Standard-Square Swaged Cartridge Heaters

Our extended range of imperial square cartridge cross sectional dimensions was established to provide our customers with a full service source for virtually any square cartridge cross section required. A wide assortment of lead and seal options, construction variations and mounting options ensures compatibility with both new and existing heating applications.

 

Extended imperial cross sectional dimension range

All combinations of sizes and ratings available

Many popular lead and seal options

Standard integral sensor styles

Wide range of standard mounting options

Many standard construction options

 

Special Purpose-Square Swaged Cartridges

NPH manufactures a variety of special purpose square cartridge heaters for many common and specialized heating applications. These special purpose cartridges are designed to provide the optimum physical, thermal and electrical characteristics for the precise application for which they were designed.

 

Runnerless injection mold heaters

Thermoset mold and platen heaters

High performance heaters

High wattage immersion heaters

 

Custom-Square Swaged Cartridge Heaters

Custom square cartridge heaters can be manufactured to customer specifications or can be engineered to satisfy the specific requirements of special applications. Custom square cartridges often consist of standard units with relatively minor design modifications but may include a variety of the special features noted below.

 

Unique application oriented lead configurations

Special non-standard cross sectional dimensions

Extended temperature and wattage performance

Corrosion resistant and exotic sheath materials

Low voltage element designs

Special multiple sensor options

Unique custom engineered construction options

Special purpose mounting fittings

 

Square Cartridge Heaters Design and Construction Features:

 

Premium Quality Element Wire. Nickel-chromium resistance wire is precision wound on a high purity ceramic core to optimum computer generated gauge and pitch specifications. Element wires overlap the internal pins and are swaged into a metallurgical bond for optimum connection life.

 

Superior Element Positioning. Precise centering of the square element assembly

insures optimum heat uniformity around the cartridge periphery. The square element configuration positions the element wire in close proximity to the cartridge sheath providing rapid and efficient heat transfer to the application.

 

Densely Compacted Ceramic Insulation. The magnesium oxide ceramic insulation

is compressed to near theoretical density in order to provide the best combination of heat transfer and dielectric strength. This dense mass of compacted ceramic also provides maximum resistance to shock and vibration.

 

High Temperature Alloy Sheath. Available sheath materials include various

stainless steel and incoloy compositions. Additional metal sheath compositions

can also be supplied as applications dictate.

 

Welded End Seal. A square metal end disc of the same alloy as the sheath is

heli-arc welded into the end of the cartridge. This seal weld provides the positive

seal required for liquid heating applications as well as eliminating the possibility of contaminants entering the disc end of the cartridge.

 

Durable, Heat Resistant Lead Systems. The standard high temperature leads

exit from the cartridge through a protective ceramic end cap. The lead insulation

is recessed well into the cap to eliminate any possibility of exposing bare wire when bending the leads sharply at the lead end. Standard leads consist of ten inches of UL approved stranded wire. The lead wire insulation is UL rated for 842°F/450°C continuous operating temperature.

 

A wide variety of other standard and special purpose lead styles are also available.

 

Square Cartridge Heaters Selection Guide

The key questions which need to be answered before selecting a square cartridge heater for your application are:

 

How much wattage is required?

What voltage will be used?

What is the heated length? What is the overall length?

How long are the heater leads or what is the lead length required?

What are the the dimentions of the square cartridge heater?

What is the ambient temperature the square cartridge heater will see?

What is the maximum temperature required from the square cartridge heater?

How quickly do you want to reach your operating temperature or set point in hour/minutes?

What is the type and weight (in lbs.) of the material you want to heat?
