LuniWash Barrier Washers LW 60 DS - LW 200 DS Series
Positioning of the drum
Automatic outer door locking system and positioning of the drum.
The drum, with the external door closed, requires the pressing of a special button to automatically position it to load and unload the laundry.
Single Motor, 29 KW power, driven by an inverter.
Maximum Extraction Speed 620 rpm (G-Factor 327).
Capability of choosing the speed of the drum both during washing and during the extraction cycle.
Transmission with elastic, high efficiency V-belts.
Pneumatic regulated mechanic brake for emergency stop, with safety lock, in case of power or compressed air failure.
Barrier Washer Extractors
Convenient detergent container with two trays for powder detergents, completely in INOX AISI 316 stainless steel, and three trays in PVC for liquid additives.
The first stainless steel basin is equipped with a button that allows its manual operation at any time.
Scheduled entry of additives, hydraulic and electric pre-setting, with eight interface relays, for connection to a Detergents Dosing Distribution Box.
Up to eight products can be connected as standard.
Stainless steel float equipment for adjusting three different water levels, with visual control through a rectangular porthole on the two fronts of the machine.
Each level is independent and can be raised or lowered at the customer’s discretion.
With pneumatic valve ∅ 140 mm
(it is possible to provide an additional drain for water recovery, on request).
A special tube provides external air directly to the machine. There is, therefore. no air flow between the two rooms.
Schneider Electric Microprocessor (TeleMecanique)
Schneider Electric Color Tactile Display (Touch Screen) 5,7″
Memory capacity: 35 programs.
Possibility to read and, if necessary, correct already introduced programs.
Display of the performance of the washing cycle with indication of the phase in progress (soaking, pre-wash, washing or rinsing) and the operation in progress (water inlet, product entry, operating time, etc.)
Continuous display of the temperature in the tank and the time elapsed since the start of the cycle.
Display of date and time.
Possibility of interrupting a washing cycle (with possible opening of the external door) to restart from the same point, or by pressing two special keys, to advance or return to an operation already performed (the program progress and return keys can be blocked by entering a code).
Possibility of manually intervening on the automatic cycle.
Possibility to insert a Bell (ringtone) in the program or at the end of it.
Mixing hot and cold water at the desired temperature (without the aid of Steam or Diathermic Oil).
Independent temperature at each phase of the cycle.
Cool down (gradual cooling of the washing bath temperature) essential for washing synthetic fibers that would be ruined by a sudden temperature change.
The cooling of the washing bath temperature must, usually, take place at a rate of 3-4°C/minute.
Gradual raising of the washing bath temperature (used for special products, generally in dyeing cycles).
Automatism Check Control
The functions and performance of the Washer Extractor is controlled by Check Control, that in the event of an anomaly or simply an oversight (for example the failure to open the water inlet valve to provide water to the system) signals to the operator with an intermittent sound and a message that appears on the keyboard, displaying the relative cause stopping the cycle.
This is a considerable help to the maintenance service, as in addition to quickly addressing the problem, it also indicates the proper way to intervene.
Here is a short list of alarms displayed by the Check Control. More detailed information can be found on the operator’s manual.
Tilt – Unbalance
Motor Magnet Thermal Probe
Contaminated Side Door Open
Sterile Side Door Open
Heating Water Absence
Water Presence in Distribution
Water Presence in Drainage
The Washer Extractors are built according to the safety regulations in force and to the European Machine Directive (CE MARK).
Particular attention has been given to the safety of the operators during the loading and unloading phases. It is, in fact, impossible to open the two outer doors at the same time or to control the rotation of the drum while any of the outer doors are open.
On the sterile side of the machine, an orange flashing light signals to the operator that the automatic cycle is complete and the laundry can be unloaded.
When the operator opens the door on the sterile side, a red light flashes constantly on the contaminated side, indicating that an operation is in progress.
At the end of the unloading operation, the operator closes the outer door, presses a button and signals that it is possible to restart a new cycle in the contaminated side.
Due to the balance suspension system, there are minimum vibrations to the floor, so there is no need for special mounting.
The machines do not need particular or expensive concrete foundations.
They are simply set on a prepared base. See the relative drawing for more information.

Exact consumption levels can only be calculated by knowing the exact washing cycle.
To allow the calculation of the necessary liters of water (Hot, Softened Cold or Hard water) see the chart above, which indicates the amount of water necessary, depending on the state of the laundry (Dry, Soaked or Wrung), to reach the chosen level (the calculations refer to the three levels set before delivery of the Washer Extractor).
Please note: if the Washer Extractor is equipped with an optional drain (available on request), it is possible to recover the rinsing water (usually the water is recovered after two rinses), which is stored in a tank (prepared by the customer) equipped with a suitable filter and be reused in the next washing cycle.
Direct Steam Consumption
The Direct Steam Consumption is about 120 kg for a standard cycle.
This consumption is, however, directly dependent on the temperatures of the washing cycle and the incoming hot water.
Electric Power Consumption
The Electric Power Consumption is about 9 KW/h for a standard washing cycle.
