Specific benches for your needs

To develop a specific bench adapted to your needs, we mobilize our skills in mechatronics, combining mechanics, electronics and software. Our expertise extends to crucial areas such as structural calculation, vibration modes and simulation, forming the basis of our technical approach.

The Emitech Group's experience feedback in motorization, electrification and environmental constraints offers you a unique advantage in the automotive sector. We have specific expertise in thermal, hybrid and electric powertrains, as well as in innovative energies such as hydrogen (H2), ammonia (NH3) and e-fuels.

Our know-how also extends to fields such as hydraulics, regulation, advanced mechanics, electronics and electrical machines.

Throughout the process of creating your test bench, our project managers work closely with you.

Our pre-study includes a risk analysis, technical discussions with you and our suppliers, the establishment of a costing and the submission of our technical and financial offer.

Our aim is to secure the entire project for a balanced relationship of trust covering the quality of deliverables, deadlines and costs.

Project-based management for continuous quality control, deadlines and costs

As soon as you accept our offer, you will be assigned a dedicated project manager who will coordinate all the parties involved.

Weekly communication is set up to review progress and address points related to design, human machine interface (HMI), planning, procurement deadlines, lists of actions to be carried out in the coming weeks.

A fortnightly steering committee produces a progress summary, keeps the project dashboard and project risk analysis up to date.

Support, maintenance and after-sales service

We stand by our customers and provide long-term support for our benches and installations.
We support you throughout the entire lifecycle of your products, providing maintenance but also enabling you to upgrade or retrofit them.

Our maintenance services can be both preventive and curative.

Preventive maintenance

You retain the characteristics and performance of your test equipment

Maintenance of original technical specifications
Advice for optimum use
Free telephone support

Curative maintenance

You remedy breakdowns, failures and malfunctions of your means

Pre-diagnosis of the breakdown
Intervention of an expert technician within the contractual timeframe
Permanent stock of critical parts according to the contract

We offer a level of maintenance adapted to your use. The frequency and duration of our interventions are defined beforehand and commit us to the availability rate of your equipment. We draw up a maintenance register and issue you with a verification report referring to the requirements of ISO 17025

Transformation of existing benches, retrofits...

Our teams are able to upgrade the benches present in your facilities.

Our retex is particularly important for work carried out on our own installations to operate our traditional ICE engine test beds with synthetic fuels (e-fuel) or even to modify them more thoroughly for operation with the addition of H₂ and NH₃.

Examples of elements to integrate for retrofitting an ICE e-fuel dyno

Adjustments in the fuel supply system and injectors for e-fuel devices
Modifications in emissions measurement systems to accurately assess NOx, CO2, particulates, etc.
Adjustment of combustion parameters such as air/fuel ratio, temperature and pressure, adapted to e-fuel characteristics.

Example of the transformation of an ICE bench into an ICE H2/NH3
