The machines referred to in this book have drum volumes of 120 and

220 litres and are high speed spin washing machines with flexible

programmes. They are intended for installation in hotels, laundries,

industry, hospitals, small institutions etc.

The machines differ in size and capacity.

The machines are free-swinging, ie, the drum is moveable and spring

suspended in relation to the frame. This minimises vibrations

transferred to the frame thus simplifying installation, as no concrete

base is required.

The drum rotates at distribution speed thus distributing the washing

before the spin. This also reduces vibration caused by imbalande.

The distribution speed and the drain provide effective water removal.

The high speed spin gives a G factor of approximately 300, providing

very efficient water removal during the spin.

The washing programs are programmed by means of programmable

cards.

The machines are supplied in accordance with the customer's

specifications, i.e. for heating by electricity, steam, gas or without

heating. Standard conversion kits are available to convert electrical

heating to steam heating.

The machines are also available in different water connection options

with cold, hot and cold hard water.

The machine is a free-swinging model i.e. the outer drum and motor

bridge and suspended in the machine chassis via a spring

suspension with a strong spring in each corner of the machine. Each

spring has a shock absorber which dampens the movement of the

machine.

The wash drum or inner drum is driven by two motors via a V-belt:

one motor for washing and distribution speed and one for spin speed.

The inner drum is mounted in the outer drum with two heavy duty

bearings at the back plate and is sealed with two V-rings.

The motors are suspended underneath on a motor support with a belt

tensioning device. The motors are mechanically coupled to each

other with V-belts. During wash and distribution speed the spin motor

transmits power to the drum.

The water inlet and drain are both situated under the outer drum. This

improves the flow during filling and prevents water vapour from

entering the detergent compartment.

The robust square door is locked with a handle which is interlocked

by a safety locking device when the machine is running.

The operating panel contains several buttons for manual control of

certain functions: restart button; indication light; thermostat and a flat-

card unit through which programmed cards can control the washing

programmes.

Reverses, level switches, relays etc are placed in the automatic unit,

which is easily accessible from above and can be replaced via a

plug-in system.

The machine housing consists of hot-dip galvanised, painted steel

plates and stainless steel sheets, painted on the front and sides. It

has a stainless door (and front, on request).
