WARNING
All information in this manual is for
reference and guidance purposes,
and does not substitute for required
professional training, conduct,
and strict adherence to applicable
jurisdictional/professional codes and
regulations.
Fulton Companies is not responsible
for any injury or damage caused by
the use of inadequate fl uid.
Non-Fulton product information is for
reference purposes only. No Fulton
document may substitute for full
review of documentation available
from the component manufacturer.
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
contacts air.
Oxidation of the fl uid will also occur when hot thermal fl uid contacts air at a leak
in the system piping. Oxidized thermal fl uid becomes acidic and will damage the
thermal fl uid system. Thermal fl uid breakdown can occur in sections of piping
where there is a low fl ow condition. A low fl ow rate through the heater will result
in high fi lm temperatures leading to breakdown of the thermal fl uid.
