AB&CO thermal fluid systems are high temperature process
heating systems, used for high performance industrial
processes - most often as an alternative to high pressure
steam. An attractive alternative due to much higher media
operating temperatures at low pressure, but also because of
significant less overall operation costs. See more at "COMPARE
STEAM AND THERMAL FLUID".
As it appears from above diagram, steam at high temperatures
requires pressurised systems, whereas thermal oil can be
operated atmospheric up to above 300°C. When pressurised,
the thermal oil it can be operated even up to 400°C.

ThermoPack units (thermal oil heater units) comprise a heater,
pressure vessel, main pump, heat exchangers,
tanks, armatures, safety equipment, instrumentation, control system and the
tanks for expansion, dearating & de-gassing, buffer and emptying including
arrangement for filling/emptying system, barrels and tank.
The standard follows European code including PED 97/23 CE, EN-standards and
the recognised and demanding German standard for thermal oil heating systems
All AB&CO systems includes the TT BOILERS heaters - whether is is oil-fired,
gas-fired, electrical heated or exhaust gas recuperative. They are delivered
with a full documentation package comprising drawings, diagrams, data
sheets, specifications, instructions for installation/handling, operating
and maintenance - and all required certificates necessary for deliveries
within the EU.
Environmental solutions are
available in many alternative design - including mounting of economiser and thermal oil
heated by utilising waste heat in, for instance, hot flue gas.
specialised in ThermoPacks as skid-mounted units and containerised solutions
(as shown on photo above / left). But system are also delivered as separate
components e.g. the heaters alone (below photo)
TT BOILERS oil-fired heaters at bitumen plant
The simple principle in thermal thermal fluid systems is heating by use
of a special thermal
fluid (non-flammable oil) circulating the through heaters (with
burners, electrical elements or flue gas recuperators).
the fluid is led to one or several consumers, which can be for instance heat exchangers, air
heaters, reactors, convectors, rollers etc.

These systems are all tailor-made and they are
always delivered as complete packages for assembly on site, or as
skid-mounted units when the size allows it - and with full documentation and easy
readable instructions for handling, erecting, installation and maintenance.
The engineers of AB&CO · TT
BOILERS are able to assist in the operation of the thermal fluid heating
system by frequently analysing samples of the circulating oil. From the
analysis it is possible to guide for an optimum performance and long life
time for both the oil and the plant.
