'As little as possible but as much as necessary'. This principle is an expression of Miele's understanding of sustainability as applied to developments in the field of medical technology. All machines use only the amount of water, energy and process chemicals needed to achieve excellent cleaning performance and disinfection results. For many applications, there are special programmes, e.g. 'OxiVario', for heavily soiled and challenging instruments or 'Ophthalmology' for the delicate instruments used in eye surgery, which ensure excellent reprocessing standards with a minimum of resources. This protects not only the environment but also reduces the need to repurchase extremely expensive instruments too frequently.
As water consumption in the various programmes is kept as low as possible, only a commensurate amount of energy is required for heating. Alongside electrical heating, Miele decontamination units are able to connect to an existing steam supply as an environmentally friendly and economical source of energy.
Other aspects to sustainability as demonstrated by Miele washer-disinfectors are durability and longevity. Miele's proverbial and legendary quality lies behind the promise of more than 20 years of reliable service. A whole battery of excrutiating endurance tests ensures superb quality even before series production starts. High-quality materials, for example the polymers used in valves and gaskets or the filters in drying units, ensure high resistance to temperature and process chemicals. Filter replacement intervals of up to 1000 hours both protect nature and go easy on financial budgets.
Forward-thinking and sustainable product planning also takes into account that customers are likely to want to use existing accessories such as baskets and transportation and dispensing systems on newly purchased washer-disinfectors from the most recent series, proving that sustainability creates long-term benefits.
