Notes on Safety
In this manual, you will find various notes categorized under the following levels with the signal
words “DANGER” and “CAUTION”.
DANGER Indica es a hazardous si ua ion which, if ma erialized, could resul in a
serious injury and even in dea h.
CAUTION Indica es a hazardous si ua ion which, if ma erialized, could resul in
ma erial damage or a modera e injury.
DANGER
Never use the in ut and out ut signals of the unit for o erations that may
threaten human life, cause damage to the system.
Turn off the ower su ly when you set u the unit, connect new cables, or
erform maintenance or ins ections. Failure to do so could cause electric shock
or damage to the unit.
Never touch any terminals while the ower is on. Otherwise, electric shock may
occur.
CAUTION
Periodically check that the terminal screws on the ower su ly terminal block
and mounting nuts are firmly tightened. Using the unit with loose screws may
result in fire or malfunction.
Connect the cables correctly to the
ower su ly
terminals of the unit in
accordance with the s ecified voltage and wattage. Failure to su ly the
correct voltage or wattage, or im ro er cable connection may cause fire,
malfunction, or damage to the unit

1APPLICATIONS
MANVIA DG-50 System offers a new design for conductivity measurement for water-steam cycle
chemistry monitoring. This system ensures an effective CO₂ removal from sam le and an
a ro riate tem erature conditioning for an accurate degassed conductivity measurement.
Therefore, maximizing ower roduction and minimizing corrosion of equi ment. Furthermore,
o tional sam le self-cooling is available.

3GENERAL DESCRIPTION
The objective of the degassing system is to raise the tem erature of the sam le to its boiling oint,
in order to remove the greatest amount of CO₂ from it. To maximize the extraction efficiency of
CO₂ and minimize the roduction of water va or, recise tem erature control has been designed
by means of a control loo formed by a tem erature controller, an RTD and a heating cartridge
that rovides the necessary heat, to raise and maintain the tem erature at the required set oint.
The CO₂ extracted from the sam le leaves the atmos here through a tube, which travels through
the interior of a cooler, which guarantees that, in case of va or occur at any time, it will condense
and will be removed by means of the general drainage of the system.
Drainage funnel
After the elimination of CO₂, the sam le requires cooling to erform a measurement of degassed
conductivity under o timal conditions. That is why the sam le is directed to a cooler, for the
o eration of which, there are two o tions: Sam le is cooled with cooling water from an external
source or it exchanges heat with itself, by assing the sam le through the cooler rior to assing
through the heater.

The o tion of self-cooling, guarantees great stability to the system in the event of disturbances in
the flow or tem erature of the sam le, as well as, not requiring a consum tion of cooling water
and the installation required for cooling water su ly.

4INSTALLATION
CAUTION: THE NECESSARY PROTECTIVE EQUIPMENT MUST BE USED IN ORDER TO AVOID
KNOCKS, CUTS AND ENTRAPMENTS DURING INSTALLATION. FOLLOW THIS PROCEDURE FOR
CORRECT INSTALLATION.
4.1 Mechanical
This device must be located avoiding vibrations and direct ex osition to sunlight. The system incor orates
four holes in the four corners of degassing system anel, in order to fix it to a vertical wall. The degassing
system must be mounted in vertical osition, using four M-10 bolts in order to fix it to a smooth and bare
wall. It is im ortant that in normal o eration, the rear art of the mounting late doesn’t be accessible in
order to avoid burns to o erators.

Cooling water connections
Cooling water connections are not required when self-cooling o tion is installed. In case of external cooling
water o tion, follow next ste s:
•Kee the length of all tubing to a minimum. Only 80 mm of straight tube, must be res ected
from connection fitting (¼” NPTF) to the revious curve u stream.
•Connect the cooling water IN. Should be i ed to the left lower side of the mounting late, in
¼” nominal bore tube and connected by means of ¼” NPTM fitting to ¼ NPTF connector.
Connection is labelled with the indication “COOLING W. IN”.
•Pi e the cooling water OUT. Should be i ed to the left lower side of the mounting late, in ¼”
nominal bore tube and connected by means of ¼” NPTM fitting to ¼ NPTF connector.
Connection is labelled with the indication “COOLING W. OUT”.
