Coil Heaters have very high heating power and are used in hot runner systems and various other thermal processes which require high electrical heating system in a small space. They have small diameter and can be bent and wounded in any pattern. This makes it suitable for large number of solid surface requiring heat. They are available in a wide range and can also be specially made according to the customers' requirement.
