RFCTHERM-340(DBT)
CAS #: 26898-17-9
Product Description
RFCTHERM-340, also called as RFCTHERM-DBT, has a single molecular structure and high purity, its main ingredient is Dibenzyltoluene(abbrev: DBT), it is a high temperature liquid phase heat transfer fluid with excellent thermal stability. RFCTHERM-340 was developed for use at temperatures up to 340℃ in liquid phase heat transfer systems, Very high resistance to oxidation as well as high resistance to sludge and fouling can result in a significant reduction in capital investment, and reduced utility and maintenance costs as compared with other pressurized systems using more volatile high temperature heat transfer fluids. its chemical equivalent to TOTAL Jarytherm DBT and SOKEN NeoSK 1400.
The Temperature Range for use
Liquid: -30℃ to 340℃
