Marathon makes coil heaters which are an advance concept of thermal engineering & are also known as high performance tubular or cable heaters. Coil heaters offers high heating profile within the coil section. They are available with variety of wattages, surface loads, high performance in compact spaces up to temperature as high as 750°C. They can be constructed with or without built-in thermocouples for temperature control. Coil heaters are available in many different size options from straight & coil form. Coil heaters are used in variety of industries & are economically feasible one. Coil heaters can be closely wound to provide concentrated heat or can be stretched to fulfil distribution wattage needs. Coil heaters are also available with various exit styles & configurations to suit the requirement of the application.
