General description for types KM to TL:

  • Available in 5 sizes
  • Available with 3 different program controls
  • Heating elements on 4 sides. The temperature is equally distributed
  • High quality heating wire. The lower electric loading guarantees a longer service life
  • Heating elements covered with ceramic
  • A ceramic tray protects the heating muffle from becoming soiled
  • Stainless steel housing
  • Enamel coated housing, colour light grey (RAL 7035)
  • Door opens outwards with furnaces type KM•
  • Door opens sideways with furnaces types SL to TL. The heat is emitted towards the back
  • High quality insulating of firestone and fibre plates
  • Easy to attend because of the module execution
  • All furnaces are equipped with an exhaust pipe
  • Thermocouple for all types PtRh-Pt
  • Optional equipment: circulating air (type -U)
Optional equipment: circulating air (Type -U):

Furnace types KM to TL can be equipped with circulating air. The circulating air ensures an even distribution of the temperature to the casting muffle. The muffle centre temperature fits the programmed temperature more precisely.

A higher degree of accuracy is also attained; witch saves time in the following steps.

Furnaces with circulating air and program control unit P6 have been proven be particularly efficient for the use of casting titanium. 
 
 
4. Magma

Characteristics:
The versatile oven for reliable results. An oven is not just an oven, and Renfert has given the Magma some exciting new features. The typical Renfert extra value is now available for preheating:
Users find 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:
• Central element of the highest quality
• Concentration on useful functions
• Intelligent overall concept for optimum power
• and long service
• Unbeatable guarantee

Details:
Space:
• 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

Fast:
• Max. heating speed to 900°C in 60 min.
• special speed program available Accurate and reliable:
• Type S: Pt-RhPt temperature sensor
• four-sided heater/muffle chamber in one piece
• ideal temperature distribution in oven
• actual temperature at casting ring height shown
• controlled heating rate of 0-9°C per minute
• accurate, gentle and also fast heating available


Easy to use:
• no learning period required to operate oven
• symbols easily understood
• casting time input in real time (date and time)
• 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 (no flashover, no smoke in the laboratory
High-performance catalytic converter
The Magma has an ideal design with a catalyst converter that can be controlled at the oven:
• clean, healthy air in the laboratory
• no unpleasant odours

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.
