Supply of l-qb300 hot oil, mineral-type hot oil

The wallL-qb 300 hot oil mineral oil-type hot oil

 

The great wall l-qb 300-conductor hot oils mineral-type hot oils are made from a refined narrow-sortment mineral base oil with multifunctional additives. Thermal conductor oils, classified as l-qb280, l-qb300 and l-qc310 depending on the temperature used, are suitable for mandatory or non-compulsory open or closed heating systems not exceeding 280, 300°c and 310°c。

Performance characteristics

(b) the narrow range of fractions and the high number of primary fractions

(b) good high temperature oxidation (hto) stability performance with long useful life

High-temperature stability energy

(a) better heat bearing and conductability

(b) good fluidity at low temperatures

It is compatible with the material of the system and does not corrosive equipment。
