Demineralized water for instrument decontamination:

A water treatment unit is connected to the water supply in the decontamination room. Tap water is subject to a reverse osmosis or ion exchange procedure to produce demineralized water.

Demineralized water, also called feed water or aqua dem, is required for the operation of a steam sterilizer. A washer disinfector can also be operated via a water treatment unit. Given strongly mineralized tap water, the final rinse with demineralized water prevents stain development or surface alteration of the instruments in practice and clinic.

The requirements placed on demineralized water are stipulated in the European Standard DIN EN 13060 Appendix C.

The water treatment system supplies the autoclave with demineralised water and provides the basis for maintaining the value of the autoclave, thermal disinfector and instruments.
In our video tutorial you will learn how to exchange the e.g. MELAdem 40 cartridges of your autoclave quickly and easily in your practice:

Water Treatment Unit MELAdem 53

The optimal accessories for MELAG water treatment units

MELAjet, MELAtest 60, bacteria filter and water stop

MELAG water treatment units save a lot of time and money in a medical and dental context. The versatile accessories of the MELAdem series provide even more advantages:

Use the MELAjet spray pistol to draw demineralized water directly from the water treatment unit MELAdem 40, MELAdem 53 or MELAdem 53 C and to fill the stand-alone steam sterilizers or for other purposes. This obviates the time-consuming need to procure and dispose of aqua dem containers.

After manual instrument decontamination, the MELAjet can also be used to rinse the instruments thoroughly using a point jet or a cone spray. This is reliable in removing cleaning fluids and disinfectants from the instruments. The use of further Luer-Lock adapters mean that even hollow body instruments can be connected and checked for passage.

Accessories for the water treatment units

The integrated conductivity measurement with which MELAG autoclaves and washer disinfectors are fitted performs an automatic check of the water quality before every program start. Given direct removal of the demineralized water, this check can be performed using the MELAtest 60 conductivity meter. MELAtest 60 determines the precise water quality within a measuring range of 0.1 to 99.0 Microsiemens (µS/cm).

The Bacteria filter for MELAdem 47 water treatment unit ensures microbiologically-faultless water. The micro-fine filter effects a further significant reduction in the bacteria content of the water. Increased demands placed on the microbiological quality of the demineralized water by medical clinics practising minimally-invasive surgery will be served by using the bacteria filter.

Those using a water treatment unit or steam sterilizer with a fixed water connection benefit from the extra security provided by the MELAG water stop. Water egress from the device causes the interruption of the water inflow. Installation of the MELAG water stop helps to locate leaks, thereby avoiding water damage.
