CAUTION
Proper selection of thermal fl uid is
critical to system performance.
the system. This is especially important during commissioning, when any
air trapped in the system is vented at high points, and when water, which
will fl ash into steam, is either expelled from the deaerator vent or drained
off at low points.
Selecting a Thermal Fluid
The selection of the thermal fl uid most suited to your application is very
important. Factors to be considered include effi
ciency, thermal stability,
adaptability to various systems, and physical properties, including vapor
pressure, freezing point, and fl ash and fi re points.
Heat transfer fl uids of both mineral and synthetic origin have been specially
developed to give thermal stability over a very wide range of temperature. A
wide variety of thermal fl uids have been used successfully in Fulton Thermal
Fluid Heater systems, however, your fi nal selection should be made in
conjunction with recommendations from Fulton Thermal Corporation or the fl uid
manufacturer.
Consider the following for selection:
1. The Fulton vertical tubeless thermal fl uid heater is a fi red heat exchanger
and the safe control and monitoring of the thermal fl uid temperature is of
paramount importance.
2. The safe maximum bulk temperature of the fl uid must be strictly adhered
to. The safe maximum temperature of the fl uid varies.
3. Special care must be taken when consulting fl uid manufacturers’ literature,
as maximum fl uid temperatures quoted are the actual limit to which any
of the fl uids may be subjected. It is important to remember that in any
fi red heater there exists a “fi lm temperature” which is higher than the
temperature of the “bulk” of the fl uid. It is the BULK fl uid temperature and
NOT the FILM temperature that is indicated by the instruments.
4. As a general guide, the following list of fl uids that have given satisfactory
service over many years is provided. This is by no means a complete list.
Any fl uid specifi cally designed for heat transfer use may be considered;
multipurpose oils are not acceptable.
