Coil Heaters
Coil heaters have a construction which is similar to high watt density cartridge heaters. These heaters are also known as high performance tubular heaters or cable heaters. They are used when you require highly focused heat with a low profile. They are usually installed where space available for heating is limited and are widely used on hot runner nozzles, and manifolds, die cast nozzles, packaging machines etc.
Applications :
- Hot Runner Nozzzles
- Cutting And Sealing Bars
- Medical Equipment
- Rod, Pipe And Tube Heating
- Heat Tracing
- Semiconductor Manufacturing
