Available furnace architectures:

 

 

6 pulse frequency converter, plus a capacitor bank, two power switches and two furnace bodies. One furnace body is in service, other one is in standby.

 


 

 

12 pulse frequency converter, plus a capacitor bank, two power switches and two furnace bodies. One furnace body is in service, other one is in standby.


 

"Hold-Melt" system. Two Frequency converters connected to two furnace bodies through separate capacitor banks and separate power switches

One furnace body is melting and the other one is sintering or holding the molten material.

 Portable Melting Furnaces

  • No need for new constructions or foundation
  • Can be used everywhere, feeding from the mains or a generator
  • Lower electricity costs due to higher efficiency, specific design and minimum path loss
  • All components installed on a portable chassis
  • Single day installation and commissioning
  • Feasible for smaller workshops with lower ceilings
  • Intelligent and centralized PLC and monitoring system for the furnace and cooling tower
  • Lower melting time compared to similar furnaces
  • Stainless steel furnace bodies
  • Rectangular cross section copper coil, with a minimum of 5 mm thickness, results in increased efficiency, and provides more safety in case of melt leakage
