The Smeg washer-disinfector WD7015 is based on a closed loop washing system with water intake completely renewed in each phase.
The hydraulic system loads 30 L of pre-filtered water, which is drained before the next phase by floor drain (or optional drain pump).
The particular shape of washing chamber minimizes the water consumption and ensures the constant pressure in washing circuit.
The mixing of additives with water occurs by means of peristaltic pumps inside the washing chamber and in a specific phase of the program. The additives concentration can be set for each program (mixing temperature and detergent dosing can be set for each program).
During the working phase, the washing pumps make the water and additives flow into the sprayer systems. The high rate flow/pressure, in conjunction with temperature and time, allow the removal and dilution of contaminants in the water. The electrical heating system or the optional steam heating system rapidly increases the temperature of water filled in the washing chamber without stopping the circulation and washing processes.
The smart management allows loading the water intake in relation to the rack to be used so that the water consumption and waste can be minimized.
The water flows into the sprayers placed on the ceiling and at the bottom of the washing chamber as well as into the manifold branches for rack injection or alternatively into the injection systems in relation to the glassware to be processed.
During the heating, the water keeps to flow into the sprayers and the washing process is not stopped.
In order to ensure a constant pressure on sprayers and consequently a good quality for cleansing, the machine steadily monitors if the washing pumps work in the best way.
The steam condenser, if present, works whenever the water heating generates vapour avoiding leak into the environment. All that means a better glassware drying. Furthermore, the steam condenser avoids the connection to an external air vent.
Specifically designed for high retention of particles and easy to access for maintenance.

Dosing System
The Smeg washer-disinfector WD7015(M) has n. 2 peristaltic pumps for default respectively for dosing the alkaline detergent during cleansing phase and for dosing acidic neutralizer
during neutralization phase. Each pump is equipped with its own level sensor placed inside the canister of the used product, with warning on display for empty canister. The dosing precision can be ensured by volumetric flowmeters (optional).
- n. 1 peristaltic pump for dosing liquid alkaline detergent
- n. 1 peristaltic pump for dosing liquid acidic neutralizer
- n. 2 peristaltic pump for dosing additive (optional)
Please refer to the programs table for further details on chemicals consumption.
The detergent compartment is an integral part of the machine on the unclean side; its design is suitable for storing up to 4 x 5 litres and 1 x 2 litres cans. It is equipped with a removable tray for easy cleaning in case of detergent leakages.
Steam Condenser
The steam condenser (optional) is a system for reducing the saturated vapour, normally produced because of the high temperatures involved for increasing the water temperature, especially in the thermal disinfection process.
This system avoids the formation of condensate in proximity of the machine and humidity emissions into the environment.
Limiting the heat dispersion emitted by the glassware in air-conditioned rooms the workload of conditioning system is slightly reduced as well as the electrical consumption and unwanted thermal shocks.
Drying System
The “INTELLIGENT DRY” drying system with forced hot air is very fast and highly efficient. This system consists of a couple of hot air generators and powerful fans to make the air flow. It is managed directly by the micro-controller which allow to set both the duration and the target temperature of the drying phase.
The most efficient drying temperature is automatically set by the control system for each of the program.
The hot airflow spreads evenly in the overall volume chamber and throughout the instrument hollows by virtue of the particular design made for sprayers and nozzles.
The drying target temperature can be set in the range [ 50 ÷ 110 ] °C.
The air extraction system is combined with a double stage HEPA filter designed to target most of the smallest pollutants and particles:
- Stage 1: pre-filter C class with 98% retention
- Stage 2: HEPA filter S class with 99.99% retention
Whenever the filter is no more efficient, the machine will show on display a warning for its substitution to ensure that the air purification is always kept at optimal level and no contamination occurs for instruments.
The drying system is equipped with fan speed control and hot airflow control at the entrance of the washing chamber.

Auxiliary Functions
- USB port fort downloading the performed cycles
- Ethernet port for LAN connection (optional)
The total verification of the thermal disinfection process is one of the most important aspects as explicitly required by the regulations. Therefore, it is essential that the washer-disinfectors are equipped with the necessary device for communicating data of the performed process. The Smeg washer-disinfector WD7015 has an USB serial port for default in order to download all the data related to washing and disinfection programs.
Traceability
- Tracing the washing and disinfection cycles is very important because it is a fundamental premise for the outcome verification of the overall process.
- The printer is an optional useful to report all the data related to the cycles performed by hard-copy.
- Alternatively, the machine can be connected to an archiving software by using the LAN port (optional). The Smeg models are compatible to the most common traceability software on the market.
EN15883 Compliance
The standard EN15883 specifies general performance requirements for washer-disinfectors related to quality assurance and process. The washer-disinfector WD7015 complies with the standard to ensure that washing cycles are controllable, verifiable and repeatable.
All the Smeg washer disinfectors are full in compliance with the standard and each technical solution implemented fulfil the requirements contained therein.
Among the various novelties introduced by EN15883 the most important is the A0-value concept. The EN15883 standard defines the A0-value, an important numerical value that puts in relation the two fundamental parameters of disinfection: temperature and time.
Basically the A0-value means how large is the lethality of the disinfection process for instrumentation. The washer-disinfector provides a wide range of programs with different A0-values for every need but it is also able to calculate and show the current value on the display and make a printout at the end of the cycle if the optional printer is installed.
LAN Connection
The new generation of Smeg glassware can be equipped with the WD-LAN60, an optional electronic board to connect the glassware to the available data LAN.
The LAN connection and the dedicated WD-CONNECT software make the new WD7015 series even more unique: it is possible to update the machine firmware with no hardware operations by a LAN connection or to download the cycles archive for traceability.
Available Options
- Booster pump for non-pressure demineralized water
- Additional peristaltic pumps (2)

- LED lighting for washing chamber
- Rack recognition system for automatic selecting the optimal washing program
- ECOSLIM Steam condenser

The use washer disinfector is fundamental also for processing hollow instruments, anaesthesia sets, containers, OR clogs, baby bottles and teats.
The Smeg washer-disinfector WD7015 is designed to work with the flexible racks, which are configurable to re-process different items, optimizing spaces and saving money.
Thanks to the high number of specifically designed accessories, Smeg offers a wide range of solutions to fulfil each single need.
It is also possible to work out on custom requirements for achieving tailored solutions.
Detergents and Additives
The thorough washing and effective instrumentation disinfection require the using of specific detergents. Smeg can provide you a wide range of alkaline detergents (for washing phase) and acidic neutralizers (for neutralization phase) which have been designed specifically to ensure an efficient cleansing so that the disinfection process can be optimal. Furthermore, Smeg offer various detergents for re-processing of thermo-sensitive instruments and anaesthesia sets as well as special lubricants and additives which are able to prolong the medical devices lifetime.
