What are the pressure and temperature limits of your reactors and autoclaves?

We do not have catalogue limits; we design the equipment based on the project's requirements. Our custom approach allows us to reach the conditions required by your test.

How do you ensure a reactor's resistance to highly corrosive fluids like H₂S or supercritical CO₂?

Material selection is a key step in our engineering process. Depending on the nature of the fluids, pressure, and temperature, our design office selects the most suitable alloys (Inconel, Hastelloy, Super Duplex, Titanium) and compatible seals. This expertise ensures the equipment's safety and service life, as well as non-contamination of the sample.

How are safety and PED compliance ensured for a custom autoclave?

All pressure equipment is designed in strict compliance with the European Pressure Equipment Directive (PED) 2014/68/EU. Our design office performs a systematic risk analysis, carries out sizing calculations (according to CODAP, ASME...), and compiles a complete manufacturer's data book. The equipment is then pressure-tested in our factory before delivery to guarantee its safety.

Is it possible to integrate specific features like visualization, stirring, or special measurements into a high-pressure cell?

Yes, integrating specific features is at the core of what we do. We design reactors to meet the protocol's needs: sapphire viewports for optical visualization, X-ray transparent walls for tomography, stirring via magnetic coupling, or volume control with a piston. Each feature is integrated while ensuring the entire assembly remains leak-proof and robust.

Custom High-Pressure Reactors, Autoclaves, and Cells

IRIAN Mecatronics designs and manufactures custom reactors, autoclaves, and cells for R&D and industrial applications. We develop equipment to conduct tests, including in corrosive environments or requiring in-situ visualization. Each system is a scientific instrument designed to address a specific experimental constraint, where off-the-shelf solutions fall short.

Running a test in a corrosive HP/HT environment

The corrosivity of fluids (H₂S, CO₂, brines) is magnified under high pressure and temperature. The design requires a critical selection of alloys (Inconel, Hastelloy...) and seals to guarantee the reactor's integrity, prevent sample contamination, and ensure test safety.

Observing or measuring a phenomenon through the pressure vessel

Visualizing a reaction or using external analysis methods (X-rays, spectroscopy) requires a radiation-transparent window. The challenge is to design this opening to withstand pressure and temperature without leaking or deforming, thereby ensuring reliable measurements.

Applying stress or varying volume under high pressure

Transmitting a force or displacement inside an already pressurized vessel requires leak-proof mechanical feedthroughs and powerful actuators. The system must provide precise control while compensating for the confining pressure, an essential requirement for PVT or geomechanical testing.

Adapting one system for multiple experimental protocols

Designing a single reactor for various operating modes (batch, flow-through...) is an integration challenge. This requires planning the fluid circuits and instrumentation for each mode, while ensuring a compact, safe, and easy-to-reconfigure design to guarantee the comparability of results.

Running an HPHT test on a very small sample volume

Reducing a reactor's volume (a few milliliters) concentrates mechanical and thermal stresses, requiring precise miniaturization of components (valves, sensors, seals). The design must ensure reliable measurements and safety while minimizing dead volumes to preserve precious or rare samples.
