COBRA NC – The Flexible Solution for Industrial Vacuum Applications

COBRA NC are high-performance and robust dry screw vacuum pumps for demanding applications with maximum flexibility and modularity for process changes. They are in use wherever gases and vapors need to be pumped reliably.

The proven, completely dry screw vacuum technology allows the COBRA NC to run without operating fluids in the compression chamber.

Vacuum pumps of the COBRA NC series are the most advanced screw vacuum pumps on the market today. They operate efficiently throughout their vacuum range and deliver constantly high pumping speeds.

COBRA NC dry screw vacuum pumps feature a specially developed screw profile and unimpeded gas discharge. Their design ensures an even heat distribution over the whole pump stage, which results in reduced thermal stress and increased service life.

The screws are manufactured from a single-piece casting without any gaps. This makes the ingress of process fluids or particles impossible and thereby prevents corrosion.

COBRA NC screw vacuum pumps are available in a range of application-specific versions, including ATEX-certified versions. They can therefore be adjusted to suit any requirement.

COBRA NC Application Options

Applications

The robust and flexible solution for demanding applications

Vacuum distillation
COBRA NC vacuum pumps are ideal for vacuum distillation in various industries. Examples of COBRA NC in distillation processes:
 

  • Crude oil distillation – to separate out individual hydrocarbons
  • Solvent recovery – to recover solvents from a process medium
  • Vacuum-supported distillation – in pharmaceutical or chemical applications


Vacuum drying
Vacuum drying is used to dry items rapidly at low temperatures and without thermal damage. For example, it is employed in the drying of foodstuffs in order to preserve food flavor. The high vapor tolerance of COBRA NC vacuum pumps makes them ideal for drying processes with high humidity. Examples of applications are:
 

  • Freeze drying
  • Cleaning/Drying of industrial parts


Evacuation
The evacuation of vessels, such as the extraction of air or gas from closed vessels, is one of the most widespread applications of vacuum technology. These applications are consequently highly diverse. Common evacuation applications are:
 

  • Mold evacuation
  • Transfer chambers
  • Process chambers
  • Heat treatment
  • Space simulation


Steel degassing
The vacuum technology of the COBRA NC is ideal for high vapor/gas temperatures and elevated dust levels, as found in steel degassing processes. The energy efficiency of the COBRA NC is superior to all other technical solutions.
 


Forming, pressing and laminating
Forming, pressing and laminating with vacuum are important processes in many branches. Examples of applications are:
 

  • Thermoforming
  • Veneer pressing
  • Vacuum assisted resin transfer moulding (VRTM)
  • Flat panel display lamination
  • Solar panel lamination


Coating
Vacuum is a key part of many coating processes, creating specific atmospheric conditions to improve surfaces and component properties. COBRA NC screw vacuum pumps are the optimum solution for coating processes as key part of a vacuum system. Examples of applications are:
 

  • Plasma enhanced deposition
  • Physical vapor deposition
  • Chemical vapor deposition


Vapor recovery
The COBRA NC is the optimal vacuum pump for vapor recovery processes due to its innovative cooling system which ensures very low gas temperatures. Areas of usage are:
 

  • Storage tank systems
  • Rail tanker filling systems
  • Road tanker filling systems
  • Loading and unloading stations for tanker ships
  • Vapor recovery during production processes

… and many more!
