Triogen CH2-50-1, Installation & Operating Instructions Manual

Page: 6 / 24

DESCRIPTION OF EQUIPMENT
Triogen compact air dryers are fully automatic desiccant dryers which are
electronically controlled for reliability and ease of use.
The dryer contains two desiccant columns with integral heater elements, two
three-port solenoid valves, an air pump for purging moisture from the
columns, all of which are controlled by a programmable relay.
When one column is drying the air, the other column automatically heats up
and the small purge pump passes air in reverse flow through the column to
drive out the moisture retained within the desiccant material. After a pre-set
period of time, the heater and pump are switched off to allow time for the
column to cool down prior to it going on stream to allow regeneration of the
other column.
This process is continuous unless the unit is switched off. Automatic cycling
of the air dryer columns is controlled by a no-maintenance programmable
relay ensuring no loss of cycling sequence when the unit is switched off.

Triogen compact ozone generators comprise three main components – a
high voltage, high frequency power board driving a ceramic corona discharge
module which is air cooled by an integral cooling fan.
Normal atmospheric air can be used as the feed gas, or pre-dried air supplied
by a Triogen compact air dryer, either of which is drawn through the ozone
generator under vacuum which is created by a water driven venturi injector.
When the unit is switched on, an electrical corona discharge is formed within
the module by the power being supplied from the board. This reforms the
oxygen molecules (O
2
) present in the feed gas into ozone (O
3
) as the air
passes through the module.
As heat is produced by the generation of the corona discharge, it is
necessary to cool the module during operation. This is achieved by the use of
an integral cooling fan fitted within the ozone generator.
The high voltage, high frequency power board incorporates full overload and
short circuit protection. In addition a thermostat is fitted to the module which
will isolate the power in the event of a cooling fan failure causing the module
to overheat.
The ozone generator is fitted with an output control knob, located on the
underside of the unit adjacent to the pipe connectors, which electrically varies
the ozone output between 50% and 100% of the rated output of the unit.
