MI coil heater, also known as mineral insulated coil heater, is specialized electric heater designed for a wide range of industrial applications where high-temperature and precise heating are required. These heaters are highly durable and can operate in demanding environments.

Construction: MI coil heaters are constructed using a mineral-insulated (MI) cable, which consists of a metallic sheath, typically made of stainless steel, surrounding a mineral insulation material.

High-Temperature Capability: MI coil heaters are designed to withstand extremely high temperatures, making them suitable for applications that require elevated heat levels, such as moulding and plastic processing
