Tube Furnace

Some of laboratory processes where atmosphere control is vital, require a tube furnace to be used. Alser AS manufactures tube furnaces of various tube diameters and heated lengths. Through application of Kanthal wire and silicon carbide heating elements the temperature range extends to 1600°C as operation temperature.

The work tube is always price inclusive and is either Mullite or Recrystallized Alumina. Outer case has an attactive epoxy powder paint and the outer mesh cover maintains a cooler skin for maximum operator safety. Available in the horizontal or vertical models or in Universal mode where the furnace can be arranged to operate at vertical or horizontal or at a degree.

Optional consumables include gas tight end fittings of NiCr Steel for controlled atmospheres and vacum applications. Heat shields are provided to minimise heat loss at high temperatures. We also optionally offer a secondary (indicating)thermocouple for better recording of inside of tube during heat up.

• We can provide furnaces with a most any of work tube size but those mentioned in the list are usually kept in stock.
• Optional Consumables are End Fittings for the special atmosphere applications. Over temperature alarm relay as standart with all furnaces that employ SiC heating elements.
• We provide a limited Warranty for all of Protherm furnaces against faulty workmanship. But heating elements and ceramic work tubes are for consumption and is not covered by our warranty clause. We keep all spares at our stocks for quick delivery whenever a change is required.
• We can supply gas tight end fittings of stainless steel for controlled atmospheres as an option. We now have 2 models for this purpose ,namely Vacuum which is water cooled and Inert Gas types. Pls specify depending on your gas applications. Heat shields and insulating end plugs for tube furnaces will be supplied free of charge.
• Standart mode for Tube furnaces are horizontal, when required vertical models are also possible for a minimal extra charge, please ask for quotations.
• Universal models where both vertical and horizontal operation Pls note that there is an extra charge for this 
  modification , are available for almost every model.
