Air-cooled systems have evolved to become more thermally efficient that normal heater designs as a result of geometric changes and implementation of sophisticated shrouding and airflow techniques. Air-cooled heaters require little maintenance and therefore, when properly installed and applied, have the capability to outlast and outperform liquid-cooled models. However, it is crucial to follow recommended installation techniques.

These include:

• Allow sufficient space for thermal expansion. The amount of space required depends upon the heater size and.operating temperatures.
• Keep the surface to be heated free of any foreign material. Likewise, to effectively employ an air-cooled shroud, the surface to be heated should have a smooth finish.
• After the initial heatup, retighten the clamping devices to ensure good surface contact.
• Use thermal insulation to reduce heat losses, but be sure that the insulation does not come in contact with heaters.
• Avoid mounting the heaters in an atmosphere containing combustible gases and vapours.

On In conclusion, while this primer about the variety of heater types can help with the initial step of heater selection, a manufacturer of heaters will be able to help with more detailed information regarding your specific application. With the range of designs and options, however, for certain, there is a air cooled heater suited to your needs.
