Bundle Rod Heater
Bundle Rod Heater Solutions
Heater Dekho offers advanced Bundle Rod Heaters engineered for high-temperature radiant tube applications and heavy-duty industrial furnaces. Designed with premium grade heating alloys and robust ceramic support assemblies, these elements deliver maximum power output, rapid heat transfer, and extended service life across heat-treatment, annealing, and carburizing operations.
Max Temp: Up to 1250°C
Power: 3 kW to 100 kW
Radiant Tube Compatible
High Power Density
Bundle Rod Heater
Consists of circular ceramic beads that hold the heating elements. Designed for long life and maintenance-free operation in low voltages for faster heating. Can be mounted horizontally or vertically with ferritic alloys up to 1250°C and NiCr alloys up to 1100°C.
Key Benefits
- Reduced CO2 emissions avoiding corrosion from furnace gas.
- Convenient temperature control, easy assembly, and reliable sealing.
- Free from oxide debris with high watt density output.
- Cost-effective with higher resistivity and surface load.
