4 CAUTION
Proper selection of thermal  uid is
critical to system performance.
If excessive amounts of thermal
 uid are vented from the system,
additional thermal  uid may be
required in the system. Contact Fulton
for further information.
product, and verify that the  uid bulk temperature limitation exceeds the
expected operating temperature
7. After a  uid is selected, refer to the manufacturer’s recommendations,
published in compliance with the Occupational Safety and Health
Administration (OSHA).
8. If the  uid expansion volume from 50°F to 600°F (10 C to 316°C) exceeds
20% of the initial  uid volume, consult Fulton Thermal Corporation.
 Routine Analysis of Heat Transfer Fluid
Nearly all leading manufacturers of heat transfer  uids provide an after
sales service to monitor the condition of the  uid in operation and make
recommendations when replacement becomes necessary.
Each  uid manufacturer has procedures for regular testing and analysis of the
 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  rst weeks of
system operation.
Fulton Thermal Corporation recommends that the thermal  uid in your system
be analyzed within the  rst two months after startup and annually thereafter.
During the  rst few months of operation, sampling may be carried out at
frequent intervals to con rm that system performance has been predicted
correctly.
If the supplier of your thermal  uid does not contact you within four weeks of
commissioning, contact the supplier and make certain that the “ ll” is registered
for routine analysis.
 Thermal Fluid Breakdown
The possibilities of thermal  uid breakdown are very slim in a typical closed loop
thermal  uid system. Fulton’s combination expansion/deaerator/thermal bu er
tank creates a “cold seal” of  uid that is slightly above ambient temperature. This
prevents oxidation that will otherwise happen when high temperature  uid
contacts air.
Oxidation of the  uid will also occur when hot thermal  uid contacts air at a leak
in the system piping. Oxidized thermal  uid becomes acidic and will damage the
thermal  uid system. Thermal  uid breakdown can occur in sections of piping
where there is a low  ow condition. A low  ow rate through the heater will result
in high  lm temperatures leading to breakdown of the thermal  uid.
 THERMAL FLUID BREAKDOWN PREVENTION
 Multiple pressure switches and a di erential pressure switch are used to
prevent this condition from occurring. See Figure 6. These safeties must
not be bypassed at any time.
 Exceeding the maximum operating temperature of the thermal  uid will
