LAIYUAN Heater manufactures a wide range of cartridge heaters also known as immersion heaters for a variety of applications. The size, sheath, leads, terminals, wattage and voltage can be adapted to meet your heating requirement needs.

 

 

Cartridge Heaters are our most popular product. We make low to medium cartridge and high watt density cartridge heaters. Cartridge heaters provide localized heat to restricted work areas requiring close thermal control. Dies, platens and a variety of other types of processing equipment are efficiently heated. Closely controlled work temperatures up to 1400° F (760 C) are obtained by a combination of heater location and proper wattage output.

 

 

LAIYUAN heater is a leading electric heating manufacture and can provide heating solutions to your specifications to accommodate your application and heating needs. Backer Hotwatt stocks all material for the different diameter units listed in the catalog. Your order, specifying the wattage, voltage, diameter, length and lead type is readily and quickly fabricated from our inventory. In addition, many standard sizes are available from our In Stock Cartridge Heaters for immediate delivery.

 

Cartridge Heater Applications

 

Compressor Crankcase Heating, Copiers, Dies, Food Processing, Glue Pots, Heat Sealing, Hot Melt Adhesive, Labeling, Medical Equipment, Packaging, Photographic Processing, Plastic Molding, Platens, Wax Pots and Shoe Machinery.

 

CARTRIDGE TYPES

 

Original old standby made with ceramic supported wire insertion into a metal tube filled with loose fill inorganic ceramic powder (usually magnesium oxide). Cross sections can be round from 1/8 inch diameter to 2 inches diameter; square, hexagon, triangular, etc. Cross sections are also available; length can be from < 1 inch to > 4 feet.This is usually the first choice consideration for OEMs and accounts for an estimated 20% of total electric heaters made. Power density is < 100 watts per square inch and temperature up to 1200 degrees F are possible.

 

Standard Cartridges Usually made inside a metal tube that looks like a bullet Cartridge; a possible source of its name. Various types listed below.

 

Compacted Cartridges Developed about 60 years ago, possible influenced by the good power density capacity of roll compacted tubular, said units by nature of compacting the inorganic power tightly to the resistance wire makes an excellent unit. Compacted cartridges power density increased compared to un-compacted cartridges in units less than 500 watts per square inch. Compacted heating units also can approach 1800 degrees F. The requirement for higher quality tubing (to withstand rolling/swaging compaction), precision fired crushable ceramic internal parts plus the added compaction operation make this unit 1 ½ – 3 times standard cartridge cost. They are available from most vendors in diameters from 1/8 inch to 1 inch and length from 1 inch to > 3 feet. A first choice for OEMs that need high power density/temp. inside a small envelope.
