Hot air boxes for nozzle dryers

External air supply for convective dryers

Menschick hot air boxes have been specially designed for external air supply and heating of nozzle dryers without built-in supply units. As a result, our hot air boxes are well suited for print unit / intermediate dryers that do not have an integrated air fan and heating. However, their use is not limited to such applications. Menschick hot air boxes are perfectly suited for hot air supply of various systems, not least dryers, ovens and chambers based on convection, but without internal air supply..

Hot air boxes are particularly advantageous because of their compact and space-saving design. Each technical component or function that is necessary for air supply, air heating and optimal recirculation of equipment such as nozzle dryers is clearly arranged within one device. This avoids confusing and space consuming installations of fans, heating chambers, pipes and ventilation dampers quite often found within printing machines.
