AB&CO thermal fluid heating systems are high temperature process
heating systems, that uses a special thermal oil, a so-called
Heat Transfer Fluid (HTF), as the circulating heat carrier.
These types of heating systems are used for high performance industrial
processes - most often as an alternative to high pressure
saturated steam.
They become an attractive alternative
to the steam mainly due to much higher operating temperatures
on the media (HTF), maintaining low system pressure (often
atmospheric pressure). But there are numerous other
advantages, including
significant less overall operation costs. See more at "COMPARE
STEAM AND THERMAL FLUID".
As it appears from diagram below, steam at high temperatures
requires pressurised systems, whereas thermal oil (HTF) can be
operated atmospheric up to above 300°C. When pressurised,
the HTF can be operated even up to 400°C. |

The
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 2014/68/EU, EN-standards and
the recognised and demanding German standard for thermal oil heating systems
DIN 4754.
All AB&CO systems includes the heaters - whether they are 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.
AB&CO have
specialised in ThermoPacks as skid-mounted units and containerised solutions
(as shown on photo above / left). But systems are also delivered as separate
components e.g. the heaters alone (below photo)

The simple principle in thermal thermal fluid systems is heating by use
of a special thermal
oil - also called heat transfer fluids (HTF).
The HTF circulating through heaters (whether they are with
burners, electrical elements or as flue gas recuperators).
Thereafter
the HTF is led through a piping to one or several consumers, which can be for instance heat exchangers, air
heaters, tanks. 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. They come with full documentation and easy
readable instructions for handling, erecting, installation operation and maintenance. |
SPECIAL
SERVICE
The engineers of AB&CO 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.
