Open Winding Bobbin Heater
Open Winding Bobbin Heaters are specialized heating elements designed primarily for use in air or liquid heating applications where direct contact is possible. These heaters consist of a resistance wire (usually nickel-chrome) wound on a high-temperature ceramic bobbin. The open coil design allows for rapid heat transfer and high efficiency, making them ideal for immersion in oil tanks, chemical baths, and air ducts when inserted into a metallic protection tube.
Key Features
- High surface temperature with fast heat-up time
- Excellent thermal efficiency due to open coil design
- Suitable for immersion in oil and other non-corrosive fluids (with protection tube)
- Compact and lightweight with easy maintenance
- Operates at high temperatures (up to 800°C)
- Can be custom designed to fit different lengths and wattage requirements
- Available with or without metallic protection sheath
Applications
- Oil heating in storage or circulation tanks
- Chemical and acid bath heating (with suitable protection tube)
- Air heating in ducts or furnaces
- Industrial washing and degreasing tanks
- Water heating systems (non-corrosive environments)
- Textile, food, and pharmaceutical industries
