Contact SupplierWalta Heater Private Limited manufactures high-performance Open Coil Heaters, designed for rapid and uniform heat transfer in demanding industrial environments. Known for their exceptional thermal efficiency and extended service life, these heaters feature a distinctive open design where resistance wire is securely crimped onto terminals and suspended between high-grade ceramic insulators.
The exposed resistance coil design allows for direct contact with air flow, maximizing heat transfer efficiency and ensuring quick response times. These heaters are highly customizable and can be engineered with various wire gauges, coil diameters, and termination styles to fit specific furnaces, HVAC systems, and processing equipment.
Whether for semiconductor manufacturing or general air heating, our open coil heaters provide reliable stability and safety during operation.
Key Features:
Rapid Heat Transfer: Exposed coil design ensures direct and immediate air heating.
High Temperature Capable: Operates efficiently up to 1100°C.
Premium Materials: Made using Nichrome (80/20, 70/30) or Kanthal (A1, APM) wire.
Customizable Design: Voltage, power, diameter, and length tailored to application needs.
Versatile Application: Suitable for vacuum environments, cast-in heaters, and air ducts.
