Considerable reduction in detergent consumption is 

achieved by diverting part of the fresh rinsed water 

(220litres/hour) to the pre-wash tank, with the remaining 

being used for the regeneration of the main wash tank. 

The water that is diverted to the pre-wash tank is then 

pumped to both the upper and the lower arms to pre-clean 

the soiled products, ensuring that larger food particles and 

liquid residues such as gravy and sauces are washed from 

the items, thereby reducing greatly the soil level on the 

items entering the machine’s main wash tank.  An optional 

Eco pre-scrap arm positioned just after the inlet in the 

pre-wash tank, will immediately start to “soften” and “wet” 

items as they enter the machine so it is especially useful 

to wash heavily soiled items or when the machine is used 

mainly on fast speed.

The water in the main wash tanks is pumped with detergent 

and is sprayed over the items from both the upper and 

the lower wash arms, guaranteeing a uniform distribution 

of the washing solution and allowing all the areas of the 

washing chambers to be covered. An option of variable 

pressure gives the possibility to increase up to 30% the 

pressure towards the lower wash arms and at the same 

time to slow down the belt speed in order to better wash 

boxes or heavily soiled items.

Rinse area equipped with the DUO-rinse system: the first 

rinse arm is filled with re-circulated rinse water to eliminate 

any trace of detergent, while the second ramp is filled with 

hot clean water to guarantee the sanitation of the items.

A drying section with inspection door (1100 mm wide) will 

be provided as an integral part of the machine. This allows 

the operator to remove practically dried items immediately, 

without them being too hot to handle.

Optional Energy Saving Device (ESD) utilizes heat and 

steam generated from the machine to pre-heat the 

incoming water. This reduces energy consumption by 

13 kWh by eliminating the need for an external boiler 

or water heater and allows the machine to be supplied 

with cold water up to 10° C. In addition, the double pipe 

in the optional Water Heat Exchanger will have a further 

energy saving of about 2 kWh as a result of the exchange 

in temperature between the used rinse water and the 

incoming fresh water. 

Thanks to the Energy Saving Device, the outgoing air from 

the machine will be cooler and less humid, eliminating the 

need for a ventilation hood, if the incoming water is about 

10 °C and the room has frequent air changes or is well 

ventilated.

Optional Heat pump operating in conjunction with the 

Energy Saving Device plus the Water Heat Exchanger, will 

heat up incoming cold final rinse water up to 65 °C before 

entering the boiler.

The conveyor belt is driven by means of a gear motor 

which will be protected against overcharge (as a result 

of blockage or for any other impediment), by a safety 

device mounted at the end of the unloading side.

Individual drain valves for each tank. Drain valves are 

automatically closed when the door is closed, so there is 

no risk of tank filling with open drain valves.

Counter balanced doors with safety switch and easy-to-

grip handle.

The machine incorporates a safety stop switch at the top 

of the discharge section which will automatically stop 

the conveyor in case that dishes, trays, containers, etc… 

have not been removed after cleaning.

Flat panel with electronic control that, thanks to the auto 

diagnostic control and the 32 digits window, is able to 

communicate in every moment, the working conditions 

of the appliance.

Electronic control panel incorporates the plug-in 

connection to link basic and integrated HACCP systems.

Pre-arrangements for external automatic detergent 

dispenser.

Two speeds, a fast speed for normal soiled items and 

a slow speed for heavily soiled items. As option the 

machine can be equipped with three variable speed 

selector: normal speed, slow speed for heavily soiled 

items and a third speed for 2 minute contact time 

according to DIN 10510. Each speed is individually 

adjustable.

The introduction of the Heat pump system allows 19 

kWh of energy savings; also the heating element in the 

boiler can also be reduced by 8kW. The exhaust air will 

be cooled down to about 15°C with very low humidity so 

that no ventilation hood is needed over the machine.
