 Combination Deaerator/Thermal Buff er/Expansion Tank
Fulton Thermal’s e cient design combines the operation of the expansion,
deaerator, and thermal bu er tanks. Installation is considerably simpli ed by
virtue of this arrangement.
The expansion section is vital to the thermal  uid system. From ambient to
operating temperature, the thermal  uid in the system will typically expand
in the range of 25% to 50%, and a vessel capable of handling this expansion is
mandatory. The customer should con rm the expansion rate of the chosen  uid
and system volume.
At start up, the primary purpose of the deaerator section is to remove all volatiles
from the system to avoid pump cavitation. The deaerator section also allows air
to be vented from the system on a continuous basis during operation to avoid
oxidation of the thermal  uid, and removes other volatile particles generated by
the  uid itself during system operation. This section of the tank must be insulated.
