Rely on Excellence
The RoTechBooster

The robust RoTechBooster design leads to unparalleled performance and reliability. It gives operators an unequivocal advantage not only compared to conventional piston boosters, but also to other rotating systems available in the market.

Seal gas booster technology

Centrifugal design for excellent results.

The EagleBurgmann RoTechBooster sets a high operational efficiency standard, leaving traditional seal gas booster solutions far behind.

A key feature is the unique rotating design in combination with the high efficiency magnetic coupling. The magnetically coupled drive keeps everything 100% hermetically sealed. This eliminates emissions and increases safety for the personnel. The high efficiency pressure barrier is maintenance free and leading-edge technology delivering extremely low eddy current losses. The state-of-the-art impeller design handles a wide range of operating pressures as well as varying gas density worry free.

The third plus is the directly coupled standard electrical motor and bypassing pressure reduction elements. This minimizes required horsepower and ensures lower capital investment.

RoTechBooster advantages in brief:

  • Proven technology
  • Simple set-up and easy operation
  • Virtually wear free operation 
  • Enables low pressure start permissive
  • Minimum maintenance efforts 
  • Energy efficient technology
  • Environmentally friendly solution

Rotating design benefits

Excels where piston boosters fall short.

For decades, air-driven piston boosters have been the imposed decision. Unfortunately, many users have experienced poor reliability, especially when requiring long periods of operation. The need for seal gas flow beyond the design’s ability, has also contributed to their poor performance. 

The air driven systems are complex, not only for the booster itself but for the controls to ensure its operation, over pressure protection and seal wear monitoring. With their many moving parts and high utility requirements, these maintenance-intensive systems are a very uneconomical choice.

Piston type booster flow capabilities are often below minimum flow requirements. Two or more of these units are required to achieve the minimum process labyrinth velocity. The choice is then to accept lower than recommended velocities or a higher air consumption and cost associated with multiple units.

An application-oriented comparison illustrates the RoTechBooster cost advantages over an air-driven piston booster.
