Bobbin Heater
Bobbin Heaters
Heatandcool provides For any voltage or wattage within manufacturing constraints, ceramic bobbin heaters are made from high-temperature factory insulators in a range of diameters and lengths. Both sheathed and non-sheathed materials are used to make bobbin warmers.
Stainless steel, Inconel alloys, and nickel-plated mild steel are among the materials used for the sheath. Resistance wires are attached to a terminal block at one end and supported on refractory insulators. For precise temperature sensing, a thermowell or additional controls may be included. Although they can be expressly designed and built for vertical installation, they are typically created for horizontal mounting.
Advantages
- Suitable for low temperature up to 600°C furnace heating
- A wide range of lengths, voltages, and power is available to meet customers' specific requirement
- Simple and low-cost installation
- Ease of maintenance and repair
- Versatile and non-polluting
- Energy-efficient as 100% of the heat generated is within the solution
Application Areas
- Water, chemicals, etc
- Offer for semi-solid materials like wax, fats, oil, and bitumen
- Suitable for indirect heating of gases and liquids, where it is inserted into a pocket or protection tube in the process tank, wherein, it can be repaired or replaced without draining the process tank.
