The principle:

GESAB - HTI Thermal Oil Heaters are built according to DIN 4754 and the classification  Societies´ rules for pressure vessels. The forced circulation heaters of vertical or horizontal design are available of outputs of 200-10000kW. Thermal Oil Heaters, with at heating capacity of 800 kW and upward, can use heavy fuel oil burners (viscosity to 700 cSt at 50 C). On request, we can supply burners with a rotating cups and heaters designed for combustion of waste oil and sludge. Generated heat, by oil or gas flame will be transferred to the thermal oil system through bent pipes forming cylinders inside the heater. Within the inner cylinder - the combustion chamber - the heat is transferred by radiation and in the outer cylinder by convection.

Construction and design:

The radiating heater design employs two helically wound heating coils, fitted into each other and enclosed by a gas tight casing. The outside of the heater consists of a cladding of mineral wool insulated galvanized steel plate, The flue gases are triple-passed over the heating surface and transfer the heat through the tube wall to the heating medium, ensuring high thermal efficiency.

Advantages:
All these design futures make the GESAB - HTI Thermal Heaters an economical and efficient choice.

The generously dimensioned combustion chamber guarantees a long heater life due to no flame contact with the heating surface and that no temperature overloading occurs.

An innovative design of the tubes suspension ensures a safe and stress free thermal expansion.

Heat losses and external surface temperatures of the heater are kept low by the efficient use of insulation mineral wool and sheet metal cladding.

The safety feature eliminates the need for continuous attendance by the operating crew.
