Electric Compressor (eCompressor)
Discover the eCompressor
A compressor is a device that compresses a gas, meaning it increases its pressure. In doing so, it provides energy to the gas in the form of pressure. An electric compressor is a compressor driven by an electric motor. There are two main categories: first, dynamic compressors, which convert the gas’s kinetic energy into pressure (centrifugal or axial compressors), and second, positive displacement compressors, which increase the gas pressure by reducing its volume (piston, screw, scroll, vane…).
The applications targeted by MMT are mainly in two areas:
- Mobility: Applications related to the chassis (commercial vehicle braking, automotive suspension, tire inflation, sensor cleaning for ADAS…) or gas recirculation for the hydrogen internal combustion engine.
- Medical: Oxygen concentrators, respiratory assistance systems for sleep apnea, and powering pneumatic instruments are examples of medical applications considered by MMT.
Of course, MMT remains open to all customers’ challenges!
REGENERATIVE COMPRESSORS
A regenerative compressor (preferentially called blower in case of low pressure) is a type of dynamic compressor designed to handle low-flow, high-pressure applications. Unlike centrifugal compressors, which rely on a single energy transfer, regenerative pumps use a specially shaped impeller with multiple vanes and a circular channel (called a “regenerative” or “peripheral” chamber) to repeatedly impart energy to the fluid as it circulates around the impeller.
How it works?
- The gas enters the compressor and is trapped between the impeller vanes and the compressor casing.
- As the impeller rotates, the fluid moves along the circular channel, gaining energy when the fluid is accelerated by a vane.
- This repeated energy transfer “regenerates” the pressure, allowing the compressor to achieve relatively high discharge pressures at low flow rates.
Compact design optimized for high-pressure, low-flow systems. Its pressure–flow performance offers an interesting compromise between what centrifugal and positive displacement technologies can achieve.
Bi-directional operation, allowing flexibility in system integration.
Through CFD analysis and global optimization (optimization of the wheel and optimization of the driving motor), MMT has successfully addressed the well-known challenge of efficiency, achieving values close to those of centrifugal compressors.
