Print unit / intermediate dryers

Print unit / intermediate dryers

Menschick print unit dryers are perfectly suited for intermediate dryer installations on in-line flexo as well as rotogravure printing machines. Frequently, they are operated as vertical dryers. However, print unit dryers are usually a part of the print unit. Thus, integration as well as customization should always be realized in cooperation with the print unit manufacturer. Both, single dryer (mostly just upward) and twin dryer configurations (up- and downward) are common.

In most cases, nozzle dryers without built-in air supply are used for print unit dryer solutions, because they allow an easy and flexible adaption to the existing installation and size conditions.

They have also proved successfully without integration into a print unit, such as a stand-alone application or horizontal dryer. For external air supply and heating of such dryers we recommend the use of our Menschick hot air boxes that perfectly complement our drying solutions.

Menschick intermediate dryers are also available with a built-in air fan and heater. They are particularly suited for print units, to which an addition of such dryers is technically feasible.
