CAUTION
Some soap used for leak testing is
corrosive to certain types of metals.
Clean all piping thoroughly after
completing the leak check.
Some plastics can be dissolved by
thermal fl uid.
If excessive amounts of thermal fl uid
are vented from the system, additional
thermal fl uid may be required in the
system. Contact Fulton for further
assistance.
Consider the following for thermal fl uid selection:
1. The Fulton coil design 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.
 AMOCO Transfer Oil 4199
 CHEVRON
 DOW G
 EXXON 43
 MOBIL
 MONSANTO
 MULTITHERM
 PARATHERM
 PETROCANADA T
 SHELL
 TEXACO
5. Any fl uid specifi cally designed for heat transfer use must also exhibit these
characteristics:
 Be a stable and homogenous liquid to a temperature of at least 100°F
(38°C) over and above the maximum intended temperature of utilization,
compatible with metals used in the installation, and tolerating contact
with atmospheric air.
 No solid matter in suspension.
 Non-toxic in the case of leakage.
 Suffi cient lubricity, i.e. not likely to cause seizure.
6. The thermal fl uid manufacturer must guarantee the characteristics of the
product, and verify that the fl uid bulk temperature limitation exceeds the
expected operating temperature
