Energy

MERGER manufactures reducers, multipliers et speed variators for the sector ofEnergy for more than 70 years. We supply and repair, among other things, reducers used for polar bridges in industry nuclear en France et al'international. We manufacture, install and repair multipliers enabling the supply of electricity with power stations hydroelectric. We also produce reducers for your 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 reducers and speed variators MERGER in various equipment, such as pumps and compressors, to adapt the speed to the specific needs of the process.

Your Constraints

At MERGER, we design reducers de speed foroil extraction and gas in order to manage variable loads. We respond to your search for robustness and resistance. We make sure to take into account your environments. forage difficult, with conditions such as the dust, vibes, and the presence of gas or liquids corrosive.

Nuclear

Speed ​​reducers MERGER are used in some nuclear energy related applications, largely for the lifting nuclear loads (PMC: fuel handling station) and equipment handling (overhead cranes).

Your Constraints

Our speed reducers are used in your applications nuclear who must respond to safety standards high. We know that the reliability and resistance of our materials are essential considerations for you.

Our speed reducers are designed to meet the environments nuclear subject to specific conditions, such as extended lifespans and security procedures strict.

Hydroelectric

Power plants hydroelectric use MERGER speed multipliers to produce electricity from renewable resources.

Your Constraints

Our speed multipliers are designed to handle charges very variable depending on the water flow rates. We also provide resistance to the corrosion of our materials to guarantee you a optimal lifespan of your equipment. We ensure the design of hydroelectric power plant equipment for a continuous operation during periods of high demand. Our devices are robust and et recognized on the market.
