COBRA NC – The Robust and Flexible Solution for Demanding Applications

The COBRA NC is a series of high-performance and robust dry screw vacuum pumps for demanding applications with maximum flexibility and modularity for process changes. These vacuum generators are in use wherever gases and vapours 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. In practice this means no contamination of the pumped medium, and no environmental emissions. In addition, no costs arise for the purchase, replacement and disposal of operating fluids. Maintenance tasks such as oil changes or filter replacement are no longer required or are reduced to a minimum.

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 flavour. The high vapour 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:
 

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


Degassing of steel
The mechanical vacuum technology of the COBRA NC is ideal for high vapour/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 optimal solution for coating processes as key part of a vacuum system. Examples of applications are:
 

  • Plasma enhanced deposition
  • Physical vapour deposition
  • Chemical vapour deposition


Vapour recovery
The COBRA NC is the optimal vacuum pump for vapour 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
  • Vapour recovery during production processes

… and many more!
