Heating with hot air
Versatile and easy

Whatever kind of material you want to heat, Leister hot-air tools can help. Hot air provides a highly flexible way of controlling all kinds of heating processes. Hot air generated by air heaters or hot-air blowers is blown over the material that is to be heated. The energy in the air is transferred to the material, causing it to heat up. This convective heat transfer process takes place without any contact. Therefore, it really helps protect the material. What's more, the air does not leave any debris or residue behind on the surface of the material, which makes it very clean. It is not generally necessary to perform any subsequent cleaning processes. As a result, hot air is a very easy and flexible option for heating. The desired temperature can be set very precisely by selecting process parameters such as the heating power and air volume. Thanks to the wide array of Leister air heaters and hot-air blowers, the equipment can be efficiently tailored to the application concerned. The air heaters and hot-air blowers available range from 400 W to 40 kW. The potential heating applications are extremely diverse. However, preheating and defrosting are typical examples. For instance, semi-finished metal products are preheated prior to further processing in order to minimize delays. At very low temperatures, measuring instruments can sometimes fail if they are allowed to freeze. This problem can be reliably prevented by using Leister hot-air blowers or air heaters.

Leister has the solution
Leister air heaters and hot-air blowers can be used to heat up virtually anything. The wide power range means that you can select the optimum equipment for your process.
