microwave conveyor furnace MWD 28x1 kW
Mikrowellendurchlaufanlage MWD 28x1kW

The continous microwave conveyor furnaceMWD 28x1kW has a usable opening area of W 800 x H 300 mm. The furnace is subdivided into 6 single modules. Depending on the used magnetron type each module has a microwave power of 28 or 56 kW. The whole length including the absorbing zones at the in- and outlet is approx. 10 m. The microwave generators are located above and below the conveyor belt. The special design of the microwave antennas guarantees a very homogeneous field distribution in the tunnel. Doors on the sidewalls of the furnace give full access to the conveyor belt. Microwave power and belt velocity are continiously controlable.

microwave flow heater MDE 6x1 kW
Mikrowellen-Durchlauferhitzer MDE 6x1kW

The microwave flow heater MDE 6x1 kW is designed for heating chemical and pharmaceutical liquids. The flow through plastic tube withstands aggressive media and makes possible fast and precise temperature control. E.g. this is important during galvanic processes. Tube diameters up to 40 mm can be realized. The flow heater has a total power of 6 or 12 kW. If more power is needed, the flow heaters can be cascaded.

microwave flow heater MDE 1,2 kW
Mikrowellen-Durchlauferhitzer MDE 1,2kW

The microwave flow heater MDE 1,2 kW is used for the preheating of glass fibres in pultrusion. With different applicators profile diameters up to 50 mm can be treated. A three stub tuner guarantees good matching to different loads. The microwave power can be adjusted without any inertia, so temperature control even at high speeds is no problem.

applicator PUL 3xCF
dreisträngige Applikator PUL 3xCF

The applicator PUL 3xCF is used for the preheating of three carbon fibre bundles at the same time. Carbon fibre pultrusion was very difficult until yet, because the conductive fibres cause a large leakage radiation. With a special design of the in- and outlets of the applicator it was possible to decrease the radiation to a legal limit.
