Description of operation (Fig. 1.4)
When the ironer control requests heating, the microprocessor opens the solenoid valve (B), allowing the steam
to enter the roll (F) through a two-way rotary seal (E).
The contact of the fabric with the ironing surface cools the steam inside the container. As the steam changes to
liquid (G), the condensate (under pressure) is drawn by a siphon tube (H) through the same rotary seal and
expelled to the outside via a steam trap (K) that prevents the exit of steam and releases any air that may be
found inside.
The input filter (A) protects the valve from any impurities that may be present in the steam supply circuit.
The output filter (J) protects the steam trap from any impurities.
The safety valve (C) prevents the container from being subjected to a pressure higher than the maximum
allowed.
The pressure gauge (L) indicates the pressure inside the roll.

1.4. Machines with electric heating. Description

Set of electrical elements mounted on a support that keeps them positioned close to the inner surface of the roll.
Depending on the model and voltage of each machine, they are controlled by one or two contactors.
See the wiring diagram in the documentation supplied with the machine.
