Information  WDS Specifications

The WDS has been designed to provide combined capabilities of a bedpan ⁄ urine bottle washer disinfector, and a utensil ⁄ bowl washer disinfector, without the additional cost and space necessitated by having separate machines. This allows more space and budget to be allocated to more income producing activities, such as additional beds, operating theatres etc.

ARTG Certificate


The WDS has gone through a thorough and exhaustive R & D program, including site trials at a number of facilities. Malmet has listened to the needs of both clinical and engineering staff and has designed the WDS to meet the requirements of all our clients, whether it be a large metropolitan hospital, a smaller regional hospital, or an aged care facility.
