Above diagram and photo are examples of a thermal oil heating system according DIN 4754 for process air heating.

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 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 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.

For more extensive assistance in optimising new or existing systems, or for trouble shooting - consider our

Important for a trouble-free service is to choose a high quality thermal oil i.e. the heat transfer fluid (HTF). It is recommended to use a non-fouling, high temperature resistant 'White Mineral Oil' for the applications like AB&CO NF. This HTF is available on stock.

The HTF should be frequently tested by AB&CO laboratories in order to ensure a optimum and low cost operation of the heating systems.

Do not compromise on the HTF - use the right quality and check it frequently!
