FURNACE ELEMENTS

OPEN SPIRAL & STRIP ELEMENTS

Iron-chromium-aluminium (FECRAL) and nickel-chromium (NiCr categorize resistance-heating elements. The difference in crystal structure, mechanical, electrical and thermal properties allow these alloys to be formed into spiral or strip elements and can be applied to a wide range of heating applications at low or high temperatures.

 

IRON CHROMIUM (FECRAL)
This alloy can be formed into spiral or strip elements to suit the specific application where wire temperatures up to 1 400° C is required.

APPLICATIONS

  • High temperature furnaces in the heat treating, ceramic, glass or steel industries and many other applications

 

NICKEL CHROMIUM (NICR)
This alloy can be formed into spiral or strip elements to suit the specific application where wire temperatures up to 1 400° C is required.

APPLICATIONS

  • Heavy duty heating applications
  • More resistant to hazardous environments
  • Nonferrous metal melting

 

CANDLE ELEMENTS & ASSEMBLES

Electrical candle elements are designed to give a long life while operating at maximum power with rating up to 40Kw/m. This is made possible with the application of specialised element wire in combination with improved element design. They are suitable for applications directly in the atmosphere so that the high potential is fully utilised through a combination of radiation and convection.

 

IRON CHROMIUM (FECRAL)
This alloy can be formed into spiral or strip elements to suit the specific application where wire temperatures up to 1 400° C is required.

FEATURES

  • Manufactured in lengths up to 2 000 mm long
  • Manufactured in 0.53 mm or 0.62 mm

CAPABILITIES

  • Depending on wire choice, suitable for applications up to 1 200° C
  • High power output

 

SILICON CARBIDE ELEMENTS

Manufactured from high quality pure alpha silicon carbide grit and sintered at temperatures over 2 200° C. These elements form recrystallized rods with string uniform bonds known as silicon carbide elements. They can then be applied to various temperature applications ranging from 600 - 1 600° C.

FEATURES AND CAPABILITIES

  • Manufactured in various standard lengths and diameters
  • Manufactured as single or multi-leg units
  • Withstands rapid heating, cooling cycles and high electrical loading
  • High power output
  • Metal melting and holding furnaces

 

ELEMENT POCKETS

Element pockets are manufactured from various diameters stainless steel tubing with a wall thickness of 1,2 mm for maximum heat dissipation into the product to be heated. The pockets can be manufactured to any length in increments of 25 mm with hot and cold zones to suit your specific application. Withdrawable elements can then be removed or replaced without having to decommission the tank/vessel that is being heated.

 

CERAMIC WITHDRAWABLE ELEMENTS

Manufactured specifically for liquid heating, and houses in steel element sleeves the elements can be applied in the sides of tanks or as elements bundles on flanged assemblies. This design of element facilitates the replacement of elements without the draining of the tank or vessel in which it is applied resulting in reduced maintenance time and increased productivity.

FEATURES

  • Sizes are available from Ø16 mm - Ø54 mm
  • Custom manufactured wattages, voltages and lengths
  • Excellent dielectric strength
  • High mass construction retains heat longer
