CAUTION
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 information.
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
7. After a fl uid is selected, refer to the manufacturer’s recommendations,
published in compliance with the Occupational Safety and Health
Administration (OSHA).
8. If the fl uid expansion volume from 50 F to 600 F (10 C to 316 C) exceeds
20% of the initial fl uid volume, consult Fulton Thermal Corporation.
Routine Analysis of Heat Transfer Fluid
Nearly all leading manufacturers of heat transfer fl uids provide an after
sales service to monitor the condition of the fl uid in operation and make
recommendations when replacement becomes necessary.
Each fl uid manufacturer has procedures for regular testing and analysis of the
fl uid. These usually allow for a sample to be taken and analyzed at least once a
year, although actual frequency will depend on operating temperature, number
of hours operated weekly, and the results of tests made during the fi rst weeks of
system operation.
Fulton Thermal Corporation recommends that the thermal fl uid in your system
be analyzed within the fi rst two months after startup and annually thereafter.
During the fi rst few months of operation, sampling may be carried out at
frequent intervals to confi rm that system performance has been predicted
correctly.
If the supplier of your thermal fl uid does not contact you within four weeks of
commissioning, contact the supplier and make certain that the “fi ll” is registered
for routine analysis.
Thermal Fluid Breakdown
The possibilities of thermal fl uid breakdown are very slim in a typical closed loop
thermal fl uid system. Fulton’s combination expansion/deaerator/thermal buff er
tank creates a “cold seal” of fl uid that is slightly above ambient temperature. This
prevents oxidation that will otherwise happen when high temperature fl uid
