How is ATTSU's thermal oil expansion tank measured?

In boiler circuits that use oil as a thermal fluid, the expansion tank absorbs the increase in volume which the oil undergoes when the temperature of the boiler circuit increases while it is in operation.

The measurement of its dimensions depends on the temperature at which the system will operate, and the total volume calculated for the rest of the installation.

According to ATTSU's recommendations, the expansion tank should have a capacity of at least one third (30%) of the total of the overall installation in systems that reach 250 ºC while they are operational.

Thanks to the extensive experience of ATTSU’s the engineering and design team at, each thermal oil expansion tank is measured with the overall steam installation of which it forms a part.
