DelcoTerm® S DBT
Synthetic diathermic fluid consisting of a mixture of dibenzyltoluene isomers particularly suitable for oleothermal plants operating at temperatures between + 10 ° C and + 350 ° C for which the use of mineral oils is not possible.
SYNTHETIC DIATHERMIC OIL FOR HIGH TEMPERATURES
DelcoTerm® S DBT is a synthetic diathermic oil consisting of a mixture of
dibenzyltoluene isomers particularly suitable for oleothermal plants operating at very high temperatures where a mineral diathermic oil cannot be used.
The maximum operating temperatures that the fluid is able to withstand without cracking are of the order of
350 ° C
as mass temperature and 370 ° C as film temperature.
Like all synthetic diathermic fluids, when compared to a mineral oil, it has a higher resistance to cracking but a lower resistance to oxidation.
Its use is necessary and therefore recommended for systems where the fluid is subjected to working temperatures above 300 ° C and above all at localized temperatures above 340 ° C.
Due to its poor resistance to oxidation, it is absolutely necessary that the system that uses it has a secure defense against the possibility that the fluid comes into contact with the oxygen in the air. That is, the system must absolutely be equipped either with a pressurized vessel with nitrogen or with a reverse expansion barrel D.E.L.CO. or an efficient liquid guard.
