W-type Molybdenum Disilicide MoSi2 Industrial Heating Elements

Horizontally mounted MoSi2 Heating elements can be used for applications where the roof of the furnace is particularly low. Four-shank elements could be used where the surface temperature of the element does not exceed 1800℃ (3272℉) in such cases. And these types of elements are available in 3/6, 4/9, 6/12, 9/18 and 12/24 sizes.

Advantages of multi-shank elements over two-shank ones:

• having longer hot zones;
• using fewer elements;
• reducing the cold end losses.

Following should be provided when ordering W Type MoSi2 Heating Elements:

• Grade: 1700, 1800 or 1900
• Diameter: D1/D2, in/in or mm/mm
• Heated Length: Le*, in. or mm
• Terminal length: Lu*, in. or mm
• Shank Spacing: A*, in. or mm
• Specify Le, Lu and A with the same units (e.g. all as in. or mm).

Examples:
Grade 1800, D1=3mm, D2=6mm, Le=5.5in., Lu=5in., A=.98in.
Specify as: MS18W, 3/6-5.5-5-0.98in.
Grade 1700, D1=6mm, D2=12mm, Le=300mm, Lu=250mm, A=50m
Specify as: MS17W, 6/12-300-250-50mm

USEFUL ELEMENT TEMPERATURES IN VARIOUS ATMOSPHERES, ºC (ºF)

Note: For inquiry, it is better to provide a drawing of the element and specify the element diameters in millimeters. For example, an element with a (D₁) diameter of 9 mm and a (D₂) diameter of 18 mm is often referred to as a 9/18 element. Other dimensions may be specified in millimeters or inches.
