The COBRA BC 0600 F Premium Efficiency is a dry screw vacuum pump in the proven COBRA BC series. State-of-the-art screw vacuum pump technology featuring a specially developed screw profile sets new standards of efficiency, making these vacuum pumps the ideal solution for tasks in load lock and transfer chambers, as well as in processes such as metrology, lithography, physical vapour deposition (PVD) and rapid thermal annealing (RTA).

The COBRA BC Premium Efficiency series equipped with the latest Busch VacBoost technology meets today’s demand for maximum energy savings and environmental sustainability through 40% lower energy consumption compared to standard vacuum generators. An intelligent stand-by mode, along with a wide range of flexible idle modes, offers additional energy savings potential. High reliability and minimal maintenance further reduce total cost of ownership.

Due to the sophisticated bell shaped cantilever construction, the twin rotor with Screw Vacuum Pump BC 0600 F Premium Efficiency COBRA variable pitch screws is mounted only on the motor side, while the unique “flying bearing” design makes inlet bearings unnecessary. As a result, the pumped medium does not come in contact with the bearings. This ensures clean vacuum generation and allows the full recovery of pumped gases. The direct gas path between inlet and outlet prevents dead spaces and ensures there are no process deposits inside the compression chamber.

The patented self-balancing screw design and screw rotor mounted precisely at the centre of gravity ensure excellent running qualities and guarantee high uptime. A directly mounted canned motor makes the dimensions of the COBRA BC series very compact.

The fully open communication protocol (Modbus TCP-IP) allows control of all functionalities, including idle modes. It can easily be adapted to a specific network protocol using standard interface components.

Technical specifications
The COBRA BC 0600 F Premium Efficiency is a screw vacuum pump combined with one vacuum booster. Two screw rotors inside the cylinder of the screw vacuum pump rotate in opposite directions. The pumped medium is trapped between the cylinder and screw chambers, compressed, and transported to the gas outlet. During the compression process the screw rotors do not come into contact with each other or the cylinder. Thus, no lubricants or operating fluids are required in the compression chamber. The advanced screw design results in lower electrical energy consumption and a lower compressed gas heat load compared to standard screw designs. COBRA BC series vacuum pumps use efficient direct water cooling resulting in an even temperature distribution throughout the pump body, and guaranteeing thermal stability throughout the process. The COBRA BC 0600 F Premium Efficiency uses a high-performance vacuum booster to optimize the system performance.
