Cartridge Heaters
Cartridge Heaters Manufacturer and we provide tube-shaped, heavy-duty, industrial joule heating elements (electrical resistance) used in the process heating industry, usually custom manufactured to a specific watt density, based on its intended application. Cartridge Heaters provide superior heat transfer with uniform temperature and resistance from oxidation and corrosion at high temperatures. Our popular Cartridge heaters are the following design styles:
➤ Straight,
➤ Right Angle,
➤ Flange,
➤ 90 Degree,
➤ Posts out Both Ends,
➤ Post on Same End,
➤ Distributive Wattage.
Cartridge Heater Capabilities and Benefits:
- 304 Stainless Steel Sheath
- All heaters are swaged at 3/6 L for immersion applications
- Watt densities (guaranteed to 150) up to 200 W/in² (62 W/cm²)
- Part temperatures to 1000° F (540°C) for optional stainless steel sheath
- Part temperatures to 1400°F (760°C) on Incoloy ® sheath
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 Heater Advantages:
- A Cartridge Heater comes in handy wherever there is this need to apply a powerful source of heat to temper intricate metallic parts.
- In equipment and parts that are prone to condensation, like control panels and closed circuits, this sleek, simple-to-use heater is used to adjust air temperature.
- These heaters can be used to heat chemical solutions as well as water. Water naturally attracts energy, therefore it can effectively drain the power from the heating elements.
- The Cartridge Heater aids in maintaining the oil reservoir at ideal temperatures to enable smooth engine operation and is also utilised as an engine sump heater.
- To avoid overheating and carbon build-up, which can insulate the heater and cause a burn-out, choose a unit with the proper wattage once more.
History of Cartridge Heaters:
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 OEM’s 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 OEM’s that need high power density/temp. inside a small envelope.
