High density pencil heaters are a type of electric heating element that are designed to provide high watt densities in a compact and durable package. These heaters are often used in applications where space is limited, such as in the heating of small pipes, tanks, and containers.Pencil Heaters are also called Cartridge heaters, Insertion heaters, rod heater or single head heaters.

Pencil Heaters are also called Cartridge heaters, Insertion heaters, rod heater or single head heaters. Because there is only one wire end, and the shape looks like a pencil, So we call the cartridge heaters also Pencil heaters. Jaye makes the Pencil heaters with high density and highly compacted in order to get the best heating transfer efficiency. Our pencil cartridge heaters all are custom made, the size are not limited, such as 6.5mm, 8mm, 9.5mm, 10mm, 12mm, 12.5mm, 16mm, 18mm, 19mm, 20mm and 25mm. are very normal size, we can make more than you can imagine.
The heating element in a high density pencil heater is typically made from a high-resistance wire, such as nichrome or kanthal, that is coiled tightly around a ceramic or metallic core. The core provides mechanical support for the wire and helps to distribute the heat evenly along the length of the heating element.
| Heating element wire | Nickel-chromium resistance wire precisely wound on magnesium oxide core.to get the best heating transfer and keep long life time service. |
| Pipe Material | Stainless Steel is used as the standard sheath material on our Pencil cartridge heaters. And the material of the stainless steel pipes are also available to be selected, such as the SUS304, SUS316, SUS321, Incoloy840 or Incoloy800, etc. |
| Built-in thermocouple | An optional feature on the cartridge is a built-in thermocouple. They can be "J" or "K" type, grounded or ungrounded, and connected to the end or the middle of the disc of the pencil heaters. |
| Moisture-proof and pollution-proof: | In order to prevent the cartridge heater from being damp and polluted, PTFE wire is used, and the lead end is sealed with epoxy resin, RTV silicone resin or PTFE. |

• High density cartridge heaters are available with various termination styles and mounting attachments
High Watt Density: High density pencil heaters are designed to provide a high watt density, typically between 60 and 80 watts per square inch. This means that they can provide a high level of heat output in a compact package.
Compact Size: High density pencil heaters are very compact and can be easily installed in tight spaces. This makes them ideal for applications where space is limited.
Rapid Heating: Due to their high watt density, high density pencil heaters can heat up quickly, allowing for fast warm-up times.
Uniform Heat Distribution: The coiled wire element inside the heater helps to distribute heat evenly along the length of the heating element, ensuring uniform heating of the material being heated.
High Temperature Resistance: High density pencil heaters are typically able to withstand high temperatures up to 1200°C, making them suitable for high-temperature applications.
Durable Construction: High density pencil heaters are typically made from high-quality materials, such as stainless steel, which are resistant to corrosion and wear. This makes them suitable for use in harsh operating conditions.
Precise Temperature Control: High density pencil heaters can be used with temperature controllers to provide precise temperature control, ensuring that the material being heated is not overheated or underheated.
Store the heater in a dry place, especially during periods of high humidity.
Protect the wires from abuse and wear.
All Pencil cartridge heaters are hygroscopic and will accumulate moisture during transportation and storage. Low heater insulation (less than 1 megohm) can be baked in the oven for several hours or activated at low pressure to eliminate moisture.
The compact size and high watt density of high density pencil heaters make them well-suited for applications that require fast heating and precise temperature control. They can also be used in high-temperature environments, as they are typically able to withstand temperatures up to 1200°C.
When selecting a high density pencil heater, it is important to consider the voltage and wattage requirements of the application, as well as the size and shape of the heating element. It is also important to choose a heater with a high-quality insulation material and a durable metal sheath that can withstand the harsh operating conditions of the application.
Some common applications for high density pencil heaters include:
Plastic injection molding
Semiconductor processing
Food processing and packaging
Medical and laboratory equipment
Heating of small tanks and vessels
