Our selection of quality cartridge heaters (also known as rod heaters or insertion heaters offer exceptional durability and performance through advanced designs, superior materials and rigorous manufacturing standards. They provide corrosion resistance and efficient heat transfers. As dependable cartridge heaters suppliers our reliable brands are built for long life and more uniform temperatures.
Cartridge/insertion heater construction consists of an electric heating coil surrounded by a tube-shaped metal case. These industrial heaters come in a wide variety of diameters and lengths. They provide excellent vibration resistance.
Standard Insertion Heater
- High Temperature Lead Wires for Temperatures up to 550° C.
- Stainless Steel Sheath can support up to 1000 F and Incolloy Sheath can support up to 1400° F.
- High Impact Ceramic Cap retards contamination and is suitable for high vibration applications. Deep holes in cap prevent fraying of leads when bent.
- Nickel-Chromium Resistance Wire for maximum heater life, evenly wound for even heat distribution.
- High Purity Magnesium Oxide fill selected for maximum dielectric strength and thermal conductivity, highly compacted for maximum heat transfer.
- 304 Stainless Steel Sheath for oxidation resistance in a wide variety of environments. 316 Stainless Steel.
- TIG Welded End Disc to prevent contamination and moisture absorption
Split Sheath Cartridge Heater
Use a unique, patented split-sheath design that expands when energized to maximize heat transfer through greater contact with the wall of the bore. Better heat transfer means less power is consumed to maintain the set point temperature, reducing operating costs.
Custom Cartridge Heaters
Used for process heating, a rod heater is sometimes referred to as an insertion heater. This is because the unit is inserted into a specially drilled hole to heat metal parts or small areas. Each industrial rod heater will come in a specific watt density. Leads and voltages also vary between models.
We have high-watt or medium-watt density rod heaters available. First-class materials and manufacturing are featured in our durable rod heaters for commercial applications. Our knowledgeable Hi-Watt team will help you locate the best industrial electric heaters for your needs, so call today.
