| |
Full Vestibule
|
|
Full vestibule heaters have a vestibule at both ends of the cylinder. A vestibule is a section at the end of the cylinder with a reduced inner diameter, but the same outer diameter as the rest of the cylinder.
|
| |
Left Vestibule
|
|
Left vestibule heaters have a vestibule at the left end of the cylinder. The right end of the cylinder remains open, with the same inner and outer diameter as the rest of the cylinder.
|
| |
Right Vestibule
|
|
Right vestibule heaters have a vestibule at the right end of the cylinder. The left end of the cylinder remains open, with the same inner and outer diameter as the rest of the cylinder.
|
| |
No Vestibule
|
|
No-vestibule heaters have constant inner and outer diameters throughout the length of the cylinder.

|
| |
Custom Design
|
|
The heater can be custom-designed and configured. Custom designs are configured in coordination with the manufacturer.
|
| |
Dynamic Power Regulation
|
|
Dynamic power regulation regulates the power output from the heater so that parts are heated at the proper rate.
|
| |
Explosion-Proof
|
|
The heater's housing is designed to withstand explosions and protect the materials within. Some suppliers include heaters with housings that can withstand sparking and flames.
|
| |
Encased Coil
|
|
The coil is encased in a casting for protection and to maximize heat transfer.
|
| |
Finned
|
|
The heater has fins for better heat dissipation.
