ADR designs and manufactures a wide range of precision ball bearings that meet the most demanding technical specifications in order to provide innovative solutions in the mechanisms of various fields, such as Chemistry, Nuclear, Oil & Gas, Vacuum, etc.

The materials, liquid or solid lubricants and manufacturing processes are qualified and field proven. The range of bearings is extensive: from 1 to 330 mm. ADR selects the most appropriate materials, such as stainless steels, ceramics, superalloys, etc., at the design stage.

These solutions guarantee reliability, strength and longevity in aggressive environments.

ALSEAMAR uses innovative surface drones and subsea gliders for independent observation of the marine environment.

These turnkey services are used to collect and analyze data for a wide range of missions: scientific research, oceanography, marine environment protection, water quality monitoring, recording of ambient noise, intervention for hydrocarbon leaks, detection of natural gas or oil leaks, baseline studies and metocean operations for oil operators.

The SeaExplorer subsea glider is a detection platform perfectly suited to these operations. A high-endurance, autonomous subsea drone, it was designed to collect data over large areas (thousands of kilometres), over long periods (months) and at great depths (1,000 m) thanks to the integration of a wide range of specific sensors.

Controlled from land, propelled by variations in buoyancy, the vehicle glides silently along the water column collecting physical, chemical, biological and/or acoustic data, depending on the mission assigned.

The added value of the SeaExplorer lies in the low operation cost compared to the vessels or other means traditionally mobilized for the same type of mission.

ATMOSTAT designs and manufactures a line of high-performance heat exchangers consisting of superimposed pre-machined plates providing channel geometries dedicated to each application. Assembly of these individual plates calls for metallic bonds produced by a diffusion welding technique assisted by Hot Isostatic Pressing (HIP).

This technology, which involves high pressures and temperatures on the parts to be assembled, allows for welding at the heart of the material, not just on the surface. It enables the plates to be welded consistently with no added material, an operation that is impossible using more traditional techniques.

CHAMPALLE designs and manufactures equipment for glove boxes, incorporating high availability instrumentation and control, automation and robotization.

On new installations or dismantling projects, CHAMPALLE intervenes for process and equipment nuclearization missions for contaminating environments, on maintainable and decontaminable mechanical and electromechanical systems and processes (conveying, handling, machining, characterization, etc.).
