The typical Renfert extra value is now available for preheating: Users fi nd their daily work signifi cantly easier, safer and yielding higher quality results and enjoy the long-term advantages of a secure investment.

We achieve this with the following philosophy:

  • and long service

  • For example, space for 4× size 6 plus 3× size 3 casting rings or 9× size 3 casting rings - ideal combustion area size
  • oven door with special ceramic fibres for holding casting rings

  • Max. heating speed to 900°C in 60 min.

  • fewer faulty castings, no time wasted with complex programming

Innovative ceramic base:
  • Molten wax is collected at the back of the oven at the extractor, not at the door (optimised outlet for combustion residues)

High-performance catalytic converter

The Magma has an ideal design with a catalyst converter that can be controlled at the oven:
  • Optimal ventilation of the furnace room
  • Catalytic post-combustion of furnace gasses (i.e. wax gasses)
  • Chemical transformation of organic constituents into carbon dioxide and steam
  • Unpleasant odours greatly reduced

And we save the best for last:
  • Renfert offers a three-year guarantee for the complete preheating oven!
  • The thermal sensor is the only exclusion.
  • This means: the guarantee even includes the heating elements (up to max. 6000 operating hours) - this must be unique in the world.
