was waiting for the drawing. With a single contract the delay remains a problem for whoever signed the date, not a three-way discussion.
-
The change during construction
The most frequent extra-cost item almost always comes from a regulatory requirement that came in late. If the standard enters in the first phase rather than at testing, that change doesn’t exist.
-
The file to be reassembled
Six suppliers deliver six sets of documentation with six different logics. Putting them back in order for an audit takes time, and meanwhile the inspection looks at the gaps between one document and another.
-
The unobtainable spare part
In five years the supplier of that hood may no longer make it. If the component is ours, the drawing is in the archive and the part is remade: it is the reason we keep production in-house.
-
Diagnosis from scratch
Whoever didn’t build the room, when there is a problem, starts by measuring. Whoever built it opens the file, looks at the right spot and knows where to intervene.
The four questions to ask anyone, us included
Who produces the critical components, and what happens in eight years if a spare is needed. Who signs the classification result, and with what calibrated instrumentation. Who writes the file, and in what format it is delivered. Who comes for maintenance, and in what time frame.
These are four uncomfortable questions to which an integrated supplier answers with a single name, four times. If the answers are four different names, coordinating them is a job, and someone will do that job: probably you.
- Who producesand who supplies the spare parts
- Who certifiesand with what calibration
- Who servicesand in what time frame
Six steps, a single point of contact
It is the path we follow on every project, and the most honest way to show what you are buying: what is looked at changes at each step, not who answers.
-
01
Analyze
Process, standards and site constraints: from these come the class and the URS that defines it.
-
02
Design
Layout, separate flows, pressure cascade and HVAC, verified on BIM and CFD models.
-
03
Manufacture
Panels, metalwork and control boards in our workshop, with factory acceptance testing (FAT).
-
04
Install
On-site assembly, systems and monitoring, on-site verification (SAT) and start-up.
-
05
Qualify
We carry out the tests and deliver audit-ready documentation, where required.
-
06
Support
Scheduled maintenance, filters and calibration, even on other makers’ systems.
Where this way of working makes a difference
In every sector, but for different reasons: here the file matters, there the downtime, elsewhere the repeatability of the class.

What being compliant means for us
Being compliant doesn’t mean having the longest list: it means citing the right edition and knowing how to apply it to your case.

Questions about comparing suppliers
The questions that come up on every site visit, with the answer we would give in person.
Does an integrated supplier cost more?
On a quote it may seem so, because the offer includes items that in the multi-supplier model are left out: coordination, site management, documentation, final tests. On the final account the comparison changes, because those items don’t disappear: they just change pockets.
What happens if the project changes along the way?
The model is redone, the impact on flows and pressures is checked and the schedule is updated. Since everything is within the same contractual perimeter, the change doesn’t require renegotiating six supplies: it is the reason why changes along the way cost less.
Are you tied to specific components? Can we use our own suppliers?
Yes, if they have the characteristics required by the project. It often happens with air handling units or with supervision systems, where the client already has a plant standard. What we ask is to be able to qualify them, because we are responsible for the final result.
How do you guarantee spare parts over time?
The components we produce have the drawing in the archive: they can be remade even years later, even if the model has changed in the meantime. For purchased components we keep the specification, which allows replacing with a qualified equivalent rather than whatever turns up.
Do you also work on parts of a project?
Yes. Not all projects make sense turnkey: sometimes only qualification is needed, sometimes only the supply of isolators or filter units, sometimes only the service contract. The integrated model is an offer, not a condition.
What guarantees do you give on the classification result?
The design class is demonstrated with the field tests required by ISO 14644-3 before delivery. If the room doesn’t reach it, the problem is ours until it does: it is the direct consequence of having signed the design as well.
Compare us too
Bring the specification you have: in a site visit it becomes clear which items are comparable between two offers and which are not.
