3.0 PRODUCT DESCRIPTION
3.1 Operation
The Peltier cell condensation group (Cooler) has the function of cooling the gas sample very quickly to a temper-
ature of 5 º C. The gas condenses the water vapor contained in it and can reach the sensors without significant
changes in its composition.
This system is particularly useful when water-soluble components are to be analyzed (e.g. SO2, NO2, NH3, H2S,
etc.).
Under extreme ambient temperature conditions (+45°C) it is possible that the cooler internal temperature is not
maintained at +5°C but it can tend to shift up to +10°C.
This internal temperature is however sufficient to obtain the drying of the gas; in these conditions it is possible to
lose 10% of the drying efficiency.
For automatic emptying of condensation water, a peristaltic pump is used which is controlled directly by the mi-
croprocessor at alternating on/off intervals to preserve the durability of the neoprene tube, an essential part of the
pump itself.
The duration of the switch on interval is 30 seconds, while the duration of the shutdown interval is 600 seconds
and cannot be changed by the operator.
The tube has an average duration of about 500 hours of continuous operation. To ensure the smooth operation of
the entire system, the rotor of the peristaltic pump (containing the neoprene tube) must be replaced at least every
two years.
3.2 Preliminary operations
Remove the product from the packaging used for shipment and proceed to a first inspection of the device.
Verify the correspondence of the content with what ordered. If you notice tampering or damaging signs, immedi-
ately report the fact to the SEITRON Service Center or its agent, keeping the original packaging.
On the product label there is the serial number of the external cooler.
It is recommended to provide this number for any request for technical assistance, spare parts or
technical information.
Seitron maintains updated at its headquarters an archive with the log of the data of each device.
