Hermetically sealed compressors

Discover new frontiers for gas compression in exploration and transport

Hermetically sealed compressors play a crucial role in industrial applications, subsea exploration, and gas transport due to their reliability, efficiency, and ability to operate in harsh environments.

For subsea applications, hermetically sealed compressors such as the HOFIM® compressor from Everllence (former MAN Energy Solutions) are designed to withstand high pressures, corrosive environments, and extreme temperatures. Our compressors help optimize gas recovery at the wellhead, improving efficiency while reducing greenhouse gas emissions.

Hermetic compressors also ensure continuous, reliable gas flow with minimal downtime in gas pipeline systems. Our MOPICO® compressor, for example, is a motor-driven, hermetically sealed unit designed for pipeline compression, offering low maintenance and high efficiency. These compressors eliminate the need for gearboxes, couplings, and lubrication systems, making them ideal for long-distance gas transport while reducing operational costs.

A fully sealed compressor which pushes the boundaries

Our High-Speed Oil-Free Integrated Motor compressor (HOFIM®) boosts oil and gas recovery while cutting emissions. Combining proven tech with innovation, it’s ideal for pipelines, storage, export, and subsea use. With no dry gas seals, lube oil system, or gearbox, it requires minimal maintenance. Featuring a high-speed motor and magnetic bearings, it runs quietly, needs no warm-up, and supports unlimited starts. Also suited for LNG, hydrogen, and CO₂.

Typical performance data:

  • Compression power up to 18,000 kW (24,000 HP)
  • Discharge pressure up to 303 bar (4,395 psi)
How you benefit:
  • Emission-free, environmentally friendly system 
  • Small footprint and low weight
  • Extended operating range due to magnetic bearing and the choice of parallel/series operations
  • Ideal for remote control and unmanned operation

MOPICO® – say hello to cutting-edge pipeline compression

The MOPICO® motor-driven compressor offers outstanding reliability with minimal maintenance, reducing downtime and ensuring continuous gas transport. Its hermetic design features a single rotating element, magnetic bearings, and no couplings, gearbox, lube oil, or shaft seals. This simplicity results in low capital, operating, and maintenance costs. Like the HOFIM®, it supports unlimited starts and runs quietly.

Typical performance data:

  • Compression power up to 18,000 kW (24,000 HP)
  • Discharge pressure up to 150 bar (2200 psi)
  • Inlet flow up to 30,000 m3/h (17,650 cfm)
How you benefit:
  • Emission-free, environmentally friendly system 
  • Small footprint and low weight
  • Extended operating range due to magnetic bearing and the choice of parallel/series operations
  • Ideal for remote control and unmanned operation

Hermetically sealed compressors FAQs

A hermetically sealed compressor integrates the motor and compression unit within a single airtight casing, eliminating the need for external seals, couplings, and lubrication systems. As a self-contained unit, the motor directly drives the compressor, simplifying operation and reducing maintenance.

It works by drawing in gas via a suction line. The gas then enters the compressor shell, where it circulates around the motor for cooling before reaching the compression chamber. As pressure increases, the gas is discharged for transport or further processing.

Hermetic compressors feature a compact design, making them ideal for space-constrained applications like offshore platforms. Their exceptional reliability and low maintenance requirements are critical for remote or hard-to-access locations, where servicing and maintenance is challenging. Optimized for harsh environments, they withstand extreme conditions while ensuring efficient performance. By eliminating the need for gearboxes, couplings, and lubrication systems, hermetically sealed compressors reduce operational costs. Additionally, their low-vibration, quiet operation improves stability, further enhancing system efficiency.
