FT-C Vertical Electric Thermal Fluid Heater Manual 12 2013 ISSUE 1
Fulton Ltd's efcient design combines the operation of the expansion, deaerator, and thermal buffer
tanks. Installation is considerably simplied by virtue of this arrangement.
The tank will be constructed of carbon steel. It shall be supplied with expansion section liquid level
switch and PN16 anged connections.
The tank may be built to BS EN 13445: 2009 upon request. Non-coded tanks should not be
pressurised above 0.5 barg.
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%-50%, and a vessel capable
of handling this expansion is mandatory. The customer should conrm 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 oxygen 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 should be
insulated.
A system of interconnecting pipe work in the thermal buffer tank section prevents the movement of
any oil that has not cooled sufciently into the expansion section. This avoids contact of very high
thermal uid temperature with oxygen contained in the atmosphere, which causes uid breakdown.
DO NOT insulate this section.
