By spirals material:

• Metal.
• Ceramic.

By form:

• Open. Mounted at a certain distance from the sprayer. Because of the special conditions they have a short lifespan.
• Closed. placed in a high-temperature-resistant housing. They have a long service life.

By location:

• In systems with separate combustion chamber - in the vortex or the settling chamber.
• In the inseparable chambers – in the chamber itself.

By the number of spirals:

• With one coil. Differ by accurate setting the required temperature, stability and performance.
• With the double helix. This kit allows you to more accurately adjust the temperature balance.

According to the degree of heating:

• Cold.
• Average.
• Hot.
• Very hot.
