Product Description

Coil Heater

Coil heater has a construction similar to high watt density cartridge heaters. These heaters are also known as high performance tubular heaters. The basic construction of these heaters consists of compacted MgO, high temperature resistance wire and Chrome Nickel Steel tube. These heaters can be constructed with or without built in thermocouples. The Coil Heaters are installed where space availability is limited for heating and are widely used on hot runner nozzles, and manifolds, die cast nozzles, packaging machines etc.
