We are pleased to inform you that we currently do not expect any effects from the corona virus on the delivery of our units.

The reason is the high proportion of in-house production of the systems produced by Gustav Klein in Germany and Austria and the care measures initiated by us at an early stage.

We are in constant contact with our most important suppliers and are informed about all relevant changes in the situation.

Concerning our service at site we restrict it to the absolute necessary operations.
