Capacitors & other Products
CELEM is a Contract Partner of Plustherm Point AG
Celem is the world's leading developer and producer of high power capacitors for induction heating and for wireless power transfer applications.

The extensive catalog of high power capacitors for induction heating, provides our customers with endless options of capacitance, voltages and currents. Celem's engineers and scientists have a vast experience in designing capacitor banks and we provide this knowledge free of charge to our customers.

More than 50 years ago Celem invented the conduction-cooled capacitor, later the well known CSM capacitor and other capacitors and assembly structures that are still the building blocks of the industry.
​
Celem's recent patented invention, the C-Cap capacitor is a breakthrough in the world of power capacitors, as it doubles the power density of previous power capacitors.

Conduction-Cooled capacitors were invented by CELEM, and are widley used in the industry today. They are very compact and have a high power/voume ratio. 
They are used, for example for:
  • inductive heating resonance circuits
  • medical imaging
  • heat treatment
  • plasma applications
  • wireless power transmission
  • electric vehicles
  • high frequency converter
Properties of the high-performance capacitors:
  • polypropylene-conduction-cooled
  • self-regenerating
  • small EST
  • small losses
  • ​UL94-V0 on request

CPRI 400 New
​Is a new 400kVAr capacitor.
CSP 305A
This type with 300kVAr used to be the prefered building block in many assemblies. Today the CSP 405A and CSP 305A/600 replaces it successfully.
CSP 305B
This type with 300kVAr used to be the prefered building block in many assemblies. Today the CSP 405B and CSP 305B/600 replaces it successfully.

C500T
Is CELEM's best-selling MF capacitor. With 500kVAr it is a great building block for high power systems.
C500Q
​Has the same height as the C500T. Due to its different capacitance element, it provides higher voltages than the C500T.
C700T
Has a the same height as the C500T. Due to its larger diameter it goes up to 85µF.
Water-cooled capacitors are very similar to CELEM's conduction-cooled capacitors, but they incorporate the water cooling inside the capacitor, thus ensuring optimal performance.
They are used, for example for:
  • inductive heating resonance circuits
  • medical imaging
  • heat treatment
  • plasma applications
  • wireless power transmission
  • electric vehicles
  • high frequency converter
Properties of the high-performance capacitors:
  • polypropylene-conduction-cooled
  • self-regenerating
  • small EST
  • small losses
  • ​UL94-V0 on request
