Chinese name：芐基甲苯絕緣油
English name：Monobenzyl toluene and Dibenzyl toluene
Commonly known as：RFCTHERM-330, M/DBT，Transformer Insulating Oil, Jarytherm BT06
Molecular Formula:C14H14(75%) C21H20(25%)Packaging and Storage: The product uses galvanised bucket packing. The net weight of each bucket is 200KG. The storage period is one year.
The M/DBT is recommended for heat transfer installations using
thermal fluid circulation.
It is particularly suited for installations combining heating and cooling cycles
such as Pharmaceutical and Specialty Chemicals industries. Our product is equivalent to the product Jarytherm BT06 from Europe.
