Mini MIcro Tubular 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.
Our Advantages

5. 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.
6. Surface Treatment
Blasting and blackening surface treatment, also can provide bright surface.

8. Coil Heater Cross Section
Based on specific requirements and applications, coil heaters are manufactured in different cross sections.
Each one is having its own advantages and disadvantages. Basically there are three types of coil heaters.
They are
| Coil Heater Cross Section |
| Round Coil Heater Diamater |
Φ3.0, Φ4.0,Φ5.0 |
| Square Coil Heater Diamater |
3.0×3.0, 3.3×3.3, 3.5×3.5, 4.0×4.0, 5.0×5.0 |
| Rectangular Coil Heater Diamater |
4.0×2.0, 4.2×2.2, 4.5×2.7 |
Cross section 4.2*2.2mm
