Engineering services
Your high-speed turbomachinery development partner.
MITIS is a team of turbomachinery engineers in Liège, Belgium, that designs, builds and tests oil-free machines running above 100,000 rpm. We help OEMs and industrial companies develop compressors, turbines, expanders, combustors and complete systems, from a first feasibility study to a tested prototype ready for industrialization.

Why MITIS
Why industrial companies work with us
Proven on our own machines
Every technology we offer runs in our own products, such as the M10 micro gas turbine. You benefit from hardware experience, not only simulations.
Design, build and test under one roof
Simulation, design, manufacturing follow-up and instrumented testing happen in the same team, which shortens iterations and reduces risk.
A senior, agile team
A compact team of PhDs and experienced engineers, fast to start, flexible on scope, and used to working alongside large engineering departments.
Confidential and industrial
NDA-based collaboration, intellectual property arrangements adapted to each project, ISO 9001:2015 processes and APQP-based industrialization.
Engagement models

A short, fixed-scope study to assess a concept: cycle, sizing, architecture and risks.
Component development
A bearing, combustor, rotor or heat exchanger designed and tested to your specification.
Prototype development
A complete high-speed machine or system, from concept to tested prototype, ready for industrialization.
Test campaigns
Instrumented tests on our rigs to validate your components under representative conditions.
Technology licensing
Access to proven MITIS technologies to accelerate your own product development.

How we work
Four stages, one engineering chain
-
01
Conceptualization & Cycle Design
MITIS performs front-end engineering and system design, including feasibility analysis, thermodynamic architecture selection, and performance definition. Multiple cycle configurations and integration constraints are evaluated to identify optimal solutions. The resulting concepts integrate turbomachinery, thermal management, and auxiliaries into scalable systems aligned with industrial requirements.

02
Detailed Engineering
MITIS delivers multi-physics engineering design covering mechanical, thermal, fluid, electrical, and system-level development. Advanced modelling, simulation, and CAD tools are combined with practical know-how to design and optimize complex systems. This approach ensures high performance, reliability, and manufacturability from component to full system level.
-
03
Prototype Testing
MITIS provides instrumented manufacturing and experimental validation supported by LabVIEW-based data acquisition systems. This enables precise measurement, real-time monitoring, and reliable performance validation under representative conditions. The approach ensures accurate system characterization and verification against design targets.
-
04
Industrialization
MITIS applies a structured design-for-manufacturing approach supported by APQP methodology and ISO 9001:2015 processes. The focus is on manufacturability, cost optimization, and supply chain readiness from early design stages. Robust quality and validation processes ensure reliable and repeatable industrial production.
Reference Projects
Selected projects illustrating MITIS engineering capabilities
MITIS supports customers and partners through the full engineering chain, from concept development and system design to validation and industrial deployment. The following reference projects illustrate typical applications of our expertise.
Compressed Air Turbine
MITIS developed a 10 kWe compressed-air turbine for electricity generation from stored air, based on high-speed turbomachinery and gas foil bearings. The oil-free system enables high rotational speeds, low maintenance, and compact design. Fully instrumented, it allows detailed performance validation and scalability for decentralized applications.
Cryogenic Compander for BOG handling
MITIS developed a cryogenic compander for boil-off gas handling, integrating a high-speed compressor and expander on a single shaft with magnetic bearings. The oil-free system ensures precise control and high reliability. Operating with nitrogen down to −180 °C, it is ATEX-compliant and designed for demanding cryogenic environments.
Integrated PEM Fuel Cell for UPS
MITIS developed a hydrogen-based backup power system combining a PEM fuel cell, batteries, and a commercial UPS. The project included full system integration, power electronics, and safety systems. An advanced EMS ensures optimal coordination, enabling extended backup duration and high reliability for critical applications.
Bioethanol Flameless Combustor for Range Extender
MITIS adapted its flameless combustor for liquid fuels through the development of a dedicated atomization system, focusing on bioethanol. Designed for microturbine range extenders, the solution ensures stable mixing, low emissions, and reliable operation across a wide load range, supporting low-carbon mobility applications.
