ATTENTION!
• It is prohibited to install machines with gas heating
in rooms where appliances are installed that use
perchloroethylene or similar products (dry cleaning).
This is valid for any type of gas.
5.3 STEAM SUPPLY CONNECTION (ONLY FOR MACHINES
WITH THIS TYPE OF HEATING)
The appliance is prepared for the inlet of saturated and
(without the presence of air) dry (without the presence
of condensate) air and a condensate drain with diameter
described in the technical data. The pressure of the inlet
steam pressure must be between 1 and 6 bar (0.1 MPa and
0.6 MPa).
In all cases consult the appliance plate data.
Dryers with steam heating must be installed in compliance
with the local and national laws in force. The steam supply
piping and gate valves and condensate return must be
appropriately dimensioned depending on the steam
pressure, temperature and requirements of the machine
(steam consumption); however, the diameter must not
be smaller than the inlet and outlet attachments onto the
dryer.
The appliance has a steam inlet, into which the supplied
steam electrovalve is connected (normally inserted in the
drum).
The appliance has a condensate output which is connected
to a trap, dimensioned on the basis of the distance between
the outlet and the trap itself and the features of the plant.
ATTENTION!
• A fine mesh filter must be installed upstream from
the electrovalve to prevent impurities present in the
line damage the electrovalve membrane. A shut-off
gate valve must also be installed that is indispensable
for performing repairs, maintenance or emergencies.
• It is always advisable to mount a non-return valve
downstream from the trap in a way to prevent
condensate returning into the same. A shut-off gate
valve is indispensable to perform maintenance,
repairs or emergencies and is a passage indicator that
confirms the correct functioning of the steam plant.
Other elements such as pipe bleeding devices, heat
exchangers, pumps for condensate rising, superheaters and
support lungs must be used depending on the type of plant
and dryer performance.
Below is a list of some condensate discharge features mainly
used.
5.3.1.1 THERMOSTATIC TRAP WITH LIQUID DILATION
Does not withhold condensate and is therefore not subject
to freezing. High discharge capacity also when cold. The
minimum distance between the dryer output and the trap is
2 metres. It does not accept large steam pressure changes.
The flexible element does not accept the presence of
corrosive condensate.
5.3.1.2 BIMETAL THERMOSTATIC TRAP
As well as the qualities of the previous type, it has a greater
resistance to blows and corrosive condensate. However it is
not recommended where a temperature control is present.
5.3.1.3 TRAP WITH FLOAT
Accepts sudden variations in load and pressure. Easily
discharges the air present in the pipes. In the case of
maintenance or faults it has simple construction and is
easy to repair. Immediate condensate discharge. The float
does not support corrosive condensate, blow or overheated
steam. The choice must be made depending on the working
pressure.
5.3.1.4 INVERTED BUCKET STEAM TRAP
Accepts blows and overheated steam. On request it can
be envisioned to support corrosive condensate. Simple
construction. Its correct functioning implies perfect
dimensioning. It is slower to respond to pressure and load
variations. If the pressure should drop continuous steam
passages can be created.
5.3.1.5 THERMODYNAMIC TRAP
Smaller dimensions than previous models. Large condensate
discharge capacity. They have a wide temperature and
pressure working range. They also work with overheated
steam, also in the presence of corrosive condensate. Accepts
blows well. There are no risks of freezing if the drain faces
downwards. It does not work with pressures below 0.3 bar
and with counter-pressures at the drain greater than 80% of
the inlet pressure.
ATTENTION!
• It is recommended to use components that are
suitable for the pressure and temperature of the
steam and condensate.
