How it works
From Your Test Protocol to an Operational System
You define the experimental need
Your test protocol requires pressure, temperature, or fluid conditions that no standard equipment can meet.
We engineer, build, and qualify
Our engineering team designs the system. You approve the drawings before manufacturing in our workshop, then validate the Factory Acceptance Test (FAT).
You operate and get your data
The equipment is commissioned at your facility. We then provide maintenance, upgrades, and periodic requalification.
Industrial and Technical Centers
Develop and scale up a process, or qualify a material or instrument, with an automated rig designed for repeatability and safety.

Featured project
HPHT Reactors & Cells
Custom High-Pressure Rotating Reactor for Mechanochemistry at 250 bar
« How to seal and stabilize a multi-liter reactor that rotates under high pressure and temperature? »
For a public research lab in materials chemistry, IRIAN Mecatronics designed and built a high-pressure rotating reactor for mechanochemistry studies in supercritical CO2. This custom equipment performs ball milling operations at up to 250 bar (3,625 psi) and 100°C (212°F), ensuring a perfect seal during continuous rotation.
Equipment is not a product. We engineer and build a unique system for your protocol, then support it with the team that created it.

Design office and workshop, in Morlaàs
Who we are
Mechanical Engineering Team with an Integrated Workshop
In-house design and manufacturing
The mechanical, instrumentation, and automation systems for our equipment are designed, assembled, and tested in our workshop in Morlaàs.
An expertise born from maintenance
Founded in 1994, our culture of pressure equipment maintenance has forged a know-how in robust and reliable design.
Quality and regulatory compliance
We are ISO 9001 certified. Our equipment is designed according to the Pressure Equipment Directive (PED 2014/68/EU) and can be delivered ATEX-compliant.
Member of the IRIAN group
IRIAN Mecatronics is part of the IRIAN group, alongside its sister company Irian Technologies.
How does a project start?
It starts with a technical discussion with an engineer. You describe your experiment (fluid, conditions, measurements), we analyze its feasibility, and we send you a technical and commercial proposal.
My project is confidential. How do you protect it?
We can sign a Non-Disclosure Agreement (NDA) before any technical exchange. Your data, drawings, and your organization's name remain confidential and are never published without your explicit consent.
What is the lead time for a system?
It depends on the system's complexity and the procurement time for materials (e.g., special alloys). The schedule is detailed in our proposal and tracked at every stage.
Do you service equipment from other manufacturers?
Yes. We provide maintenance, retrofitting (automation, sensors), and periodic requalification for pressure equipment from all brands.
Do you ship internationally?
Yes, we deliver and commission our equipment worldwide. Documentation, training, and support are provided in both French and English.
Discuss Your Test Protocol
Describe your experimental needs: fluids, target pressure and temperature, required measurements. An engineer from our design office will contact you within 48 business hours to discuss technical feasibility.
