High Tech Features AWD 655-15 DIN (Where available) :

The 2 USB ports are located on the front:

  • USB 2 type A for PC USB: allows to connect the machine to a PC for programming;
  • USB 2 type B for flash drive: allows to download the history of programs executed and alarms, or for update the firmware and dataset.

The RS232 port allows to connect the machine to a printer or to a centralized traceability system.

The machine is equipped with a sensor placed in the suction probe of chemical products, which warn the user if the liquid is running out through a warning that appears on the LCD display.

The dosing system for chemical products is controlled by a flowmeter. If the flowmeter doesn’t perceive the passage of the liquid, after a few seconds the display will show an alarm that warns the operator of the non-dispensing of the liquid in the wash chamber, causing a cycle stop.

The machine is equipped with an effective steam condenser system that acts to reduce the steam during the disinfection and drying phases.

A dedicated vacuum switch monitors the filter clogging. An alarm message on the display will indicate that the filter is clogged, causing a cycle stop.

On request, the machine is equipped with a printer that prints the receipt log of the running program.

It is a system that makes it possible to soften the cold and hot water entering the wash chamber, so as to reduce the formation of limestone in the hydraulic circuit of the machine. The machine automatically regenerates the resins based on the water hardness set at the time of installation.

On request, the machine is equipped with a conductivity probe that checks the water purity level at the end of rinsing, before disinfection. The machine repeats the rinse cycle again to remove any residue if the conductivity probe detects a water purity level, expressed in μS/cm, higher than the preset one.

On request, the machine is equipped with the spray arm monitor system. If the spray arm monitor is enabled, it checks the correct rotation of the spray arm. An alarm message on the display will indicate a problem during the cycle.

The machine is equipped with a microcontroller that constantly monitors its operation. It’s provided with an internal flash memory that allows the machine to store all the information regarding: cycle params, allarms and log history. An internal watchdog monitor the microcontroller and block the device in case of a malfunction.

Thanks to a dedicated pressure switch that monitors in real time the water pressure of the washing circuit, all the washing parameters will be always perfect. An alarm message on the display will indicate if there’s a pressure lost during the cycle, causing a cycle stop.

The machine is supplied with a set of standard programs, variable according to the model. It is possible to add some customizable programs, up to a maximum of 40 total programs.

The door is made of two layers of tempered glass, resistant to chemicals, even the most aggressive ones. It allows to see inside the wash chamber during operation.

The wash chamber is made of stainless steel AISI 316L (EN 1.4404) while the chassis and external panels are made of stainless steel AISI 304 (EN 1.4301). They are shockproof and long-lasting. Scotch Brite surface finish makes cleaning easier.

The machine is equipped with an automatic door locking system which ensure a safety door block. For the safety of the operators, the machine does not allow the door to be unlocked during the wash cycle or in the presence of high temperatures. An extra sensor guarantee that, even if in presence of a malfunction of the machine, the water pump will be switched off with the unlock of the door.

The touch control panel consists of a 7” LCD display. The flat display with colour graphics shows all cycle parameters, alarm messages, measured temperatures of the
two temperature probes positioned in the wash chamber, drying temperatures and A0 value. The model with double door is equipped with screen monitor on both sides.

This system helps the operator to understand why an alarm has occurred before consulting the user manual. A text appears on the display with
the number, the image of the alarm and the text explaining the possible causes of it.

The machine can be customized with two interlocked doors: one for loading baskets and the other positioned at the rear for unloading them. The machines does not allow the unlocking of the two doors at the same time. The door in the unloading area is unlocked only if a cycle is successfully completed.

On request, the machine can be equipped with a LED light positioned inside the wash chamber, with low energy consumption, for a better visibility during the wash cycle and during loading and unloading of the basket or trolley.

The tanks are located in a compartment at the bottom of the machine, with locked door to prevent the access to unauthorized persons.

On request, the machine can be equipped with a humidity sensor that monitors the humidity value in the washing chamber at the end of the drying phase. Using a humidity probe, the device automatically regulates the duration of the drying phase in order to obtain a predefined drying result.

Speeds up the water heating times with additional hot and deionized water preheating boilers to speed up the washing and disinfection phases. Total cycle time is reduced by up to 50%!
The boiler is filled with deionized water maintained at a preset temperature thanks to its internal heating element. The boiler is filled during the disinfection phase using the heat of the condenser, reducing the electricity consumption and increasing system efficiency. For the disinfection phase, the chamber is filled with the preheated water from the boiler.

The E.T.S. (Empty Total System) system at the end of each cycle, automatically discharges the residual water from the pump, water storage tank and pipes, to ensure complete cleaning inside the machine.

During the drying phase the forced air, pushed by a blower, is introduced into the washing chamber, passing through an electric heater. The air then
comes out of the jets of the impellers to ensure a warm uniform air distribution. The HEPA H14 filter allows to block the fine dust present in the air with an efficiency of 99.995%. Furthermore, in order not to damage the filter, a pre-filter is placed in front of it to block the larger particles.

The water is heated both by the heating elements inside the tank and by the network steam. In this way it is possible to reduce program times and electricity consumption

On request, the machine can be enabled to understand when a trolley is inserted: it is not possible to start a program if there is no trolley inside the wash chamber. The application recognizes which type of trolley is inserted and suggests to the user which program to start. However, it remains possible to enable or disable programs that are not recommended for this type of trolley.

The user can open and close the door without remove his gloves by activating the optical sensor on the touch panel. This feature supports the cross infection prevention.

The user can start the machine without removing his gloves by pushing the buttons with the elbow. This feature also supports the cross infection prevention.
