24V 150W Industrial Cartridge Heater Element

Swaged vs. Standard Cartridge Heater Design and Heater Life span

For confined work spaces needing precise temperature control, 24V 150W industrial cartridge heater element deliver focused heat. The equipment used for processing is effectively heated, including dies, platens, and several other pieces. By carefully balancing heater placement and wattage output, it is possible to achieve tightly regulated work temperatures up to 1400° F (760° C).

How effectively heat is transferred from the resistance wire and into the component being heated affects how long a cartridge heater lasts. Three elements in general govern how efficiently heat is transferred:

1. Watt density of resistance wire

2. The amount of insulation surrounding the wire.

3. Fit of the heater into the heated part

24V 150W industrial cartridge heater element come in two different basic types: swaged and standard. Although the interior structure of the two types of heaters appears to be the same, it is extremely different.

Standard Cartridge Heater Design:Ceramic tubes have holes drilled into them for the insertion of nichrome wire heating coils. To maximize the amount of heat transmission to the stainless steel sheath, pure magnesium oxide filler is vibrated into the holes housing the heating coils. The heater is then mounted with insulated leads and a Heliarc welded end cap on the bottom. Heat transmission from the uncompressed MGO powder to the heater sheath and finally into the heated area depends on the grain-to-grain thermal conductivity. The heater wire's watt density must be kept in the low to medium range as a result.

24V 150W industrial cartridge heater element Swaged Cartridge Heater Design:Swaged cartridge heaters carefully place the resistance wire and ceramic core within the heater sheath while winding Nichrome wire around the core. After that, the heater is swaged to a certain diameter and pure magnesium oxide (MgO) powder is vibrated in. In order to lower the heater's diameter and compact the powdered MgO to a rock-like consistency for improved thermal conductivity, the heater is physically forced through a restricting die. The heat from the resistance wire is transferred from much more effectively by this compressed MGO. Swaged cartridge heaters may run at greater temperatures thanks to the enhanced heat transmission, which enables larger wire watt densities.
