Miele thermal disinfectors: Powerful, safe, convenient

No. 078/2016

Revolutionary cleaning technology for dental practices

The washer-disinfectors from Miele Professional are more powerful and safer than ever before. The undercounter models offer maximum reprocessing capacity, innovative drying and top-class user convenience.

At the heart of this series of 60 cm and 90 cm wide units is an innovative water circulation system which combines higher capacity with the reduced use of resources. A patented, variable-speed circulation pump regulates water pressure in line with the needs of individual programme phases. This saves both water and energy. All the heating elements are integrated into the circulation pump and are hence no longer visible inside the chamber and can therefore no longer cause soil to accumulate. In combination with the smooth, laser-welded chamber seams, this sets high standards in terms of hygiene. Furthermore, the pump heats up the water in circulation fast, thereby contributing towards shorter cycles.

The introduction of both water and drying air into load carriers has also undergone improvements. Both now enter the cabinet via the rear panel and not, as previously the case, via the chamber ceiling. The water is then channelled through a horizontal spray guide to the spray arm in a loss-free way, resulting in the more efficient use of resources. A special feature: Any valves not used by docked baskets are sealed automatically in order to avoid any unnecessary drop in pressure in the remaining system and in order to reduce water consumption. Spray arm and spray pressure monitoring guarantees proper reprocessing.

When it comes to drying instruments, this generation of machines combines efficiency with user convenience. After the last rinse cycle, steam is drawn into the steam condenser at the rear of the unit where it condenses back to water. On models with the EcoDry feature, the machine door automatically opens at the end of a programme once the temperature in the cabinet has dropped below 70°C. This allows remaining the moisture-laden air to escape within a short space of time, leaving the load reliably dry and allowing items to cool down fast.

On models with active DryPlus drying, moisture remaining in the cabinet is absorbed by the heated drying air and expelled to atmosphere via the steam condenser. A highly efficient HEPA Class H13 particulate filter prevents air-borne particles from the ambient room air from entering the drying system and contaminating the instruments.

On all models, the door is automatically drawn closed by the AutoClose function: All that is required on the part of the user is to simply lean the door to. Additional convenience and excellent ergonomics is offered by the  patented salt container which has now been relocated from inside the chamber to the door. Replenishing salt is extremely simple and easy on the back and can even be performed with the machine loaded, without having to remove the lower basket for access.

The high-end control panel also doubles up as a door handle, for a perfect fusion of design and function. Touch-on-steel technology makes for exceedingly simple operation and ease of cleaning. A quick tap on the screen is sufficient to select and launch programmes. The display in the centre of the control panel provides information on programme selection – in the user's own language. Optionally, various parameters such as actual temperature or the cycle number can be displayed. The three most frequently used programmes can be saved as favourites and launched at the tap of a fingertip using the quick selection button.

Everyday work in practices is simplified by a upper basket with its 22 injector nozzles. This basket can be fitted with the appropriate accessories for the reprocessing of all types of lumened dental instruments – from saliva extractors to turbines, hand-pieces and contra-angles. An adapter is available to facilitate the connection of transmission instruments of different sizes. It is simple to use and automatically provides a secure hold for each instrument. Stainless-steel retainers also ensure that instruments are held securely during reprocessing and minimise contact points on the outside of instruments.

The internal cleaning of transmission instruments is reliant on the good filtration of the wash liquor in circulation. For this purpose, a central tubular filter has been created which considerably cuts costs to users. They are inserted into injector rails and can be simply removed for cleaning. Compared with the approach adopted on the previous series, the filter increases the  surface by almost 300%, reliably protecting expensive instruments against damage caused by foreign matter.

In order to facilitate the complete documentation of process data from reprocessing equipment, disinfectors can be hooked up to a dental practice's network to allow a software programme to collate and archive data. Alternatively, machines can naturally also be connected to a printer for the documentation of data.
