Our Mastery of the constraints and requirements of the energy sector

Oil extraction

Fossil fuel industries, such as oil and gas extraction, use MERGER reducers and variable speed drives in various equipment, such as pumps and compressors, to adapt speed to specific process needs.

Your technical constraints

At MERGER, we design reducers de speed foroil extraction and gas who have to manage variable loads. We respond to your search for robustness and resistance.

We make sure to take your environments into account forage which can be difficult, with conditions such as the dust, vibes, and sometimes the presence of gas or liquids corrosive.

Nuclear

MERGER fixed ratio speed reducers are used in some nuclear energy applications, particularly to adjust the rotation speed of electrical generators.

Your technical constraints

Our speed reducers are used in your nuclear applications that must meet high safety standards. We know that the reliability and resistance (in French only) at radiation of our materials are important considerations for you.

Our speed reducers are designed to meet your environments nuclear which may be subject to specific conditions, such as constraints related to radiation and the procedures of security strict.

Hydroelectric

Hydroelectric power plants use MERGER speed multipliers to adjust the rotation speed of hydraulic turbines to maximize the energy efficiency of hydroelectric generation.

Your technical constraints

Our speed multipliers  are designed to handle highly variable loads depending on water flow rates. We also ensure that the resistance to the corrosion of our materials is important to guarantee an optimal lifespan for your equipment.

We take care to design equipment for the Central hydroelectric who resisthumidity and to variations of pressure.
