The new PG 8527 (single-door) and PG 8528 (barrier) decontamination units have aleady proved their worth out in the field. Several units have been put through their paces at the Rhön Klinikum in Germany's Bad Neustadt and in laboratories affiliated to the Centre for Molecular Biology at the University of Heidelberg. The CSSD at the University Clinic in Cologne has also placed an order for a multiple-unit installation.
Both models feature Miele's new, simple-to-use PerfectTouch display. This display and the controls are set in a perfectly flush glass screen, allowing simple and effective surface disinfection. All sensor-touch controls are behind glass, with only slight pressure on the surface needed to select the required functions. Programmes can be launched at the touch of a single control. Display contents and layout and an optional printout of the process protocol can be reconfigured to suit individual requirements.
'PerfectSpeed': Monitoring of spray arm speeds
The machine's display indicates whether rotational speeds are within the specified range or whether intervention is needed, for example on account of rotation of the lower spray arm being slowed down by an excessive build-up of foam. Both disinfectors feature Miele's unique 'PerfectSpeed' spray arm control unit as standard. 'PerfectSpeed' allows the precise rotational speed of each spray arm in the cabinet to be monitored and documented.
A new dispensing volume control system under the name of 'PerfectFlow' offers a much higher degree of safety than previous systems. This system is able to ensure precise volumetric control, irrespective of the viscosity of the product and the nature of on-site conditions (uninterrupted continuous operation and installation sites with fluctuating climatic conditions). Such a precise and sophisticated approach makes this system far superior to the more usual flowmeter type systems.
'PerfectPure': conductivity monitoring detects residues in wash liquor
Even the slightest traces of residue in wash liquor can seriously impair reprocessing results. Residual alkalinity in the wash liquor can, for example, cause severe side-effects and injuries in eye operations. Another optional extra from Miele is a new and totally maintenance-free conductivity measuring system which deduces the presence of residuals in the wash liquor from conductivity levels. The meter is located in the water circuit between the circulation pump and the upper and lower spray arms and does not come into any physical contact with the wash liquor.
Hygiene and convenience benefits
Further innovations ensure enhanced hygiene and improved user convenience. These include the new cove-cornered cabinet made from high-grade stainless steel with sloping horizontal surfaces designed to induce self-drainage and improve hygiene. An optional all-glass 'PerfectVision' door in combination with special in-cabinet lighting ensures an excellent view into the cabinet. This allows the positioning of the load to be checked at all times during reprocessing. During the drying phase, a high-temperatue HEPA filter directly upstream from the cabinet prevents the entrance of undesirable particulate material and thereby ensures optimum hygiene.
With the new features, Miele decontamination units set new standards in the reprocessing of instruments and laboratory glassware.
Compact system based on 60 cm wide slot-in units
Where space is at a premium, the new 60 cm washer-disinfector with integrated 'Drying Plus' fan-assisted drying represents the ideal solution. This model ensures particularly effective drying despite the constraints of space. Consequently the G 7892 fits the bill perfectly in surgeries and ward-end applications in hospitals.
Hot-air drying ensures the rapid and reliable drying of all interior and exterior load surfaces. An integrated HEPA filter ensures the purity of the air used for drying. Users can enjoy the same load capacity on a smaller footprint with the new models, which take up considerably less space than other machines as they dispense with the side drying unit.
This washer-disinfector can be combined with Miele's new reverse osmosis unit, available for installation in a neighbouring cabinet or in a plinth, providing the fully demineralised water recommended for the final rinse.
