ChevronTexatherm 32详细说明 (浏览555次)
Description
Texatherm is a heat transfer fl uid formulated to meet the requirements of hot circulating systems operating at
temperatures of up to 320°C. Based on highly refi ned paraffi nic base oils with inherently good thermal stability,
Texatherm contains selected additives to enhance oxidation stability, protect against rusting or corrosion of steel
and copper, and prevent air entrainment and foaming.

Recommended Uses
Texatherm is recommended for use as a heat transfer fl uid in temperatures ranging from –15°C to a maximum bulk
temperature of 320°C. The maximum recommended fi lm temperature is 340°C. (The fi lm or skin temperature is the
temperature of the oil fi lm that is in direct contact with the internal wall of the heat exchanger tubes in the heater.)
Texatherm meets the requirements of the standard DIN 51522-Q for heat transfer oils.
Performance Benefi ts
1. Thermal and Oxidation Stability
Exhibits outstanding thermal and oxidation stability,
allowing operation at high temperatures for extended
periods.
2. Heat Transmission
Maximum heat transmission to the process vessel or
equipment allows the use of smaller circulating system
pumps, valves and heating coils.
3. High Thermal Conductivity
High thermal conductivity and low viscosity at the
relevant operating temperatures ensures high heat
transfer rates with limited pumping energy.
4. Low Vapor Pressure
Low vapor pressures at elevated temperatures minimize
evaporation, vapor lock and cavitation, and eliminates
the need for high-pressure piping and equipment.
