Energy
MERGER has been manufacturing gearboxes, speed multipliers , and variable speed drives for the energy sector for over 70 years . We supply and repair, among other things, gearboxes used for polar couplings in the nuclear industry in France and internationally . We manufacture, install, and repair gearboxes for power generation from hydroelectric plants. We also produce gearboxes to facilitate oil extraction and refining.
Our Mastery of the constraints and requirements of the energy sector
Oil extraction
Fossil fuel industries, such as oil and gas extraction, use MERGER speed reducers and variators in various equipment, such as pumps and compressors, to adapt the speed to the specific needs of the process.
Your Constraints
Nuclear Energy
MERGER speed reducers are used in certain nuclear energy applications, largely for lifting nuclear loads (PMC: fuel handling station) and handling equipment ( overhead cranes ).
Your Constraints
Our speed reducers are used in your nuclear applications , which must meet high safety standards . We know that the reliability and strength of our materials are essential considerations for you.
Our speed reducers are designed to meet the specific requirements of nuclear environments , such as extended service life and strict safety procedures .
Hydroelectric
Hydroelectric power plants use MERGER speed multipliers to generate electricity from renewable resources.
Your Constraints
