Spring Nozzle Heater Coil Heater
Introduction
Heater Coil is an advance concept of thermal engineering which has a construction similar to high watt density cartridge heaters. The basic concept of these heaters consists of compacted MgO, high temperature Nickel-chrome resistance wire and chrome nickel steel tube. These heaters also known as high performance tubular heaters or cable heaters. These heaters can be constructed with or without built in thermocouple.
HONGTAI produces Coil Heaters that guarantee the best as for multiple applications and executions. The essential development of these heaters comprises of compacted MgO, High Temperature Nickel-Chrome Resistance Wire and Nickel-Chrome Tube. These heaters can be built with or without inherent thermocouples. They are generally utilized on hot runner spouts and manifolds.
