Installing Gas Drying Tumblers in
the European Union (EU)
General Information
This information is to be used when installing gas
tumblers in countries and/or on gases different than the
machine’s factory configuration. Tumblers are
supplied from the factory for operaton on Natural Gas
or L.P. Gas in the countries of GB/IE/PT/ES/IT. To
install machines in any other country or on any other
gas requires some level of modification.
Models are built in three different configurations:
● Regulated Natural Gas
– Injector is sized for
Natural Gas, second family, group H (E) at
20 mbar inlet pressure. Regulator/governor is
operational. Gas valve CAN be field-converted
to a non-regulating type.
● Unregulated Natural Gas
– Injector is sized for
Natural Gas, second family, group E+ at
20.25 mbar inlet pressure. Regulator/governor is
blocked open. Gas valve CAN be field-converted
to a regulating type.
● Unregulated L.P. (Liquified Petroleum) Gas –
Injector is sized for L.P. Gas, third family, group
3+ at 28.37 mbar inlet pressure. Regulator/
governor is blocked open. Gas valve CAN be
field-converted to a regulating type.
Serial plates supplied from the factory are configured
for one of the three gases for the countries of GB/IE/
PT/ES/IT. This information pertains to situations when
the country of use or gas supply is different than that
on the serial plate.
Table 3 , Table 4 and Table 5 describe the different
gases that are available in different EU countries, and
how the machines need to be configured to operate
with those gases. In the EU, there are Natural Gases
that do not allow for machine regulation, and L.P.
Gases that must be regulated. For L.P. Gas, third
family B/P at 50 mbar, order Regulated Natural Gas
machines and convert according to tables.
WARNING
To reduce the risk of electric shock, fire,
explosion, serious injury or death:
• Disconnect electric power to the
tumbler before servicing.
• Close gas shut-off valve to gas tumbler
before servicing.
• Close steam valve to steam tumbler
before servicing.
• Never start the tumbler with any guards/
panels removed.
• Whenever ground wires are removed
during servicing, these ground wires
must be reconnected to ensure that the
tumbler is properly grounded.
