System supplier for WC cubicles in rail vehicles

The special thing about vacuum toilets from Dowaldwerke GmbH is the pneumatically driven squeeze valves. In contrast to frequently used sliding valves, our valves guarantee permanent functioning to dramatically drive down failure rates and servicing expenditures. The valve sleeves are so robust that even sharp or pointed objects do not damage them. We know because we have put it to the test with glass fragments, knife blades and even thumb tacks. 

We have added failure rectification and frost emptying routines to its normal flushing and servicing function such as normal, service and back flushing. The frost emptying routine can be adapted to your special cubicle design.

We develop the hardware and software for our products ourselves within our corporate group.
