Customizable

We design our machines to be as much customizable as possible.

You can choose the power, which needs to be installed and we do the rest. DOE Swan is designed to be as compact as possible. Vertical heater placement decreases maintenance space and is very easy to use.

Stainless steel bended frame makes the unit light and robust at the same time.
