Mini Coil Heaters Electric Heaters
Product Description
1. Coil Heater Working Principle
Mini coil heater, is a small size coil heater with smaller diameter nozzle or nozzle tip that can also be formed in grooves.
Because of its small size, mini coil heater are widely designed with a pressed on sheath, pressed into brass, or serve as the heat source for Hotlock, and Axial Clamp heaters.
The Hotlock design protects the mini coil heater with an inside, outside stainless sheath and enclosed end rings for superior durability.
2. Advantage
Replace the external thermocouple
Proven durable heater for tight space constraints
Staggered or single transition head configurations
Profiled for more heat at the Tip

4. Coil Heater Imported Raw Materials
a. The coil heater resistance is used
German Nickel Chrome wire, can be coiled and straight.
b. The insulation material magnesium oxide powder is imported from
USA; which ensures the high performance, fast response time and good unformity.
5. Surface Treatment
Blasting and blackening surface treatment, also can provide bright surface.
