Product Description

Industrial Electric Coil Heating Element

 

Product Description

 

1. Coil Heater Working Principle

Flat coil heater are designed to the standard with respect to precise fit and profiling to optimize the performance of nozzles and other mating components.

They accommodate type "J" or "K" type thermocouple that could be placed internally at the tip or the middle of a heater.

They can be made as well to have profiled or distributed wattage configuration.


2 . Advantages

1. Flexible cold section
2. Higher watt density than a cable heater
3. Sealed transition head for moisture resistant applications available
4. Resistance wire centered for more repeatable heat profile
5. Outside sheath to improve heating efficiency
6. Temperatures up to 1800°F (982°C)
7. Precise temperature control
8. Built-in type J or K Thermocouple
9. Rugged, durable construction
10. Unheated straight section
11. Choice of lead protection
12. Made to customer specifications
