The various components of the newly developed microwave unit type MICROKUR are of modular design. Special emphasis was placed in development on easy access to the unit as well as ease of operation and maintenance. The microwave channel is used to heat polar, compact and microporous rubber compounds. The rubber compounds must be suited to absorption of microwave energy. With a compound that is suitable for microwave curing an energy absorption efficiency of 60 - 80 % can be achieved.

The housing consists of a sturdy frame with insulated sheet metal covering. The channel and housing covers are operated pneumatically. During normal operation, the covers are locked in position and electronically interlocked for safety. The large angle of opening allows easy access to the internal channel areas. The smooth inner channel walls are of anodized aluminum, are good heat conductors and reduce microwave leakage. The expansion of the channel partitions are compensated for by floating bearing assemblies.

The intake- and exit-side channel openings reduce microwave leakage to acceptable levels through highly absorbent special materials. Easily adjustable templates on the channel openings allow easy adaptation for various profile cross sections.
