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).
